Merge tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pul removal of obsolete architecture ports from Arnd Bergmann:
 "This removes the entire architecture code for blackfin, cris, frv,
  m32r, metag, mn10300, score, and tile, including the associated device
  drivers.

  I have been working with the (former) maintainers for each one to
  ensure that my interpretation was right and the code is definitely
  unused in mainline kernels. Many had fond memories of working on the
  respective ports to start with and getting them included in upstream,
  but also saw no point in keeping the port alive without any users.

  In the end, it seems that while the eight architectures are extremely
  different, they all suffered the same fate: There was one company in
  charge of an SoC line, a CPU microarchitecture and a software
  ecosystem, which was more costly than licensing newer off-the-shelf
  CPU cores from a third party (typically ARM, MIPS, or RISC-V). It
  seems that all the SoC product lines are still around, but have not
  used the custom CPU architectures for several years at this point. In
  contrast, CPU instruction sets that remain popular and have actively
  maintained kernel ports tend to all be used across multiple licensees.

  [ See the new nds32 port merged in the previous commit for the next
    generation of "one company in charge of an SoC line, a CPU
    microarchitecture and a software ecosystem"   - Linus ]

  The removal came out of a discussion that is now documented at
  https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
  marking any ports as deprecated but remove them all at once after I
  made sure that they are all unused. Some architectures (notably tile,
  mn10300, and blackfin) are still being shipped in products with old
  kernels, but those products will never be updated to newer kernel
  releases.

  After this series, we still have a few architectures without mainline
  gcc support:

   - unicore32 and hexagon both have very outdated gcc releases, but the
     maintainers promised to work on providing something newer. At least
     in case of hexagon, this will only be llvm, not gcc.

   - openrisc, risc-v and nds32 are still in the process of finishing
     their support or getting it added to mainline gcc in the first
     place. They all have patched gcc-7.3 ports that work to some
     degree, but complete upstream support won't happen before gcc-8.1.
     Csky posted their first kernel patch set last week, their situation
     will be similar

  [ Palmer Dabbelt points out that RISC-V support is in mainline gcc
    since gcc-7, although gcc-7.3.0 is the recommended minimum  - Linus ]"

This really says it all:

-1. Blackfin GPIO introduction
-
-    There are many GPIO pins on Blackfin. Most of these pins are muxed to
-    multi-functions. They can be configured as peripheral, or just as GPIO,
-    configured to input with interrupt enabled, or output.
-
-    For detailed information, please see "arch/blackfin/kernel/bfin_gpio.c",
-    or the relevant HRM.
-
-
-2. Avoiding resource conflict
-
-    Followed function groups are used to avoiding resource conflict,
-    - Use the pin as peripheral,
-	int peripheral_request(unsigned short per, const char *label);
-	int peripheral_request_list(const unsigned short per[], const char *label);
-	void peripheral_free(unsigned short per);
-	void peripheral_free_list(const unsigned short per[]);
-    - Use the pin as GPIO,
-	int bfin_gpio_request(unsigned gpio, const char *label);
-	void bfin_gpio_free(unsigned gpio);
-    - Use the pin as GPIO interrupt,
-	int bfin_gpio_irq_request(unsigned gpio, const char *label);
-	void bfin_gpio_irq_free(unsigned gpio);
-
-    The request functions will record the function state for a certain pin,
-    the free functions will clear its function state.
-    Once a pin is requested, it can't be requested again before it is freed by
-    previous caller, otherwise kernel will dump stacks, and the request
-    function fail.
-    These functions are wrapped by other functions, most of the users need not
-    care.
-
-
-3. But there are some exceptions
-    - Kernel permit the identical GPIO be requested both as GPIO and GPIO
-    interrupt.
-    Some drivers, like gpio-keys, need this behavior. Kernel only print out
-    warning messages like,
-	bfin-gpio: GPIO 24 is already reserved by gpio-keys: BTN0, and you are
-configuring it as IRQ!
-
-        Note: Consider the case that, if there are two drivers need the
-	identical GPIO, one of them use it as GPIO, the other use it as
-	GPIO interrupt. This will really cause resource conflict. So if
-	there is any abnormal driver behavior, please check the bfin-gpio
-	warning messages.
-
-    - Kernel permit the identical GPIO be requested from the same driver twice.
-

Documentation/blackfin/bfin-spi-notes.txt

-SPI Chip Select behavior:
-
-With the Blackfin on-chip SPI peripheral, there is some logic tied to the CPHA
-bit whether the Slave Select Line is controlled by hardware (CPHA=0) or
-controlled by software (CPHA=1). However, the Linux SPI bus driver assumes that
-the Slave Select is always under software control and being asserted during
-the entire SPI transfer. - And not just bits_per_word duration.
-
-In most cases you can utilize SPI MODE_3 instead of MODE_0 to work-around this
-behavior. If your SPI slave device in question requires SPI MODE_0 or MODE_2
-timing, you can utilize the GPIO controlled SPI Slave Select option instead.
-In this case, you should use GPIO based CS for all of your slaves and not just
-the ones using mode 0 or 2 in order to guarantee correct CS toggling behavior.
-
-You can even use the same pin whose peripheral role is a SSEL,
-but use it as a GPIO instead.

-Linux on the CRIS architecture
-==============================
-
-This is a port of Linux to Axis Communications ETRAX 100LX,
-ETRAX FS and ARTPEC-3 embedded network CPUs.
-
-For more information about CRIS and ETRAX please see further below.
-
-In order to compile this you need a version of gcc with support for the
-ETRAX chip family. Please see this link for more information on how to
-download the compiler and other tools useful when building and booting
-software for the ETRAX platform:
-
-http://developer.axis.com/wiki/doku.php?id=axis:install-howto-2_20
-
-What is CRIS ?
---------------
-
-CRIS is an acronym for 'Code Reduced Instruction Set'. It is the CPU
-architecture in Axis Communication AB's range of embedded network CPU's,
-called ETRAX.
-
-The ETRAX 100LX chip
---------------------
-
-For reference, please see the following link:
-
-http://www.axis.com/products/dev_etrax_100lx/index.htm
-
-The ETRAX 100LX is a 100 MIPS processor with 8kB cache, MMU, and a very broad
-range of built-in interfaces, all with modern scatter/gather DMA.
-
-Memory interfaces:
-
-	* SRAM
-	* NOR-flash/ROM
-	* EDO or page-mode DRAM
-	* SDRAM
-
-I/O interfaces:
-
-	* one 10/100 Mbit/s ethernet controller
-	* four serial-ports (up to 6 Mbit/s)
-	* two synchronous serial-ports for multimedia codec's etc.
-	* USB host controller and USB slave
-	* ATA
-	* SCSI
-	* two parallel-ports
-	* two generic 8-bit ports
-
-	(not all interfaces are available at the same time due to chip pin
-         multiplexing)
-
-ETRAX 100LX is CRISv10 architecture.
-
-
-The ETRAX FS and ARTPEC-3 chips
--------------------------------
-
-The ETRAX FS is a 200MHz 32-bit RISC processor with on-chip 16kB
-I-cache and 16kB D-cache and with a wide range of device interfaces
-including multiple high speed serial ports and an integrated USB 1.1 PHY.
-
-The ARTPEC-3 is a variant of the ETRAX FS with additional IO-units
-used by the Axis Communications network cameras.
-
-See below link for more information:
-
-http://www.axis.com/products/dev_etrax_fs/index.htm
-
-ETRAX FS and ARTPEC-3 are both CRISv32 architectures.
-
-Bootlog
--------
-
-Just as an example, this is the debug-output from a boot of Linux 2.4 on
-a board with ETRAX 100LX. The displayed BogoMIPS value is 5 times too small :)
-At the end you see some user-mode programs booting like telnet and ftp daemons.

