SubjectRe: [PATCH V2 5/6] x86: add CONFIG_ARM_AMBA, selected by STA2X11

Ok. This is my summary of the compilation errors I have when
enabling ARM_AMBA undex x86 and enabling everything that appears
in "make oldconfig":

This is a sum up of the errors in all driver that are
enabled by telling "CONFIG_ARM_AMBA=y" in the x86 config.

drivers/dma/pl330.c: register names conflict with arch symbols
proposed fix: use proper prefix names

drivers/dma/amba-pl08x.c: needs <asm/hardware/pl080.h>
proposed fix: move pl080.h to include/linux

drivers/gpio/gpio-pl061.c: uses chained_irq_enter/exit
proposed fix: depend on CONFIG_ARM (the function only exists in arm)

drivers/mmc/host/mmci.c: uses <asm/sizes.h>
drivers/mmc/host/mmci.c: uses readsl/writesl
proposed fix: use linux/sizes.h and provide readsl/writesl like others do

drivers/spi/spi-pl022.c: warning for an integer size mismatch
proposed fix: none by now

drivers/watchdog/sp805_wdt.c: uses writel_relaxed
proposed fix: depend on CONFIG_ARM (this is a spear-only cell by now)

So, if you agree, I would:

- fix the two dma engines (checking pl080 against russell's pending

- make pl061 and sp805_wdt.c depends on CONFIG_ARM

- temporarily do the same for mmci, which I'll make work soon as
I have it under my pci bridge

- ignore the warning on spi-pl022 until I find a fix

- resubmit my enabling of arm_amba for x86 and my pci-to-amba bridge
