I will note that, for example, there is an UEFI/ACPI implementation
for the RPi4B (cortex-A72 so aarch64) and I can boot FreeBSD
with it (and sometimes do).

Similarly, the OverDrive 1000 and the MACCHIATObin Double Shot
have UEFI/ACPI but it is normal to boot that way with them.
There are probably other aarch64s as well (but I do not have
access to such).

Such points leaves me wondering about the #if logic above.
