From: Greg Ungerer <gerg@xxxxxxxxxxx> The ColdFire MBAR register that holds the mapping of the peripheral region on some ColdFire CPUs is configurable. It can be configured at some address different to that of the bootloader that loaded the kernel. So hard set the MBAR register mapping at kernel startup time.
