Mixed results for starting with a modified
FreeBSD-13.0-RELEASE-arm-armv7-GENERICSD.img microsd
card:
orangepi-plus-2e booted from the microsd card.
rpi2 v1.1 failed the same way as before, including:
Found EFI removable media binary efi/boot/bootarm.efi

FYI, FreeBSD-13.0-RELEASE-arm64-aarch64-ROCK64.img includes
ubldr.bin :
