Hi Jean Christophe,
thanks for your reply.
could you specify the size impact and performance impact? and on which board do you test it?
I tested u-boot over sh platforms and no size impact happens (just differencies of few bytes, you can verify this by yourself) About performances, really I obtain a 15% improvement during decompression. Moreover I have to say that, working for my company, we have improved more and more u-boot time just applying other patches regarding different area other than the zlib common one.
Please, let me know if my patch will be useful for the community. Best Regards, Giuseppe
