Excellent news, feel free to suggest any improvements that could be
done to improve the process.
Is there a page where I could contribute some information, or is this already written up?
In particular, I find that on a cold boot, it usually fails, because U-Boot is faster than
the disk can spin up. :-) However, if I then hit the reset button it boots fine. Others
might want to know that.
