Mike Frysinger f68ab43de6 lzma: ignore unset filesizes 
The Linux kernel build system changed how it compresses things with LZMA
such that the header no longer contains the filesize (it is instead set to
all F's).  So if we get a LZMA image that has -1 for the 64bit field,
let's just assume that the decompressed size is unknown and continue on.

README.txt 

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.
