I just tested current mainline U-Boot:

* 6aebc0d11a - (origin/master, origin/HEAD) Revert "fs: btrfs: fix false negatives in ROOT_ITEM 
search" (vor 2 Tagen) <Tom Rini>

on a not yet mainlined imx6ull port, and after SPL loaded U-Boot
into RAM I see no more output. After git bisect session, this
commit was found as the reason for breaking U-Boot.

After reverting this commit, board boots fine again...

Any Idea what could be wrong ?

Thanks!

bye,
Heiko
