In addition, bootarm passes information about where to find the root device to the kernel automatically, so you shouldn’t need to specify a root= option. GENERIC and GENERIC64 kernels are setup to automatically use fb when available, so console=fb is also no longer required.

Great news!
It tried / played with that on my bananapro with some limited success:

- I just managed to boot successfully a netbsd elf kernel via network
/ pxe. (How to disable / reorder pxe booting?)

- I was not able to bootarm.efi this kernel from its local ffs2 (!)
netbsd partition on the sdcrad. Is bootarm.efi limited to ffs1?

- In case of a connected sata disk: Is it possible to directly boot
from that via bootarm.efi (or specify explicitly a boot device)?

Once the kernel is found and loaded everything seems to run fine!
