It's worth noting that the M1 does not use EFI like Intel Macs do, so the kernel would still need to boot on this proprietary new mechanism. Apple previously indicated that the M1 Macs boot using a derivative of the iPhone/iPad boot procedure. There's a reasonable chance it'll still have something like the EFI buffer allocation mechanism, but it'll not be using a mainline standard. While it sucks that Apple ditched EFI, the good news is that it's probably reasonably well understood since Linux has already been booted on an iPhone 7 using Checkra1n [1] (and apparently with framebuffer support too!).
