The lib_lzma functionality was written by Igor Pavlov. The original source cames from the LZMA SDK web page: URL: http://www.7-zip.org/sdk.html Author: Igor Pavlov The import is made using the import_lzmasdk.sh script that: * untars the lzmaXYY.tar.bz2 file (from the download web page) * copies the files LzmaDec.h, Types.h, LzmaDec.c, history.txt, and lzma.txt from source archive into the lib_lzma directory (pwd). Example: . import_lzmasdk.sh ~/lzma465.tar.bz2 Notice: The files from lzma sdk are _not modified_ by this script! The files LzmaTools.{c,h} are provided to export the lzmaBuffToBuffDecompress() function that wraps the complex LzmaDecode() function from the LZMA SDK. The do_bootm() function uses the lzmaBuffToBuffDecopress() function to expand the compressed image. The directory U-BOOT/include/lzma contains stubs files that permit to use the library directly from U-BOOT code without touching the original LZMA SDK's files. Luigi 'Comio' Mantellini