Documentation/frv/atomic-ops.txt

-			       =====================================
-			       FUJITSU FR-V KERNEL ATOMIC OPERATIONS
-			       =====================================
-
-On the FR-V CPUs, there is only one atomic Read-Modify-Write operation: the SWAP/SWAPI
-instruction. Unfortunately, this alone can't be used to implement the following operations:
-
- (*) Atomic add to memory
-
- (*) Atomic subtract from memory
-
- (*) Atomic bit modification (set, clear or invert)
-
- (*) Atomic compare and exchange
-
-On such CPUs, the standard way of emulating such operations in uniprocessor mode is to disable
-interrupts, but on the FR-V CPUs, modifying the PSR takes a lot of clock cycles, and it has to be
-done twice. This means the CPU runs for a relatively long time with interrupts disabled,
-potentially having a great effect on interrupt latency.
-
-
-=============
-NEW ALGORITHM
-=============
-
-To get around this, the following algorithm has been implemented. It operates in a way similar to
-the LL/SC instruction pairs supported on a number of platforms.
-
- (*) The CCCR.CC3 register is reserved within the kernel to act as an atomic modify abort flag.
-
- (*) In the exception prologues run on kernel->kernel entry, CCCR.CC3 is set to 0 (Undefined
-     state).
-
- (*) All atomic operations can then be broken down into the following algorithm:
-
-     (1) Set ICC3.Z to true and set CC3 to True (ORCC/CKEQ/ORCR).
-
-     (2) Load the value currently in the memory to be modified into a register.
-
-     (3) Make changes to the value.
-
-     (4) If CC3 is still True, simultaneously and atomically (by VLIW packing):
-
-	 (a) Store the modified value back to memory.
-
-	 (b) Set ICC3.Z to false (CORCC on GR29 is sufficient for this - GR29 holds the current
-	     task pointer in the kernel, and so is guaranteed to be non-zero).
-
-     (5) If ICC3.Z is still true, go back to step (1).
-
-This works in a non-SMP environment because any interrupt or other exception that happens between
-steps (1) and (4) will set CC3 to the Undefined, thus aborting the store in (4a), and causing the
-condition in ICC3 to remain with the Z flag set, thus causing step (5) to loop back to step (1).
-
-
-This algorithm suffers from two problems:
-
- (1) The condition CCCR.CC3 is cleared unconditionally by an exception, irrespective of whether or
-     not any changes were made to the target memory location during that exception.
-
- (2) The branch from step (5) back to step (1) may have to happen more than once until the store
-     manages to take place. In theory, this loop could cycle forever because there are too many
-     interrupts coming in, but it's unlikely.
-
-
-=======
-EXAMPLE
-=======
-
-Taking an example from include/asm-frv/atomic.h:
-
-	static inline int atomic_add_return(int i, atomic_t *v)
-	{
-		unsigned long val;
-
-		asm("0:						\n"
-
-It starts by setting ICC3.Z to true for later use, and also transforming that into CC3 being in the
-True state.
-
-		    "	orcc		gr0,gr0,gr0,icc3	\n"	<-- (1)
-		    "	ckeq		icc3,cc7		\n"	<-- (1)
-
-Then it does the load. Note that the final phase of step (1) is done at the same time as the
-load. The VLIW packing ensures they are done simultaneously. The ".p" on the load must not be
-removed without swapping the order of these two instructions.
-
-		    "	ld.p		%M0,%1			\n"	<-- (2)
-		    "	orcr		cc7,cc7,cc3		\n"	<-- (1)
-
-Then the proposed modification is generated. Note that the old value can be retained if required
-(such as in test_and_set_bit()).
-
-		    "	add%I2		%1,%2,%1		\n"	<-- (3)
-
-Then it attempts to store the value back, contingent on no exception having cleared CC3 since it
-was set to True.
-
-		    "	cst.p		%1,%M0		,cc3,#1	\n"	<-- (4a)
-
-It simultaneously records the success or failure of the store in ICC3.Z.
-
-		    "	corcc		gr29,gr29,gr0	,cc3,#1	\n"	<-- (4b)
-
-Such that the branch can then be taken if the operation was aborted.
-
-		    "	beq		icc3,#0,0b		\n"	<-- (5)
-		    : "+U"(v->counter), "=&r"(val)
-		    : "NPr"(i)
-		    : "memory", "cc7", "cc3", "icc3"
-		    );
-
-		return val;
-	}
-
-
-=============
-CONFIGURATION
-=============
-
-The atomic ops implementation can be made inline or out-of-line by changing the
-CONFIG_FRV_OUTOFLINE_ATOMIC_OPS configuration variable. Making it out-of-line has a number of
-advantages:
-
- - The resulting kernel image may be smaller
- - Debugging is easier as atomic ops can just be stepped over and they can be breakpointed
-
-Keeping it inline also has a number of advantages:
-
- - The resulting kernel may be Faster
-   - no out-of-line function calls need to be made
-   - the compiler doesn't have half its registers clobbered by making a call
-
-The out-of-line implementations live in arch/frv/lib/atomic-ops.S.

