I do not see patch changing existing compatible. Which one is it?

I don't know what is your meaning of dependency then. For all of us,
dependency means one patch must be applied after another patch. So is
this the case here? If yes, then why?

If this is the question to me, then I am not the maintainer of your
platform. I am taking only memory controller bits, which look fine and I
would have already apply them if not the dependency trouble. Soon the
window for applying will close, BTW. We are almost at RC6.
