I'd be fine with just getting a pull request with all the patches that
had no negative feedback and that were not already applied (if any).

Adding Sekhar and Kevin for DaVinci: At first sight, palm_bk3710 looks
fairly straightforward (meaning someone has to do a few day's work)
to convert into a libata driver.

As this is on on-chip controller that is part of a dm644x and dm646x,
it should also not be hard to test (as long as someone can find
a hard drive to plug in).
