* 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 described on http://www.arm.linux.org.uk/developer/booting.php * 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.)