Documentation/frv/booting.txt

-			  =========================
-			  BOOTING FR-V LINUX KERNEL
-			  =========================
-
-======================
-PROVIDING A FILESYSTEM
-======================
-
-First of all, a root filesystem must be made available. This can be done in
-one of two ways:
-
-  (1) NFS Export
-
-      A filesystem should be constructed in a directory on an NFS server that
-      the target board can reach. This directory should then be NFS exported
-      such that the target board can read and write into it as root.
-
-  (2) Flash Filesystem (JFFS2 Recommended)
-
-      In this case, the image must be stored or built up on flash before it
-      can be used. A complete image can be built using the mkfs.jffs2 or
-      similar program and then downloaded and stored into flash by RedBoot.
-
-
-========================
-LOADING THE KERNEL IMAGE
-========================
-
-The kernel will need to be loaded into RAM by RedBoot (or by some alternative
-boot loader) before it can be run. The kernel image (arch/frv/boot/Image) may
-be loaded in one of three ways:
-
-  (1) Load from Flash
-
-      This is the simplest. RedBoot can store an image in the flash (see the
-      RedBoot documentation) and then load it back into RAM. RedBoot keeps
-      track of the load address, entry point and size, so the command to do
-      this is simply:
-
-	fis load linux
-
-      The image is then ready to be executed.
-
-  (2) Load by TFTP
-
-      The following command will download a raw binary kernel image from the
-      default server (as negotiated by BOOTP) and store it into RAM:
-
-	load -b 0x00100000 -r /tftpboot/image.bin
-
-      The image is then ready to be executed.
-
-  (3) Load by Y-Modem
-
-      The following command will download a raw binary kernel image across the
-      serial port that RedBoot is currently using:
-
-	load -m ymodem -b 0x00100000 -r zImage
-
-      The serial client (such as minicom) must then be told to transmit the
-      program by Y-Modem.
-
-      When finished, the image will then be ready to be executed.
-
-
-==================
-BOOTING THE KERNEL
-==================
-
-Boot the image with the following RedBoot command:
-
-	exec -c "<CMDLINE>" 0x00100000
-
-For example:
-
-	exec -c "console=ttySM0,115200 ip=:::::dhcp root=/dev/mtdblock2 rw"
-
-This will start the kernel running. Note that if the GDB-stub is compiled in,
-then the kernel will immediately wait for GDB to connect over serial before
-doing anything else. See the section on kernel debugging with GDB.
-
-The kernel command line <CMDLINE> tells the kernel where its console is and
-how to find its root filesystem. This is made up of the following components,
-separated by spaces:
-
-  (*) console=ttyS<x>[,<baud>[<parity>[<bits>[<flow>]]]]
-
-      This specifies that the system console should output through on-chip
-      serial port <x> (which can be "0" or "1").
-
-      <baud> is a standard baud rate between 1200 and 115200 (default 9600).
-
-      <parity> is a parity setting of "N", "O", "E", "M" or "S" for None, Odd,
-      Even, Mark or Space. "None" is the default.
-
-      <stop> is "7" or "8" for the number of bits per character. "8" is the
-      default.
-
-      <flow> is "r" to use flow control (XCTS on serial port 2 only). The
-      default is to not use flow control.
-
-      For example:
-
-	console=ttyS0,115200
-
-      To use the first on-chip serial port at baud rate 115200, no parity, 8
-      bits, and no flow control.
-
-  (*) root=<xxxx>
-
-      This specifies the device upon which the root filesystem resides. It
-      may be specified by major and minor number, device path, or even
-      partition uuid, if supported.  For example:
-
-	/dev/nfs	NFS root filesystem
-	/dev/mtdblock3	Fourth RedBoot partition on the System Flash
-	PARTUUID=00112233-4455-6677-8899-AABBCCDDEEFF/PARTNROFF=1
-		first partition after the partition with the given UUID
-	253:0		Device with major 253 and minor 0
-
-      Authoritative information can be found in
-      "Documentation/admin-guide/kernel-parameters.rst".
-
-  (*) rw
-
-      Start with the root filesystem mounted Read/Write.
-
-  The remaining components are all optional:
-
-  (*) ip=<ip>::::<host>:<iface>:<cfg>
-
-      Configure the network interface. If <cfg> is "off" then <ip> should
-      specify the IP address for the network device <iface>. <host> provide
-      the hostname for the device.
-
-      If <cfg> is "bootp" or "dhcp", then all of these parameters will be
-      discovered by consulting a BOOTP or DHCP server.
-
-      For example, the following might be used:
-
-	ip=192.168.73.12::::frv:eth0:off
-
-      This sets the IP address on the VDK motherboard RTL8029 ethernet chipset
-      (eth0) to be 192.168.73.12, and sets the board's hostname to be "frv".
-
-  (*) nfsroot=<server>:<dir>[,v<vers>]
-
-      This is mandatory if "root=/dev/nfs" is given as an option. It tells the
-      kernel the IP address of the NFS server providing its root filesystem,
-      and the pathname on that server of the filesystem.
-
-      The NFS version to use can also be specified. v2 and v3 are supported by
-      Linux.
-
-      For example:
-
-	nfsroot=192.168.73.1:/nfsroot-frv
-
-  (*) profile=1
-
-      Turns on the kernel profiler (accessible through /proc/profile).
-
-  (*) console=gdb0
-
-      This can be used as an alternative to the "console=ttyS..." listed
-      above. I tells the kernel to pass the console output to GDB if the
-      gdbstub is compiled in to the kernel.
-
-      If this is used, then the gdbstub passes the text to GDB, which then
-      simply dumps it to its standard output.
-
-  (*) mem=<xxx>M
-
-      Normally the kernel will work out how much SDRAM it has by reading the
-      SDRAM controller registers. That can be overridden with this
-      option. This allows the kernel to be told that it has <xxx> megabytes of
-      memory available.
-
-  (*) init=<prog> [<arg> [<arg> [<arg> ...]]]
-
-      This tells the kernel what program to run initially. By default this is
-      /sbin/init, but /sbin/sash or /bin/sh are common alternatives.

Documentation/frv/clock.txt

-Clock scaling
--------------
-
-The kernel supports scaling of CLCK.CMODE, CLCK.CM and CLKC.P0 clock
-registers. If built with CONFIG_PM and CONFIG_SYSCTL options enabled, four
-extra files will appear in the directory /proc/sys/pm/. Reading these files
-will show:
-
-      p0		-- current value of the P0 bit in CLKC register.
-      cm		-- current value of the CM bits in CLKC register.
-      cmode		-- current value of the CMODE bits in CLKC register.
-
-On all boards, the 'p0' file should also be writable, and either '1' or '0'
-can be rewritten, to set or clear the CLKC_P0 bit respectively, hence
-controlling whether the resource bus rate clock is halved.
-
-The 'cm' file should also be available on all boards. '0' can be written to it
-to shift the board into High-Speed mode (normal), and '1' can be written to
-shift the board into Medium-Speed mode. Selecting Low-Speed mode is not
-supported by this interface, even though some CPUs do support it.
-
-On the boards with FR405 CPU (i.e. CB60 and CB70), the 'cmode' file is also
-writable, allowing the CPU core speed (and other clock speeds) to be
-controlled from userspace.
-
-
-Determining current and possible settings
------------------------------------------
-
-The current state and the available masks can be found in /proc/cpuinfo. For
-example, on the CB70:
-
-	# cat /proc/cpuinfo
-	CPU-Series:     fr400
-	CPU-Core:       fr405, gr0-31, BE, CCCR
-	CPU:            mb93405
-	MMU:            Prot
-	FP-Media:       fr0-31, Media
-	System:         mb93091-cb70, mb93090-mb00
-	PM-Controls:    cmode=0xd31f, cm=0x3, p0=0x3, suspend=0x9
-	PM-Status:      cmode=3, cm=0, p0=0
-	Clock-In:       50.00 MHz
-	Clock-Core:     300.00 MHz
-	Clock-SDRAM:    100.00 MHz
-	Clock-CBus:     100.00 MHz
-	Clock-Res:      50.00 MHz
-	Clock-Ext:      50.00 MHz
-	Clock-DSU:      25.00 MHz
-	BogoMips:       300.00
-
-And on the PDK, the PM lines look like the following:
-
-	PM-Controls:    cm=0x3, p0=0x3, suspend=0x9
-	PM-Status:      cmode=9, cm=0, p0=0
-
-The PM-Controls line, if present, will indicate which /proc/sys/pm files can
-be set to what values. The specification values are bitmasks; so, for example,
-"suspend=0x9" indicates that 0 and 3 can be written validly to
-/proc/sys/pm/suspend.
-
-The PM-Controls line will only be present if CONFIG_PM is configured to Y.
-
-The PM-Status line indicates which clock controls are set to which value. If
-the file can be read, then the suspend value must be 0, and so that's not
-included.

