+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 LzmaDecode.h, LzmaTypes.h, LzmaDecode.c, history.txt,
+ LGPL.txt, and lzma.txt from source archive into the lib_lzma directory (pwd).
+
+Example:
+
+ ./import_lzmasdk.sh ~/lzma457.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.
