* ARM: Use Linux version for unaligned access codeRemy Bohmer2009-11-07-0/+140
| | | | | | | | | | | | | | | | | | | | | The asm-arm/unaligned.h includes linux/unaligned/access_ok.h This file is unsafe to be used on ARM, since it does an unaligned memory accesses which fails on ARM. Lookin at Linux the basic difference seems to be the header "include/asm-arm/unaligned.h". The Linux version of "unaligned.h" does *not* include "access_ok.h" at all. It includes "le_byteshift.h" and "be_byteshift.h" instead.

* Add LZO decompressor supportStefan Roese2009-03-20-0/+137
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>
