Arnd, thanks very much for thinking. Now the codes are based on 2.6.38
and not quanified for sending patches. we will port them to be
againest linux's tree.
current diffstat for arch/arm againest 2.6.38 mainline is

i want to upstream steps by steps. send arch/arm patches for reviewing
at first, then clean-up drivers and send patches to subsystem for
reviewing. There are really too many issues waiting for refination in
arch/arm for the moment, we have more than 20 tasks for team to work.
