Re: FYI: FreeBSD-14.0-CURRENT-arm-armv7-GENERICSD-20220930-42dc8696df5-258315.img is broken for RPi2 v1.1 (so: armv7)

[Summary: Both somewhat before and just after your ConOut commit
work. I'll have to do a rough bisect with the available armv7
artifacts that are after those but before October.]

Turns out that I had the time.

Use of the ./boot/loader.efi from a358db560370 substituted
into the failing main snapshot based microsd card worked
fine for both contexts:

A) Just serial console.
and:
B) Serial console and HDMI console at the same time.

I also tried the oldest artifact build with the loader change
in place:

https://artifact.ci.freebsd.org/snapshot/main/7ed3228323ef4f9e3130603ea68c3be9c2ed50ce/arm/armv7/
git: 7ed3228323ef - main - stand: Document that boot0 uses BIOS Warner Losh
Date/time: 2022-Aug-27 05:12

This also worked for both (A) and (B).

So it looks like I'll be doing a rough bisect to find a
before/after pair. It might have some elapsed time to
finish.
