As Russell's suggested, the SCU registers can be mapped to 0xffff1000 with single page. Beause the mapping is not a fix map, and i can not use the static functions in arch/arm/mm/mm.h, I still have to use static mapping for SCU registers by iotable_init. So what is your idea about how to make the SCU registers mapping to be a peice of common code?
