BBB boot without of_upstream:
https://gist.github.com/jmenti/b8f7151e7666ca16b9bec7ec5b2efe17
BBB with of_upstream:
https://gist.github.com/jmenti/c22e017605d3d6c20189eaf3cfce6231

Seems like MMC enumeration is switched, BBB now boots to emergency shell.

Also forgot to mentioned that there are more failures on AM335 SK
than just MMC, related to USB and NAND I think.
