Oh, and one other thing: unless I revert commit
c3c0331db1fb7b1f4ff41e144fc04353b37c785c, I do not get any output on the
debug uart, but I didn't want to send a revert commit without discussion,
even more so than the the other stuff I'm providing.

That being said, can anyone else with a rockchip device using u-boot
give current u-boot master a try and see if I'm the only one not getting
console output after that commit?
