This patch adds LZO decompression support to U-Boot. It is needed for the upcoming UBIFS support, since UBIFS uses LZO as default compressor/ decompressor. Since we only support read-only in UBIFS, only the decompressor is needed. All this is copied with minor changes from the current Linux kernel version (2.6.28-rc8). This patch only implements this LZO decompressor support for PPC. Other platforms using UBIFS will have to add the required "include/asm/unaligned.h" as well. It should be fairly easy to copy this from the Linux source tree as I have done it for PPC in this patch. Signed-off-by: Stefan Roese <sr@denx.de>
