Yes, I also tried on a seaboard with internal keyboard and it works,
although once the USB keyboard driver loads the internal keyboard
stops working. I haven't tracked down why, but it seems like a bug I
can live with for now as seaboards with internal keyboards are pretty
rare these days, and how many keyboards do you need in u-boot anyway?
:^)

Yes, I based it on u-boot/master, once we figure out what trees each
patch is destined for I'll rebase appropriately.
