One other thing to note, and I'm not sure if it's related to bits that
U-Boot does or something else, but USB doesn't work in linux on the
8Gb model, does on all others inc the rpi-400, when booted on newer
firmware Oct 15th works, Dec 15th doesn't.

I did a bit more testing and I think it's unrelated as well, I'll try
and dig some more when I get a moment.
