Re: [U-Boot] [PATCH 1/2] Add support for XZ decompression algorithm.

XZ (aka LZMA2) is the new version of lzma compression format. The following patch add a cut-down version of XZ Embedded library (v20100702) that supports only single-call API.

In order to enable XZ support, the CONFIG_XZ must be defined by board configuration file.

For any details, please refer to XZ Embedded homesite (http://tukaani.org/xz/embedded.html)

I really hope the text is misleading. Why use your own crc32 when u-boot has a pretty good one?
