From b1b4e89a0f3b75854c39a62cae41bad56d210adf Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 19 Mar 2009 15:34:56 +0100 Subject: Add LZO decompressor support 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.
