 * In MPC8641HPCN, we allocate 16MB flash spaces at fe000000 and ff000000
 * We only have 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.
