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 */ ^ In file included from /git/arm-soc/arch/arm/mach-rpc/include/mach/io.h:16:0, from /git/arm-soc/arch/arm/include/asm/io.h:194, from /git/arm-soc/include/linux/scatterlist.h:8, from /git/arm-soc/include/linux/dmaengine.h:24, from /git/arm-soc/include/linux/netdevice.h:38, from /git/arm-soc/drivers/net/ethernet/cirrus/cs89x0.c:54: 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
