We need to add plat-s3c to the build to get the headers that will go in here once moved from include/asm-arm so we may as well put some useful common s3c code in here to stop the errors generated form having nothing built. The cpu setup is now passed the cpu idcode and the table of supported cpus to s3c_init_cpu() to abstract the cpu identification out of the initial io setup. As well as moving the cpu initialisation code, we move the map of the board specific items up to the calling code as none of the map_io() functions actually do anything other than pass this to iotable_init(). This patch does not rename any of the init functions that will be common to s3c24xx and any other s3c architectures as this can be done at a later date as it will touch all the board support files which use functions such as s3c24xx_init_clocks() and s3c24xx_init_uarts(). Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h still has functions that are used by both the cpu and board initialisation functions. This means that each board has definitions specific to the cpu support included and the vice-versa. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
