It produces a working image. I have tested this with the other patch from https://reviews.freebsd.org/D43786

Assuming one can boot these with qemu-system-arm -m virt, great!
There may be one fix that's needed from stable that I don't think has made its way into 13.3 yet though. It's not fatal, but does make the virtionet work. Otherwise you have to specify real hardware to boot them. Which isn't terrible, but not completely ideal.

LGTM. Thanks for taking care of this!

Apologies for my silence on this review. I was a bit ... out when it was created, and did not see it until just today. I will try to get some comments in by the end of the week.

The size of this review has made it a little hard to review. Might make sense to make more, small reviews to help the turn-around time.

Ok from the docs@ side.

@emaste I just figured out man style. Is it alright to use the editor configs?

I've rephrased it a bit, to avoid multiple sentences which rendered as separate lines when built.