Documentation/frv/configuring.txt

-		   =======================================
-		   FUJITSU FR-V LINUX KERNEL CONFIGURATION
-		   =======================================
-
-=====================
-CONFIGURATION OPTIONS
-=====================
-
-The most important setting is in the "MMU support options" tab (the first
-presented in the configuration tools available):
-
- (*) "Kernel Type"
-
-     This options allows selection of normal, MMU-requiring linux, and uClinux
-     (which doesn't require an MMU and doesn't have inter-process protection).
-
-There are a number of settings in the "Processor type and features" section of
-the kernel configuration that need to be considered.
-
- (*) "CPU"
-
-     The register and instruction sets at the core of the processor. This can
-     only be set to "FR40x/45x/55x" at the moment - but this permits usage of
-     the kernel with MB93091 CB10, CB11, CB30, CB41, CB60, CB70 and CB451
-     CPU boards, and with the MB93093 PDK board.
-
- (*) "System"
-
-     This option allows a choice of basic system. This governs the peripherals
-     that are expected to be available.
-
- (*) "Motherboard"
-
-     This specifies the type of motherboard being used, and the peripherals
-     upon it. Currently only "MB93090-MB00" can be set here.
-
- (*) "Default cache-write mode"
-
-     This controls the initial data cache write management mode. By default
-     Write-Through is selected, but Write-Back (Copy-Back) can also be
-     selected. This can be changed dynamically once the kernel is running (see
-     features.txt).
-
-There are some architecture specific configuration options in the "General
-Setup" section of the kernel configuration too:
-
- (*) "Reserve memory uncached for (PCI) DMA"
-
-     This requests that a uClinux kernel set aside some memory in an uncached
-     window for the use as consistent DMA memory (mainly for PCI). At least a
-     megabyte will be allocated in this way, possibly more. Any memory so
-     reserved will not be available for normal allocations.
-
- (*) "Kernel support for ELF-FDPIC binaries"
-
-     This enables the binary-format driver for the new FDPIC ELF binaries that
-     this platform normally uses. These binaries are totally relocatable -
-     their separate sections can relocated independently, allowing them to be
-     shared on uClinux where possible. This should normally be enabled.
-
- (*) "Kernel image protection"
-
-     This makes the protection register governing access to the core kernel
-     image prohibit access by userspace programs. This option is available on
-     uClinux only.
-
-There are also a number of settings in the "Kernel Hacking" section of the
-kernel configuration especially for debugging a kernel on this
-architecture. See the "gdbstub.txt" file for information about those.
-
-
-======================
-DEFAULT CONFIGURATIONS
-======================
-
-The kernel sources include a number of example default configurations:
-
- (*) defconfig-mb93091
-
-     Default configuration for the MB93091-VDK with both CPU board and
-     MB93090-MB00 motherboard running uClinux.
-
-
- (*) defconfig-mb93091-fb
-
-     Default configuration for the MB93091-VDK with CPU board,
-     MB93090-MB00 motherboard, and DAV board running uClinux.
-     Includes framebuffer driver.
-
-

-			     ====================
-			     DEBUGGING FR-V LINUX
-			     ====================
-
-
-The kernel contains a GDB stub that talks GDB remote protocol across a serial
-port. This permits GDB to single step through the kernel, set breakpoints and
-trap exceptions that happen in kernel space and interrupt execution. It also
-permits the NMI interrupt button or serial port events to jump the kernel into
-the debugger.
-
-On the CPUs that have on-chip UARTs (FR400, FR403, FR405, FR555), the
-GDB stub hijacks a serial port for its own purposes, and makes it
-generate level 15 interrupts (NMI). The kernel proper cannot see the serial
-port in question under these conditions.
-
-On the MB93091-VDK CPU boards, the GDB stub uses UART1, which would otherwise
-be /dev/ttyS1. On the MB93093-PDK, the GDB stub uses UART0. Therefore, on the
-PDK there is no externally accessible serial port and the serial port to
-which the touch screen is attached becomes /dev/ttyS0.
-
-Note that the GDB stub runs entirely within CPU debug mode, and so should not
-incur any exceptions or interrupts whilst it is active. In particular, note
-that the clock will lose time since it is implemented in software.
-
-
-==================
-KERNEL PREPARATION
-==================
-
-Firstly, a debuggable kernel must be built. To do this, unpack the kernel tree
-and copy the configuration that you wish to use to .config. Then reconfigure
-the following things on the "Kernel Hacking" tab:
-
-  (*) "Include debugging information"
-
-      Set this to "Y". This causes all C and Assembly files to be compiled
-      to include debugging information.
-
-  (*) "In-kernel GDB stub"
-
-      Set this to "Y". This causes the GDB stub to be compiled into the
-      kernel.
-
-  (*) "Immediate activation"
-
-      Set this to "Y" if you want the GDB stub to activate as soon as possible
-      and wait for GDB to connect. This allows you to start tracing right from
-      the beginning of start_kernel() in init/main.c.
-
-  (*) "Console through GDB stub"
-
-      Set this to "Y" if you wish to be able to use "console=gdb0" on the
-      command line. That tells the kernel to pass system console messages to
-      GDB (which then prints them on its standard output). This is useful when
-      debugging the serial drivers that'd otherwise be used to pass console
-      messages to the outside world.
-
-Then build as usual, download to the board and execute. Note that if
-"Immediate activation" was selected, then the kernel will wait for GDB to
-attach. If not, then the kernel will boot immediately and GDB will have to
-interrupt it or wait for an exception to occur before doing anything with
-the kernel.
-
-
-=========================
-KERNEL DEBUGGING WITH GDB
-=========================
-
-Set the serial port on the computer that's going to run GDB to the appropriate
-baud rate. Assuming the board's debug port is connected to ttyS0/COM1 on the
-computer doing the debugging:
-
-	stty -F /dev/ttyS0 115200
-
-Then start GDB in the base of the kernel tree:
-
-	frv-uclinux-gdb linux		[uClinux]
-
-Or:
-
-	frv-uclinux-gdb vmlinux		[MMU linux]
-
-When the prompt appears:
-
-	GNU gdb frv-031024
-	Copyright 2003 Free Software Foundation, Inc.
-	GDB is free software, covered by the GNU General Public License, and you are
-	welcome to change it and/or distribute copies of it under certain conditions.
-	Type "show copying" to see the conditions.
-	There is absolutely no warranty for GDB.  Type "show warranty" for details.
-	This GDB was configured as "--host=i686-pc-linux-gnu --target=frv-uclinux"...
-	(gdb)
-
-Attach to the board like this:
-
-        (gdb) target remote /dev/ttyS0
-	Remote debugging using /dev/ttyS0
-	start_kernel () at init/main.c:395
-	(gdb)
-
-This should show the appropriate lines from the source too. The kernel can
-then be debugged almost as if it's any other program.
-
-
-===============================
-INTERRUPTING THE RUNNING KERNEL
-===============================
-
-The kernel can be interrupted whilst it is running, causing a jump back to the
-GDB stub and the debugger:
-
-  (*) Pressing Ctrl-C in GDB. This will cause GDB to try and interrupt the
-      kernel by sending an RS232 BREAK over the serial line to the GDB
-      stub. This will (mostly) immediately interrupt the kernel and return it
-      to the debugger.
-
-  (*) Pressing the NMI button on the board will also cause a jump into the
-      debugger.
-
-  (*) Setting a software breakpoint. This sets a break instruction at the
-      desired location which the GDB stub then traps the exception for.
-
-  (*) Setting a hardware breakpoint. The GDB stub is capable of using the IBAR
-      and DBAR registers to assist debugging.
-
-Furthermore, the GDB stub will intercept a number of exceptions automatically
-if they are caused by kernel execution. It will also intercept BUG() macro
-invocation.
-

