FreeBSD 12.1-BETA3 won't boot on Beaglebone Black

[Mike Karels]

Top-posting to avoid the search: has anyone looked at this?  Any thoughts
on where the problem might lie?  Any chance of getting it fixed for 12.1?

I could do something like a driver bisection, but a full bisection might
be a bit much on this platform.

Thanks,
		Mike
