The real question here is how documented/open the boot loader is gonna be and if (how) it'll be possible to just boot whatever ARM64 code instead of going down the hypervisor way.
Yeah, I’m aware of that process. The question here is whether disabling secure boot (which in that video would allow running “even old macOS versions”) would also permit unsigned blobs to boot and set up the silicon.
We are still not sure about ASi’s memory map and if/how there are other limitations that might prevent it from booting anything other than macOS.
