Yes, 12.0 works fine. Also, after booted off an SD card, the image can be
dd-ed to the eMMC: perfectly works without SD card (except of spitting out
hundreds lot of meaningless messages:
Card did not respond to voltage select! )

I think, the difference with the previous images (11.x) is the fact that
u-boot is using EFI and it's a mainline u-boot, whilst the old images used
one specially tailored for FreeBSD.
