The RAM_SIZE macro in mach/hardware.h conflicts with macros of
the same name in multiple drivers, leading to annoying build warnings:
In file included from drivers/net/ethernet/cirrus/cs89x0.c:79:0:
drivers/net/ethernet/cirrus/cs89x0.h:324:0: error: "RAM_SIZE" redefined [-Werror]
#define RAM_SIZE 0x1000 /* The card has 4k bytes or RAM */
^

arch/arm/mach-rpc/include/mach/hardware.h:28:0: note: this is the location of the previous definition
#define RAM_SIZE 0x10000000
We don't use RAM_SIZE/RAM_START at all, so we could just remove
them, but it might be nice to leave them for documentation purposes,
so this renames them to RPC_RAM_SIZE/RPC_RAM_START in order to
avoid the build warnings

Document the UNCACHEABLE_ADDR definitions for footbridge and SA1100
so that we know where they're located and/or what they're accessing.
Change RiscPC to calculate the UNCACHEABLE_ADDR value from FLUSH_BASE
as that's where we locate that.
UNCACHEABLE_ADDR is used to perform an uncached access (ARMv4
terminology) necessary to force a CPU clock-switch to the memory-
speed clock, as required for entering WFI.

Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

Remove ioaddr() usage from ecard.c, updating (and renaming) the
constants in RiscPC's hardware.h to contain the proper translation.
As this gets rid of the last ioaddr() usage, kill that too.

This just leaves include/asm-arm/plat-* to deal with.
