- * 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, the flash addresses is
- * fe800000 and ff800000. That way, u-boot knows where the flash is
- * and the user can download u-boot code from promjet to fef00000, a
- * more intuitive location than fe700000.
- *
- * Note that, on switching the boot location, fef00000 becomes fff00000.
