I use rootfs from /dev/sda1 ,  spl and u-boot are on MicroSD card.
in armbianEnv.txt set rootdev=/dev/sda1 

Begin: Will now check root file system ... fsck from util-linux 2.27.1
[/sbin/fsck.ext4 (1) -- /dev/sda1] fsck.ext4 -a -C0 /dev/sda1

Are you suggesting ehci1 & ohci1 are not necessary in the u-boot DT file,
The kernel will initialize it after u-boot?
