The flash is accessed through firmware calls. Patch 1/2 adds the Linux interface to these calls. Patch 2/2 adds a mtd driver that uses these calls. Because there's two subsystems involved here, there are a couple of methods to merge this: 1) The powerpc folks take 1/2, and the mtd folks take 2/2, to be applied once 1/2 is available (Michael has created a topic branch for this in the past, which can make things a little easier), or 2) One of the maintainers takes both patches, once the other has acked their patch. I'd suggest that it goes through the powerpc tree in this case, as that will be less likely to conflict. Either way, I'm happy.