Documentation/frv/kernel-ABI.txt

-			=================================
-			INTERNAL KERNEL ABI FOR FR-V ARCH
-			=================================
-
-The internal FRV kernel ABI is not quite the same as the userspace ABI. A
-number of the registers are used for special purposed, and the ABI is not
-consistent between modules vs core, and MMU vs no-MMU.
-
-This partly stems from the fact that FRV CPUs do not have a separate
-supervisor stack pointer, and most of them do not have any scratch
-registers, thus requiring at least one general purpose register to be
-clobbered in such an event. Also, within the kernel core, it is possible to
-simply jump or call directly between functions using a relative offset.
-This cannot be extended to modules for the displacement is likely to be too
-far. Thus in modules the address of a function to call must be calculated
-in a register and then used, requiring two extra instructions.
-
-This document has the following sections:
-
- (*) System call register ABI
- (*) CPU operating modes
- (*) Internal kernel-mode register ABI
- (*) Internal debug-mode register ABI
- (*) Virtual interrupt handling
-
-
-========================
-SYSTEM CALL REGISTER ABI
-========================
-
-When a system call is made, the following registers are effective:
-
-	REGISTERS	CALL			RETURN
-	===============	=======================	=======================
-	GR7		System call number	Preserved
-	GR8		Syscall arg #1		Return value
-	GR9-GR13	Syscall arg #2-6	Preserved
-
-
-===================
-CPU OPERATING MODES
-===================
-
-The FR-V CPU has three basic operating modes. In order of increasing
-capability:
-
-  (1) User mode.
-
-      Basic userspace running mode.
-
-  (2) Kernel mode.
-
-      Normal kernel mode. There are many additional control registers
-      available that may be accessed in this mode, in addition to all the
-      stuff available to user mode. This has two submodes:
-
-      (a) Exceptions enabled (PSR.T == 1).
-
-	  Exceptions will invoke the appropriate normal kernel mode
-	  handler. On entry to the handler, the PSR.T bit will be cleared.
-
-      (b) Exceptions disabled (PSR.T == 0).
-
-	  No exceptions or interrupts may happen. Any mandatory exceptions
-	  will cause the CPU to halt unless the CPU is told to jump into
-	  debug mode instead.
-
-  (3) Debug mode.
-
-      No exceptions may happen in this mode. Memory protection and
-      management exceptions will be flagged for later consideration, but
-      the exception handler won't be invoked. Debugging traps such as
-      hardware breakpoints and watchpoints will be ignored. This mode is
-      entered only by debugging events obtained from the other two modes.
-
-      All kernel mode registers may be accessed, plus a few extra debugging
-      specific registers.
-
-
-=================================
-INTERNAL KERNEL-MODE REGISTER ABI
-=================================
-
-There are a number of permanent register assignments that are set up by
-entry.S in the exception prologue. Note that there is a complete set of
-exception prologues for each of user->kernel transition and kernel->kernel
-transition. There are also user->debug and kernel->debug mode transition
-prologues.
-
-
-	REGISTER	FLAVOUR	USE
-	===============	=======	==============================================
-	GR1			Supervisor stack pointer
-	GR15			Current thread info pointer
-	GR16			GP-Rel base register for small data
-	GR28			Current exception frame pointer (__frame)
-	GR29			Current task pointer (current)
-	GR30			Destroyed by kernel mode entry
-	GR31		NOMMU	Destroyed by debug mode entry
-	GR31		MMU	Destroyed by TLB miss kernel mode entry
-	CCR.ICC2		Virtual interrupt disablement tracking
-	CCCR.CC3		Cleared by exception prologue 
-				(atomic op emulation)
-	SCR0		MMU	See mmu-layout.txt.
-	SCR1		MMU	See mmu-layout.txt.
-	SCR2		MMU	Save for EAR0 (destroyed by icache insns 
-					       in debug mode)
-	SCR3		MMU	Save for GR31 during debug exceptions
-	DAMR/IAMR	NOMMU	Fixed memory protection layout.
-	DAMR/IAMR	MMU	See mmu-layout.txt.
-
-
-Certain registers are also used or modified across function calls:
-
-	REGISTER	CALL				RETURN
-	===============	===============================	======================
-	GR0		Fixed Zero			-
-	GR2		Function call frame pointer
-	GR3		Special				Preserved
-	GR3-GR7		-				Clobbered
-	GR8		Function call arg #1		Return value 
-							(or clobbered)
-	GR9		Function call arg #2		Return value MSW 
-							(or clobbered)
-	GR10-GR13	Function call arg #3-#6		Clobbered
-	GR14		-				Clobbered
-	GR15-GR16	Special				Preserved
-	GR17-GR27	-				Preserved
-	GR28-GR31	Special				Only accessed 
-							explicitly
-	LR		Return address after CALL	Clobbered
-	CCR/CCCR	-				Mostly Clobbered
-
-
-================================
-INTERNAL DEBUG-MODE REGISTER ABI
-================================
-
-This is the same as the kernel-mode register ABI for functions calls. The
-difference is that in debug-mode there's a different stack and a different
-exception frame. Almost all the global registers from kernel-mode
-(including the stack pointer) may be changed.
-
-	REGISTER	FLAVOUR	USE
-	===============	=======	==============================================
-	GR1			Debug stack pointer
-	GR16			GP-Rel base register for small data
-	GR31			Current debug exception frame pointer 
-				(__debug_frame)
-	SCR3		MMU	Saved value of GR31
-
-
-Note that debug mode is able to interfere with the kernel's emulated atomic
-ops, so it must be exceedingly careful not to do any that would interact
-with the main kernel in this regard. Hence the debug mode code (gdbstub) is
-almost completely self-contained. The only external code used is the
-sprintf family of functions.
-
-Furthermore, break.S is so complicated because single-step mode does not
-switch off on entry to an exception. That means unless manually disabled,
-single-stepping will blithely go on stepping into things like interrupts.
-See gdbstub.txt for more information.
-
-
-==========================
-VIRTUAL INTERRUPT HANDLING
-==========================
-
-Because accesses to the PSR is so slow, and to disable interrupts we have
-to access it twice (once to read and once to write), we don't actually
-disable interrupts at all if we don't have to. What we do instead is use
-the ICC2 condition code flags to note virtual disablement, such that if we
-then do take an interrupt, we note the flag, really disable interrupts, set
-another flag and resume execution at the point the interrupt happened.
-Setting condition flags as a side effect of an arithmetic or logical
-instruction is really fast. This use of the ICC2 only occurs within the
-kernel - it does not affect userspace.
-
-The flags we use are:
-
- (*) CCR.ICC2.Z [Zero flag]
-
-     Set to virtually disable interrupts, clear when interrupts are
-     virtually enabled. Can be modified by logical instructions without
-     affecting the Carry flag.
-
- (*) CCR.ICC2.C [Carry flag]
-
-     Clear to indicate hardware interrupts are really disabled, set otherwise.
-
-
-What happens is this:
-
- (1) Normal kernel-mode operation.
-
-	ICC2.Z is 0, ICC2.C is 1.
-
- (2) An interrupt occurs. The exception prologue examines ICC2.Z and
-     determines that nothing needs doing. This is done simply with an
-     unlikely BEQ instruction.
-
- (3) The interrupts are disabled (local_irq_disable)
-
-	ICC2.Z is set to 1.
-
- (4) If interrupts were then re-enabled (local_irq_enable):
-
-	ICC2.Z would be set to 0.
-
-     A TIHI #2 instruction (trap #2 if condition HI - Z==0 && C==0) would
-     be used to trap if interrupts were now virtually enabled, but
-     physically disabled - which they're not, so the trap isn't taken. The
-     kernel would then be back to state (1).
-
- (5) An interrupt occurs. The exception prologue examines ICC2.Z and
-     determines that the interrupt shouldn't actually have happened. It
-     jumps aside, and there disabled interrupts by setting PSR.PIL to 14
-     and then it clears ICC2.C.
-
- (6) If interrupts were then saved and disabled again (local_irq_save):
-
-	ICC2.Z would be shifted into the save variable and masked off 
-	(giving a 1).
-
-	ICC2.Z would then be set to 1 (thus unchanged), and ICC2.C would be
-	unaffected (ie: 0).
-
- (7) If interrupts were then restored from state (6) (local_irq_restore):
-
-	ICC2.Z would be set to indicate the result of XOR'ing the saved
-	value (ie: 1) with 1, which gives a result of 0 - thus leaving
-	ICC2.Z set.
-
-	ICC2.C would remain unaffected (ie: 0).
-
-     A TIHI #2 instruction would be used to again assay the current state,
-     but this would do nothing as Z==1.
-
- (8) If interrupts were then enabled (local_irq_enable):
-
-	ICC2.Z would be cleared. ICC2.C would be left unaffected. Both
-	flags would now be 0.
-
-     A TIHI #2 instruction again issued to assay the current state would
-     then trap as both Z==0 [interrupts virtually enabled] and C==0
-     [interrupts really disabled] would then be true.
-
- (9) The trap #2 handler would simply enable hardware interrupts 
-     (set PSR.PIL to 0), set ICC2.C to 1 and return.
-
-(10) Immediately upon returning, the pending interrupt would be taken.
-
-(11) The interrupt handler would take the path of actually processing the
-     interrupt (ICC2.Z is clear, BEQ fails as per step (2)).
-
-(12) The interrupt handler would then set ICC2.C to 1 since hardware
-     interrupts are definitely enabled - or else the kernel wouldn't be here.
-
-(13) On return from the interrupt handler, things would be back to state (1).
-
-This trap (#2) is only available in kernel mode. In user mode it will
-result in SIGILL.

