Please also note the additional grub.cfg fix that we added:
### BEGIN /etc/grub.d/01_arm-efi-dt-fix ###
A secondary issue (for grub-efi-armhf) should also be created
regarding the detection of the grub module needed for /boot. That does
not seem to be happening and we have to explicitly do an insmod.
A tertiary issue (for grub-efi armhf and arm64) that we have
experienced and need feedback on is the support for part_msdos with
grub-install to support mbr partitioning schemes. A lot of armhf
systems use a boot sector that conflicts with GPT so the two
alternatives are to ship with a broken GPT table and let the system
use the backup table or support MBR. We currently address this with
adding "--modules=part_msdos" to grub-install and are fine continuing
to do so but it would warrant some consideration to just support it
out of the box.
