Locally i had to revert 0a9e34056fcf86fb64e70bd281875eb7bbdbabde But i think we need to use the led labels from here: http://git.denx.de/?p=u-boot.git;a=commit;h=1480fdf8a6dad28de70ade72974db436f7967525 But i'm not 100% sure on how to access them, as gpio set led@2 returned: "Command 'gpio' failed: Error -22". for me too...
