Area for memory controller configuration register space
The address space (0x00000000 ~ 0x0FFFFFFF) is initially allocated to internal or external
PROM for booting procedure, and a special flag is exist in memory controller unit for remapping
lower half space to other type memories. Refer to the description of memory controller for
