Subject: * Patches by David Müller, 14 Nov 2003:   -
 board/mpl/common/common_util.c     * implement support for BZIP2 compressed
 images     * various cleanups (printf -> puts, ...)   -
 board/mpl/common/flash.c     * report correct errors to upper layers     *
 check the erase fail and VPP low bits in status reg   -
 board/mpl/vcma9/cmd_vcma9.c   - board/mpl/vcma9/flash.c     * various
 cleanups (printf -> puts, ...)   - common/cmd_usb.c     * fix typo in comment
   - cpu/arm920t/usb_ohci.c     * support for S3C2410 is missing in #if line  
 - drivers/cs8900.c     * reinit some registers in case of error (cable
 missing, ...)   - 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   -
 lib_arm/armlinux.c     * change calling convention of ARM Linux kernel as

* 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.)
