Replace some instances of smp_llsc_mb() with a new macro smp_mb__before_llsc(). It is used before ll/sc sequences that are documented as needing write barrier semantics. The default implementation of smp_mb__before_llsc() is just smp_llsc_mb(), so there are no changes in semantics. Also simplify definition of smp_mb(), smp_rmb(), and smp_wmb() to be just barrier() in the non-SMP case. Signed-off-by:

Implement reset / poweroff in the board code instead. The peripheral reset code is gone too since YAMON which all in-tree boards use does the same work when it boots. Signed-off-by:

For 64-bit kernels with 64KB pages and two level page tables, there are 42 bits worth of virtual address space This is larger than the 40 bits of virtual address space obtained with the default 4KB Page size and three levels, so there are no draw backs for using two level tables with this configuration.

This patch converts the au1000-eth driver to become a full platform-driver as it ought to be. We now pass PHY-speficic configurations through platform_data but for compatibility the driver still assumes the default settings (search for PHY1 on MAC0) when no platform_data is passed. Tested on my MTX-1 board. Signed-off-by:

This patch makes the board code register the au1000-eth platform device. The au1000-eth platform data can be overriden with the au1xxx_override_eth_cfg function like it has to be done for the Bosporus board which uses a different MAC/PHY setup. Signed-off-by:

Limit the amount of address space claimed for Alchemy serial ports to 0x1000. On the Au1300, ports are only 0x1000 apart, and the registers only extend to 0x110 at most on all supported alchemy models. On the Au1300 the autodetect logic no longer works and this makes it necessary to specify the port type through platform data. Because of this the MSR quirk needs to be moved outside the autoconfig() function which will no longer be called when UPF_FIXED_TYPE is specified. Signed-off-by:

Manuel Lauss authored
This patch replaces the general alchemy prom_putchar() implementation in favor of board-specific versions: The UART where the output of prom_putchar is directed to really depends on the board, the current implementation hardcodes this on a per-SoC basis which is just wrong. So a generic uart tx function is provided in the alchemy headers, and the boards can provide their own prom_putchar with custom destination uart, and all in-kernel alchemy boards support early printk.

DMA can only be done from physical addresses; move the "virt_to_phys" source/destination buffer address translation from the dbdma queueing functions (since the hardware can only DMA to/from physical addresses) to their respective users. Signed-off-by:

Remove dbdma compat macros, move remaining users over to default queueing functions and -flags. (Queueing function signature has changed in order to give a build failure instead of silent functional changes due to the no longer implicitly specified DDMA_FLAGS_IE flag) Signed-off-by:

Eliminate the sharing of IRQ names among the differenct Alchemy variants. IRQ numbers need no longer be hidden behind a CONFIG_SOC_AU1XXX symbol: step 1 in my quest to make the Alchemy code less reliant on a hardcoded subtype. This patch also renames the GPIO irq number constants. It's really an interrupt line, NOT a GPIO number! Code which relied on certain irq numbers to have the same name across all supported cpu subtypes is changed to determine current cpu subtype at runtime; in some places this isn't possible so a "compat" symbol is used. Run-tested on DB1200. Signed-off-by:

Manuel Lauss authored
The Alchemy hardware provides a method to prioritize interrupts on a controller by assigning them to a differenct core request line. Assign usb device request interrupt to IC0 Request 0 (which has highest priority in the core and the dispatcher) and others to Request 1. The explicit check for usb device request occurrence should be obsolete now. Signed-off-by:

New PCMCIA socket driver for all Db/Pb1xxx boards (except Pb1000), which replaces au1000_db1x00.c and (most of) au1000_pb1x00.c. Notable improvements: - supports Db1000, DB/PB1100/1500/1550/1200. - support for carddetect and statuschange IRQs. - pcmcia socket mem/io/attr areas and irqs passed through platform resource information. - doesn't freeze system during card insertion/ejection like the one it replaces. - boardtype is automatically detected using BCSR ID register. Run-tested on the DB1200. Cc: Linux-PCMCIA <linux-pcmcia@lists.infradead.org> Signed-off-by: -

remove board_init_irq(): On all in-kernel boards it is sufficient to initialize board interrupts in an arch_initcall by using the default linux irq functions. Some small irqmap.c files have been folded into board_setup files. Run-tested on DB1200; compile-tested on all other affected boards. Signed-off-by:

Manuel Lauss authored
All Alchemy development boards have external CPLDs with a few registers in them. They all share an identical register layout with only a few minor differences (except the PB1000) in bit functions and base addresses. This patch - adds a primitive facility to initialize and use these external registers, - replaces all occurrences of bcsr->xxx accesses with calls to the new functions (the pb1200 cascade irq handling code is special). - collects BCSR register information scattered throughout the board headers in a central place.
