Hi All,
I will rework the patch in order to include all files from LZMA SDK and some fix. I'll send the patch on Tuesday (I'm in vacation). These are the implemented features:
- LZMA SDK 4.57 Decode code (vanilla) - A Buff2Buff wrapper to decode the image (LZMA_Alone format) - Fixes for mkimage (option -C lzma) and do_bootm - small footprint and small impact on the u-boot sources.
To use the LZMA algorithm: just #define CONFIG_LZMA in your board config file.
Ciao.

But so far there is no code (board support) in U-Boot to use this feature, right? And it's not used by the Linux kernel either?
And your patch does not even enable support for it in the mkimage tool, so you cannot even create images that use the feature?
ive seen patches floating around to add lzma support akin to gzip/bzip2 in the uImage format. makes sense to me, and some people are very interested in shaving off flash space in return for slightly longer boot time. linux kernel is irrelevant here. someone else doing this means i dont have to at some point ;). -mike
