The series,

Tested-by: Stephen Warren <swarren@nvidia.com>

For reference, I tested on both Harmony (USB1+USB2 ULPI) and Seaboard
(really Springbank) (USB1+USB3). I applied these patches on top of
u-boot-usb/master, then merged in u-boot-tegra/next plus a few local
patches, and resolved the one minor conflict.

For the record so I can find it next time, the way to enable USB
keyboard for stdin on Springbank is: setenv stdin serial,usbkbd.

Thanks for rebasing!
