* Patches by Sean Chang, 09 Aug 2004:
- Added support for both 8 and 16 bit mode access to System ACE CF through MPU. - Fixed missing System ACE CF device during get FAT partition info in fat_register_device function. - Enabled System ACE CF support on ML300. * Patch by Sean Chang, 09 Aug 2004: Synch defines for saveenv and do_saveenv functions so they get compiled under the same statement.
