-Overview of Kbuild Commands
-24 January 1999
-Michael Elizabeth Chastain, <mailto:mec@shout.net>
-
-
-
-=== Introduction
-
-Someday we'll get our arms around all this stuff and clean it up
-a little!  Meanwhile, this file describes the system as it is today.
-
-
-
-=== Quick Start
-
-If you are building a kernel for the first time, here are the commands
-you need:
-
-    make config
-    make dep
-    make bzImage
-
-Instead of 'make config', you can run 'make menuconfig' for a full-screen
-text interface, or 'make xconfig' for an X interface using TCL/TK.
-
-'make bzImage' will leave your new kernel image in arch/i386/boot/bzImage.
-You can also use 'make bzdisk' or 'make bzlilo'.
-
-See the lilo documentation for more information on how to use lilo.
-You can also use the 'loadlin' program to boot Linux from MS-DOS.
-
-Some computers won't work with 'make bzImage', either due to hardware
-problems or very old versions of lilo or loadlin.  If your kernel image
-is small, you may use 'make zImage', 'make zdisk', or 'make zlilo'
-on theses systems.
-
-If you find a file name 'vmlinux' in the top directory of the source tree,
-just ignore it.  This is an intermediate file and you can't boot from it.
-
-Other architectures: the information above is oriented towards the
-i386.  On other architectures, there are no 'bzImage' files; simply
-use 'zImage' or 'vmlinux' as appropriate for your architecture.
-
-Note: the difference between 'zImage' files and 'bzImage' files is that
-'bzImage' uses a different layout and a different loading algorithm,
-and thus has a larger capacity.  Both files use gzip compression.
-The 'bz' in 'bzImage' stands for 'big zImage', not for 'bzip'!
-
-
-
-=== Top Level Makefile targets
-
-Here are the targets available at the top level:
-
-    make config, make oldconfig, make menuconfig, make xconfig
-
-	Configure the Linux kernel.  You must do this before almost
-	anything else.
-
-	config		line-oriented interface
-	oldconfig	line-oriented interface, re-uses old values
-	menuconfig	curses-based full-screen interface
-	xconfig		X window system interface
-
-    make checkconfig
-
-	This runs a little perl script that checks the source tree for
-	missing instances of #include <linux/config.h>.  Someone needs to
-	do this occasionally, because the C preprocessor will silently give
-	bad results if these symbols haven't been included (it treats
-	undefined symbols in preprocessor directives as defined to 0).
-	Superfluous uses of #include <linux/config.h> are also reported,
-	but you can ignore these, because smart CONFIG_* dependencies
-	make them harmless.
-
-	You can run 'make checkconfig' without configuring the kernel.
-	Also, 'make checkconfig' does not modify any files.
-
-    make checkhelp
-
-	This runs another little perl script that checks the source tree
-	for options that are in Config.in files but are not documented
-	in scripts/Configure.help.  Again, someone needs to do this
-	occasionally.  If you are adding configuration options, it's
-	nice if you do it before you publish your patch!
-
-	You can run 'make checkhelp' without configuring the kernel.
-	Also, 'make checkhelp' does not modify any files.
-
-    make dep, make depend
-
-	'make dep' is a synonym for the long form, 'make depend'.
-
-	This command does two things.  First, it computes dependency
-	information about which .o files depend on which .h files.
-	It records this information in a top-level file named .hdepend
-	and in one file per source directory named .depend.
-
-	Second, if you have CONFIG_MODVERSIONS enabled, 'make dep'
-	computes symbol version information for all of the files that
-	export symbols (note that both resident and modular files may
-	export symbols).
-
-	If you do not enable CONFIG_MODVERSIONS, you only have to run
-	'make dep' once, right after the first time you configure
-	the kernel.  The .hdepend files and the .depend file are
-	independent of your configuration.
-
-	If you do enable CONFIG_MODVERSIONS, you must run 'make dep'
-	every time you change your configuration, because the module
-	symbol version information depends on the configuration.
-
-[to be continued ...]

-  allno		reply 'n' to all options, minimal kernel.

-
-
-All random configurations will satisfy the config rules, that is, all
-configurations should be valid.  Any build errors indicate bugs in the
-config dependency rules or in the Makefiles.
-
-You can constrain the random configuration, e.g. you may want to force
-the use of modules or the absence of /proc or cramfs must be a module.
-If file .force_default exists then it is read to preset selected
-values, all other values will be randomly selected, subject to the
-config rules.  The syntax of .force_default is:
-
-CONFIG_foo=value
-  Force this value, for example CONFIG_MODULES=y, CONFIG_PROC_FS=n,
-  CONFIG_RAMFS=m.
-
-# CONFIG_foo is not set
-  Equivalent to CONFIG_foo=n, supported because this is the format used
-  in .config.  NOTE: The leading '#' is required.
-
-# list CONFIG_foo val1,val2,val3
-  Pick a value for CONFIG_foo from the list.  CONFIG_foo must be an int
-  or hex option.  NOTE: The leading '#' is required.
-
-# range CONFIG_foo min max
-  Pick a value for CONFIG_foo in the range min <=> max.  CONFIG_foo
-  must be an int option.  NOTE: The leading '#' is required.
-
-If you have repeated settings of the same option in .force_default then
-values take precedence over lists which take precedence over range.
-Within each group the last setting for an option is used.
-
-Answers "randomised" are bool(), tristate(), dep_tristate() and
-choice().  Unless specified in .force_default, int, hex, and string
-options use the default values from config.in.

+  initramfs_data includes the compressed binary that is the
+  filesystem used for early user space.
+  Note: Older versions of "as" (prior to binutils 2.11.90.0.23
+  released on 2001-07-14) dit not support .incbin.
+  If you are forced to use older binutils than that then the
+  following trick can be applied to create the resulting binary:
+
+
+  ld -m elf_i386  --format binary --oformat elf32-i386 -r \
+  -T initramfs_data.scr initramfs_data.cpio.gz -o initramfs_data.o
+   ld -m elf_i386  -r -o built-in.o initramfs_data.o
+
+  initramfs_data.scr looks like this:
+SECTIONS
+{
+       .init.ramfs : { *(.data) }
+}
+
+  The above example is for i386 - the parameters vary from architectures.
+  Eventually look up LDFLAGS_BLOB in an older version of the
+  arch/$(ARCH)/Makefile to see the flags used before .incbin was introduced.
+
+  Using .incbin has the advantage over ld that the correct flags are set
+  in the ELF header, as required by certain architectures.
