2014-08-10LZMA: Add a version of ulzma which takes the input and output buffer sizes.Gabe Black
This new version is used to implement the version which doesn't take the input and output buffer sizes.

If the size the lzma header claims it needs is bigger than the space we have, print a message and continue rather than erroring out. Apparently the encoder is lazy sometimes and just puts a large value there regardless of what the actual size is. This was the original intention for this code, but an outdated version of the patch ended up being submitted.

2013-03-13libpayload: Don't do unaligned accesses during LZMA decompressionGabe Black
Use memcpy to access a uint32_t that's inherently unaligned due to the layout of the LZMA header format. Built and booted on Daisy and saw a data abort go away. Built and booted into developer mode on Link and verified that bitmaps were decompressed/displayed correctly.

2011-08-04libpayload: Add liblzma, libcbfsPatrick Georgi
Add cbfs core from coreboot into libpayload, and to support lzma decode, add coreboot's lzma code, too. Carl-Daniel agreed to relicense the lzmadecode wrapper as BSD-l, solving licensing problems.
