I didn't test this patch yet, but from skimming over it it looks similar to what I tried with barebox a while back. What I did notice with the "set power" mbox call is that it takes way longer than 100ms (the current mbox call timeout) to finish on a cold boot. You don't seem to bump the timeout here, and with 100ms I always hit it and hence the mbox call failed for me. Don't you get these huge delays?
