ARM: S3C: Update CPU register mapping practices.
Currently map-base.h defines the main virtual address mappings made for all the support S3C SoC series, but does not then define any base for per-cpu mappings to be made from. Add S3C_ADDR_CPU() macro to define an virtual address as an offset from the last of the core mappings. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
