Trees there are development stuff for 4.x MVL product (at least ppc-related), and now active development is heading for next release. I don't think you'll find these up-to-date sources in source.mvista.com, bit not because of internal reasons - almost all the efforts were brought up to the community and merged to the stock kernel tree. > So what is the difference between kernel.org and montavista's tree for > ML403. > > kernel.org is quite a bit ahead. > > Personally I'd recommend Denk's 2.6.19 tree (that's a 2.6.19 from > kernel.org with some ppc specific patches, afaik) and patching the EDK > 8.2 into it.

Sorry, but I guess "patching the EDK 8.2 into it" is not the thing maintainers are expecting to appear upstream. So, referred mvista code can be used as a reference, but a living solution requires careful consideration. Do some investigations, share the thoughts and you'll not be left alone. As a side note, most of the active work is in the mainstream kernel, MV, Denx and many others actively participating in it. -- Sincerely, Vitaly
