* In MPC8641HPCN, allocate 16MB flash spaces at fe000000 and ff000000.
* There is an 8MB flash. In effect, the addresses from fe000000 to fe7fffff
* map to fe800000 to ffffffff, and ff000000 to ff7fffff map to ffffffff.
* However, when u-boot comes up, the flash_init needs hard start addresses
* to build its info table. For user convenience, we have the flash addresses
* as fe800000 and ff800000. That way, when we do flash operations, u-boot
* knows where the flash is and the user can download u-boot code from promjet to
* fef00000 <- more intuitive than fe700000. Note that, on switching the boot
* location, fef00000 becomes fff00000.