-			==========================
-			KERNEL ABIS FOR METAG ARCH
-			==========================
-
-This document describes the Linux ABIs for the metag architecture, and has the
-following sections:
-
- (*) Outline of registers
- (*) Userland registers
- (*) Kernel registers
- (*) System call ABI
- (*) Calling conventions
-
-
-====================
-OUTLINE OF REGISTERS
-====================
-
-The main Meta core registers are arranged in units:
-
-	UNIT	Type	DESCRIPTION	GP	EXT	PRIV	GLOBAL
-	=======	=======	===============	=======	=======	=======	=======
-	CT	Special	Control unit
-	D0	General	Data unit 0	0-7	8-15	16-31	16-31
-	D1	General	Data unit 1	0-7	8-15	16-31	16-31
-	A0	General	Address unit 0	0-3	4-7	 8-15	 8-15
-	A1	General	Address unit 1	0-3	4-7	 8-15	 8-15
-	PC	Special	PC unit		0		 1
-	PORT	Special	Ports
-	TR	Special	Trigger unit			 0-7
-	TT	Special	Trace unit			 0-5
-	FX	General	FP unit			0-15
-
-GP registers form part of the main context.
-
-Extended context registers (EXT) may not be present on all hardware threads and
-can be context switched if support is enabled and the appropriate bits are set
-in e.g. the D0.8 register to indicate what extended state to preserve.
-
-Global registers are shared between threads and are privilege protected.
-
-See arch/metag/include/asm/metag_regs.h for definitions relating to core
-registers and the fields and bits they contain. See the TRMs for further details
-about special registers.
-
-Several special registers are preserved in the main context, these are the
-interesting ones:
-
-	REG	(ALIAS)		PURPOSE
-	=======================	===============================================
-	CT.1	(TXMODE)	Processor mode bits (particularly for DSP)
-	CT.2	(TXSTATUS)	Condition flags and LSM_STEP (MGET/MSET step)
-	CT.3	(TXRPT)		Branch repeat counter
-	PC.0	(PC)		Program counter
-
-Some of the general registers have special purposes in the ABI and therefore
-have aliases:
-
-	D0 REG	(ALIAS)	PURPOSE		D1 REG	(ALIAS)	PURPOSE
-	===============	===============	===============	=======================
-	D0.0	(D0Re0)	32bit result	D1.0	(D1Re0)	Top half of 64bit result
-	D0.1	(D0Ar6)	Argument 6	D1.1	(D1Ar5)	Argument 5
-	D0.2	(D0Ar4)	Argument 4	D1.2	(D1Ar3)	Argument 3
-	D0.3	(D0Ar2)	Argument 2	D1.3	(D1Ar1)	Argument 1
-	D0.4	(D0FrT)	Frame temp	D1.4	(D1RtP)	Return pointer
-	D0.5		Call preserved	D1.5		Call preserved
-	D0.6		Call preserved	D1.6		Call preserved
-	D0.7		Call preserved	D1.7		Call preserved
-
-	A0 REG	(ALIAS)	PURPOSE		A1 REG	(ALIAS)	PURPOSE
-	===============	===============	===============	=======================
-	A0.0	(A0StP)	Stack pointer	A1.0	(A1GbP)	Global base pointer
-	A0.1	(A0FrP)	Frame pointer	A1.1	(A1LbP)	Local base pointer
-	A0.2				A1.2
-	A0.3				A1.3
-
-
-==================
-USERLAND REGISTERS
-==================
-
-All the general purpose D0, D1, A0, A1 registers are preserved when entering the
-kernel (including asynchronous events such as interrupts and timer ticks) except
-the following which have special purposes in the ABI:
-
-	REGISTERS	WHEN	STATUS		PURPOSE
-	===============	=======	===============	===============================
-	D0.8		DSP	Preserved	ECH, determines what extended
-						DSP state to preserve.
-	A0.0	(A0StP)	ALWAYS	Preserved	Stack >= A0StP may be clobbered
-						at any time by the creation of a
-						signal frame.
-	A1.0	(A1GbP)	SMP	Clobbered	Used as temporary for loading
-						kernel stack pointer and saving
-						core context.
-	A0.15		!SMP	Protected	Stores kernel stack pointer.
-	A1.15		ALWAYS	Protected	Stores kernel base pointer.
-
-On UP A0.15 is used to store the kernel stack pointer for storing the userland
-context. A0.15 is global between hardware threads though which means it cannot
-be used on SMP for this purpose. Since no protected local registers are
-available A1GbP is reserved for use as a temporary to allow a percpu stack
-pointer to be loaded for storing the rest of the context.
-
-
-================
-KERNEL REGISTERS
-================
-
-When in the kernel the following registers have special purposes in the ABI:
-
-	REGISTERS	WHEN	STATUS		PURPOSE
-	===============	=======	===============	===============================
-	A0.0	(A0StP)	ALWAYS	Preserved	Stack >= A0StP may be clobbered
-						at any time by the creation of
-						an irq signal frame.
-	A1.0	(A1GbP)	ALWAYS	Preserved	Reserved (kernel base pointer).
-
-
-===============
-SYSTEM CALL ABI
-===============
-
-When a system call is made, the following registers are effective:
-
-	REGISTERS	CALL			RETURN
-	===============	=======================	===============================
-	D0.0	(D0Re0)				Return value (or -errno)
-	D1.0	(D1Re0)	System call number	Clobbered
-	D0.1	(D0Ar6)	Syscall arg #6		Preserved
-	D1.1	(D1Ar5)	Syscall arg #5		Preserved
-	D0.2	(D0Ar4)	Syscall arg #4		Preserved
-	D1.2	(D1Ar3)	Syscall arg #3		Preserved
-	D0.3	(D0Ar2)	Syscall arg #2		Preserved
-	D1.3	(D1Ar1)	Syscall arg #1		Preserved
-
-Due to the limited number of argument registers and some system calls with badly
-aligned 64-bit arguments, 64-bit values are always packed in consecutive
-arguments, even if this is contrary to the normal calling conventions (where the
-two halves would go in a matching pair of data registers).
-
-For example fadvise64_64 usually has the signature:
-
-	long sys_fadvise64_64(i32 fd, i64 offs, i64 len, i32 advice);
-
-But for metag fadvise64_64 is wrapped so that the 64-bit arguments are packed:
-
-	long sys_fadvise64_64_metag(i32 fd,      i32 offs_lo,
-				    i32 offs_hi, i32 len_lo,
-				    i32 len_hi,  i32 advice)
-
-So the arguments are packed in the registers like this:
-
-	D0 REG	(ALIAS)	VALUE		D1 REG	(ALIAS)	VALUE
-	===============	===============	===============	=======================
-	D0.1	(D0Ar6)	advice		D1.1	(D1Ar5)	hi(len)
-	D0.2	(D0Ar4)	lo(len)		D1.2	(D1Ar3)	hi(offs)
-	D0.3	(D0Ar2)	lo(offs)	D1.3	(D1Ar1)	fd
-
-
-===================
-CALLING CONVENTIONS
-===================
-
-These calling conventions apply to both user and kernel code. The stack grows
-from low addresses to high addresses in the metag ABI. The stack pointer (A0StP)
-should always point to the next free address on the stack and should at all
-times be 64-bit aligned. The following registers are effective at the point of a
-call:
-
-	REGISTERS	CALL			RETURN
-	===============	=======================	===============================
-	D0.0	(D0Re0)				32bit return value
-	D1.0	(D1Re0)				Upper half of 64bit return value
-	D0.1	(D0Ar6)	32bit argument #6	Clobbered
-	D1.1	(D1Ar5)	32bit argument #5	Clobbered
-	D0.2	(D0Ar4)	32bit argument #4	Clobbered
-	D1.2	(D1Ar3)	32bit argument #3	Clobbered
-	D0.3	(D0Ar2)	32bit argument #2	Clobbered
-	D1.3	(D1Ar1)	32bit argument #1	Clobbered
-	D0.4	(D0FrT)				Clobbered
-	D1.4	(D1RtP)	Return pointer		Clobbered
-	D{0-1}.{5-7}				Preserved
-	A0.0	(A0StP)	Stack pointer		Preserved
-	A1.0	(A0GbP)				Preserved
-	A0.1	(A0FrP)	Frame pointer		Preserved
-	A1.1	(A0LbP)				Preserved
-	A{0-1},{2-3}				Clobbered
-
-64-bit arguments are placed in matching pairs of registers (i.e. the same
-register number in both D0 and D1 units), with the least significant half in D0
-and the most significant half in D1, leaving a gap where necessary. Further
-arguments are stored on the stack in reverse order (earlier arguments at higher
-addresses):
-
-	ADDRESS		0     1     2     3	4     5     6     7
-	===============	===== ===== ===== =====	===== ===== ===== =====
-	A0StP       -->
-	A0StP-0x08	32bit argument #8	32bit argument #7
-	A0StP-0x10	32bit argument #10	32bit argument #9
-
-Function prologues tend to look a bit like this:
-
-	/* If frame pointer in use, move it to frame temp register so it can be
-	   easily pushed onto stack */
-	MOV	D0FrT,A0FrP
-
-	/* If frame pointer in use, set it to stack pointer */
-	ADD	A0FrP,A0StP,#0
-
-	/* Preserve D0FrT, D1RtP, D{0-1}.{5-7} on stack, incrementing A0StP */
-	MSETL	[A0StP++],D0FrT,D0.5,D0.6,D0.7
-
-	/* Allocate some stack space for local variables */
-	ADD	A0StP,A0StP,#0x10
-
-At this point the stack would look like this:
-
-	ADDRESS		0     1     2     3	4     5     6     7
-	===============	===== ===== ===== =====	===== ===== ===== =====
-	A0StP       -->

