I'm doing some other experiments first but I'll
probably take a stab at it if things seem stable
enough. Pine64+ has multiple problems currently.
(It regressed some time back.)
Unfortunately I do not have a known way to reproduce
the older boot1.efi file fully. I'll have to explore
that part to have a known-good low bound. If I'm
lucky the first try from the general time frame will
happen to work.
Do to other issues I'm jumping from pre-INO64 to modern
without having tracked in the middle.
I will note that the older boot1.efi (as bootaa64.efi)
output is different (no "Load Path:"):
>> FreeBSD EFI boot block
Loader path: /boot/loader.efi
Initializing modules: ZFS UFS
Probing 3 block devices.....* done
ZFS found no pools
UFS found 1 partition
Consoles: EFI console
Command line arguments: loader.efi
Image base: 0xb6dbb008
EFI version: 2.05
EFI Firmware: Das U-boot (rev 0.00)
The failing one has garbage (invisible)
text after "Load Path:".
