BTW, I tested tegra-kbc too, and that does indeed currently work (at least in my local dev branch based on u-boot/master).
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? :^)
Note that patch 2 has a merge conflict with the following patch in u-boot-tegra/next, since I assume your series is based on u-boot/master not u-boot-tegra/next:
799f182 ARM: tegra: use standard variables to define load addresses
It's pretty simple to resolve though.
Yes, I based it on u-boot/master, once we figure out what trees each patch is destined for I'll rebase appropriately.
