Sounds reasonable, I can make patches for other architectures, but I can
really only test ARM and x86

It's intended for systems that use USB keyboard as the primary input device.
I have a tegra2 device like that, I haven't sent out the patch to enable it yet
because it depends on Simon Glass's tegra USB patches, which are still in review.

Sure, that sounds reasonable.
