This is mostly copy+pasted from the orange-pi 5 port, so a bunch of things still need to be finished/looked over. But I was able to boot a fedora image over ACPI, so it's close to being usable.

I would post a screenshot but this site says 'image dimensions are too big'. So here's a tweet: https://x.com/danielcdev/status/1889075801787716016
