Looks like 2021.04 (even before 2021.04_1) also has the
problem for root-on-USB handling.

I managed to find a 2021-Apr-09 u-boot-orangepi-plus-2e
directory copy that was 2021.04 (and its boot.scr) but
before the UEFI change. When I tried it for the
root-on-USB context I still got the hangup after "Kernel
args: (null)" in:

. . .
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel]...               
Using DTB provided by EFI at 0x47eea000.
Kernel entry at 0xb2e00200...
Kernel args: (null)


So it does not appear to be the UEFI change so much as
2021.04 in general for which the FreeBSD kernel and
the U-Boot are apparently(?) mismatched for root-on-USB.


Reverting again to 2020.10 U-Boot got back the root-on-USB
status. For this the boot looks like:

. . .
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel]...               
Using DTB provided by EFI at 0x47ef5000.
Kernel entry at 0xb2e00200...
Kernel args: (null)
