- fs/fat/fat.c
* support for USB/MMC devices is missing in #if line
- include/configs/MIP405.h
- include/configs/PIP405.h
* enable BZIP2 support
* enlarge malloc space to 1MiB because of BZIP2 support
- include/configs/VCMA9.h
* enable BZIP2 support
* enlarge malloc space to 1MiB because of BZIP2 support
* enable USB support

* Patch by Thomas Lange, 14 Nov 2003:
Split dbau1x00 into dbau1000, dbau1100 and dbau1500 configs to
support all these AMD boards.
* Patch by Thomas Lange, 14 Nov 2003:
Workaround for mips au1x00 physical memory accesses (the au1x00
uses a 36 bit bus internally and cannot access physical memory
directly. Use the uncached SDRAM address instead of the physical
one.)
