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,
