Hi everyone,
this patch adds the lzma support with the following constraints:
- it doesn't install the LZMA SDK files. I provide the import_lzma.sh
script to import the needs file from a lzma sdk release
- the imported lzma sdk files are _not touched_
- the lzma support is enabled defining the CONFIG_LZMA define
- I haven't tested this patch
- Use this patch at your own risk
The patch creates:
- the lib_lzma directory with the import_lzmasdk.sh script and a simple
front-end to LzmaDecode() fuction
- the include/lzma directory with some include files to use in the
U-Boot code
modifies:
- common/do_bootm.c file
- common/image.c file
- include/image.h file
Please read the lib_lzma/README.txt file.

Hi Luigi,
I have a stupid question in return: why do we want lzma (7zip) added to u-boot? The linux/uboot world is dominated by gzip. I realize 7zip has advantages over gzip albeit incremental, not revolutionary IIRC.
I am not aware of proposals or implementations of kernels compressed with lzma (could well be my ignorance). Adding more code for minimal benefits is a hard sell (we already have plenty of bloat :-O).
Best regards, gvb
Would be great if it's being used for squashfs-lzma support.
Thanks Donald