-	A0StP-0x10
-	A0StP-0x18	Old D0.7		Old D1.7
-	A0StP-0x20	Old D0.6		Old D1.6
-	A0StP-0x28	Old D0.5		Old D1.5
-	A0FrP       -->	Old A0FrP (frame ptr)	Old D1RtP (return ptr)
-	A0FrP-0x08	32bit argument #8	32bit argument #7
-	A0FrP-0x10	32bit argument #10	32bit argument #9
-
-Function epilogues tend to differ depending on the use of a frame pointer. An
-example of a frame pointer epilogue:
-
-	/* Restore D0FrT, D1RtP, D{0-1}.{5-7} from stack, incrementing A0FrP */
-	MGETL	D0FrT,D0.5,D0.6,D0.7,[A0FrP++]
-	/* Restore stack pointer to where frame pointer was before increment */
-	SUB	A0StP,A0FrP,#0x20
-	/* Restore frame pointer from frame temp */
-	MOV	A0FrP,D0FrT
-	/* Return to caller via restored return pointer */
-	MOV	PC,D1RtP
-
-If the function hasn't touched the frame pointer, MGETL cannot be safely used
-with A0StP as it always increments and that would expose the stack to clobbering
-by interrupts (kernel) or signals (user). Therefore it's common to see the MGETL
-split into separate GETL instructions:
-
-	/* Restore D0FrT, D1RtP, D{0-1}.{5-7} from stack */
-	GETL	D0FrT,D1RtP,[A0StP+#-0x30]
-	GETL	D0.5,D1.5,[A0StP+#-0x28]
-	GETL	D0.6,D1.6,[A0StP+#-0x20]
-	GETL	D0.7,D1.7,[A0StP+#-0x18]
-	/* Restore stack pointer */
-	SUB	A0StP,A0StP,#0x30
-	/* Return to caller via restored return pointer */
-	MOV	PC,D1RtP

Documentation/mn10300/ABI.txt

-			   =========================
-			   MN10300 FUNCTION CALL ABI
-			   =========================
-
-=======
-GENERAL
-=======
-
-The MN10300/AM33 kernel runs in little-endian mode; big-endian mode is not
-supported.
-
-The stack grows downwards, and should always be 32-bit aligned. There are
-separate stack pointer registers for userspace and the kernel.
-
-
-================
-ARGUMENT PASSING
-================
-
-The first two arguments (assuming up to 32-bits per argument) to a function are
-passed in the D0 and D1 registers respectively; all other arguments are passed
-on the stack.
-
-If 64-bit arguments are being passed, then they are never split between
-registers and the stack. If the first argument is a 64-bit value, it will be
-passed in D0:D1. If the first argument is not a 64-bit value, but the second
-is, the second will be passed entirely on the stack and D1 will be unused.
-
-Arguments smaller than 32-bits are not coalesced within a register or a stack
-word. For example, two byte-sized arguments will always be passed in separate
-registers or word-sized stack slots.
-
-
-=================
-CALLING FUNCTIONS
-=================
-
-The caller must allocate twelve bytes on the stack for the callee's use before
-it inserts a CALL instruction. The CALL instruction will write into the TOS
-word, but won't actually modify the stack pointer; similarly, the RET
-instruction reads from the TOS word of the stack, but doesn't move the stack
-pointer beyond it.
-
-
-	Stack:
-	|		|
-	|		|
-	|---------------| SP+20
-	| 4th Arg	|
-	|---------------| SP+16
-	| 3rd Arg	|
-	|---------------| SP+12
-	| D1 Save Slot	|
-	|---------------| SP+8
-	| D0 Save Slot	|
-	|---------------| SP+4
-	| Return Addr	|
-	|---------------| SP
-	|		|
-	|		|
-
-
-The caller must leave space on the stack (hence an allocation of twelve bytes)
-in which the callee may store the first two arguments.
-
-
-============
-RETURN VALUE
-============
-
-The return value is passed in D0 for an integer (or D0:D1 for a 64-bit value),
-or A0 for a pointer.
-
-If the return value is a value larger than 64-bits, or is a structure or an
-array, then a hidden first argument will be passed to the callee by the caller:
-this will point to a piece of memory large enough to hold the result of the
-function. In this case, the callee will return the value in that piece of
-memory, and no value will be returned in D0 or A0.
-
-
-===================
-REGISTER CLOBBERING
-===================
-
-The values in certain registers may be clobbered by the callee, and other
-values must be saved:
-
-	Clobber:	D0-D1, A0-A1, E0-E3
-	Save:		D2-D3, A2-A3, E4-E7, SP
-
-All other non-supervisor-only registers are clobberable (such as MDR, MCRL,
-MCRH).
-
-
-=================
-SPECIAL REGISTERS
-=================
-
-Certain ordinary registers may carry special usage for the compiler:
-
-	A3:	Frame pointer
-	E2:	TLS pointer
-
-
-==========
-KERNEL ABI
-==========
-
-The kernel may use a slightly different ABI internally.
-
- (*) E2
-
-     If CONFIG_MN10300_CURRENT_IN_E2 is defined, then the current task pointer
-     will be kept in the E2 register, and that register will be marked
-     unavailable for the compiler to use as a scratch register.
-
-     Normally the kernel uses something like:
-
-	MOV	SP,An
-	AND	0xFFFFE000,An
-	MOV	(An),Rm		// Rm holds current
-	MOV	(yyy,Rm)	// Access current->yyy
-
-     To find the address of current; but since this option permits current to
-     be carried globally in an register, it can use:
-
-	MOV	(yyy,E2)	// Access current->yyy
-
-     instead.
-
-
-===============
-SYSTEM CALL ABI
-===============
-
-System calls are called with the following convention:
-
-	REGISTER	ENTRY			EXIT
-	===============	=======================	=======================
-	D0		Syscall number		Return value
-	A0		1st syscall argument	Saved
-	D1		2nd syscall argument	Saved
-	A3		3rd syscall argument	Saved
-	A2		4th syscall argument	Saved
-	D3		5th syscall argument	Saved
-	D2		6th syscall argument	Saved
-
-All other registers are saved.  The layout is a consequence of the way the MOVM
-instruction stores registers onto the stack.

