* 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.
