I've run NetBSD on an i.MX8MQ (an MNT Reform2 laptop), communicating
over its serial debug port.

Alas it doesn't boot normally since it seems like all the reset pins
that is expected to be on GPIO(?) aren't configured properly and that
causes the genfb to hang. Disabling genfb makes it boot all the way.
Additionally networking doesn't work either for (apparently) the same
GPIO reset pin reason.

This is probably a device tree problem but I don't know how to fix it
and I have found no useful information online (and nobody has been
inclined to tell me when I've asked either, yes I am a little bitter
about that).