Documentation/mn10300/compartmentalisation.txt

-		   =========================================
-		   PART-SPECIFIC SOURCE COMPARTMENTALISATION
-		   =========================================
-
-The sources for various parts are compartmentalised at two different levels:
-
- (1) Processor level
-
-     The "processor level" is a CPU core plus the other on-silicon
-     peripherals.
-
-     Processor-specific header files are divided among directories in a similar
-     way to the CPU level:
-
-	(*) include/asm-mn10300/proc-mn103e010/
-
-	    Support for the AM33v2 CPU core.
-
-     The appropriate processor is selected by a CONFIG_MN10300_PROC_YYYY option
-     from the "Processor support" choice menu in the arch/mn10300/Kconfig file.
-
-
- (2) Unit level
-
-     The "unit level" is a processor plus all the external peripherals
-     controlled by that processor.
-
-     Unit-specific header files are divided among directories in a similar way
-     to the CPU level; not only that, but specific sources may also be
-     segregated into separate directories under the arch directory:
-
-	(*) include/asm-mn10300/unit-asb2303/
-	(*) arch/mn10300/unit-asb2303/
-
-	    Support for the ASB2303 board with an ASB2308 daughter board.
-
-	(*) include/asm-mn10300/unit-asb2305/
-	(*) arch/mn10300/unit-asb2305/
-
-	    Support for the ASB2305 board.
-
-     The appropriate processor is selected by a CONFIG_MN10300_UNIT_ZZZZ option
-     from the "Unit type" choice menu in the arch/mn10300/Kconfig file.
-
-
-============
-COMPILE TIME
-============
-
-When the kernel is compiled, symbolic links will be made in the asm header file
-directory for this arch:
-
-	include/asm-mn10300/proc => include/asm-mn10300/proc-YYYY/
-	include/asm-mn10300/unit => include/asm-mn10300/unit-ZZZZ/
-
-So that the header files contained in those directories can be accessed without
-lots of #ifdef-age.
-
-The appropriate arch/mn10300/unit-ZZZZ directory will also be entered by the
-compilation process; all other unit-specific directories will be ignored.

-	  By default, the Blackfin hardware errors are not exact - the error

-	  can cause the wrong application, or even the kernel to receive a

-	  If an exception is caused while executing code within the exception

-	  a double fault occurs. On the Blackfin, this is a unrecoverable
-	  event. You have two options:
-	  - RESET exactly when double fault occurs. The excepting
-	    instruction address is stored in RETX, where the next kernel
-	    boot will print it out.
-	  - Print debug message. This is much more error prone, although
-	    easier to handle. It is error prone since:
-	    - The excepting instruction is not committed.
-	    - All writebacks from the instruction are prevented.
-	    - The generated exception is not taken.
-	    - The EXCAUSE field is updated with an unrecoverable event
-	    The only way to check this is to see if EXCAUSE contains the
-	    unrecoverable event value at every exception return. By selecting
-	    this option, you are skipping over the faulting instruction, and 
-	    hoping things stay together enough to print out a debug message.
-

-	bool "Turn on Blackfin's Hardware Trace"
-	default y
-	help
-	  All Blackfins include a Trace Unit which stores a history of the last
-	  16 changes in program flow taken by the program sequencer. The history
-	  allows the user to recreate the program sequencer’s recent path. This
-	  can be handy when an application dies - we print out the execution
-	  path of how it got to the offending instruction.
-
-	  By turning this off, you may save a tiny amount of power.

-	prompt "Omit loop Tracing"
-	default DEBUG_BFIN_HWTRACE_COMPRESSION_OFF
-	depends on DEBUG_BFIN_HWTRACE_ON
-	help
-	  The trace buffer can be configured to omit recording of changes in
-	  program flow that match either the last entry or one of the last
-	  two entries. Omitting one of these entries from the record prevents
-	  the trace buffer from overflowing because of any sort of loop (for, do
-	  while, etc) in the program.
-
-	  Because zero-overhead Hardware loops are not recorded in the trace buffer,
-	  this feature can be used to prevent trace overflow from loops that
-	  are nested four deep.
-

-	depends on DEBUG_BFIN_HWTRACE_ON
-	default n
-	help
-	  By selecting this option, every time the 16 hardware entries in
-	  the Blackfin's HW Trace buffer are full, the kernel will move them
-	  into a software buffer, for dumping when there is an issue. This 
-	  has a great impact on performance, (an interrupt every 16 change of 
-	  flows) and should normally be turned off, except in those nasty
-	  debugging sessions

-	depends on DEBUG_BFIN_HWTRACE_ON
-	default y
-	help
-	  The CPLB error handler contains a lot of flow changes which can
-	  quickly fill up the hardware trace buffer.  When debugging crashes,
-	  the hardware trace may indicate that the problem lies in kernel
-	  space when in reality an application is buggy.
-
-	  Say Y here to disable hardware tracing in some known "jumpy" pieces
-	  of code so that the trace buffer will extend further back.
-
-config EARLY_PRINTK
-	bool "Early printk" 
-	default n
-	select SERIAL_CORE_CONSOLE
-	help
-	  This option enables special console drivers which allow the kernel
-	  to print messages very early in the bootup process.
-
-	  This is useful for kernel debugging when your machine crashes very
-	  early before the console code is initialized. After enabling this
-	  feature, you must add "earlyprintk=serial,uart0,57600" to the
-	  command line (bootargs). It is safe to say Y here in all cases, as
-	  all of this lives in the init section and is thrown away after the
-	  kernel boots completely.
-
-config NMI_WATCHDOG

-	help
-	  If any CPU in the system does not execute the period local timer

-	  information. This information can be used to debug the lockup.

-config ACCESS_CHECK

-
-config BFIN_ISRAM_SELF_TEST
-	bool "isram boot self tests"

-	  Run some self tests of the isram driver code at boot.
-
-config BFIN_PSEUDODBG_INSNS
-	bool "Support pseudo debug instructions"
-	default n
-	help
-	  This option allows the kernel to emulate some pseudo instructions which
-	  allow simulator test cases to be run under Linux with no changes.
-
-	  Most people should say N here.
-
-config BFIN_PM_WAKEUP_TIME_BENCH
-	bool "Display the total time for kernel to resume from power saving mode"
