How much work would have to be done to later get it working on x570 platforms? Is it just some quirk of X370 Killer SLI/ac that we can make a custom firmware for it and other platforms are automatically out of scope?

Crossflashing ASRock platforms with the same chipset is quite a popular practice so I guess at least porting the same work to other ASRock X370 mobos could be (relatively) easy unless there are some security features on other mobos 🤔

Just saw. x570 would require harder fiddling, I think, for now. only reason I got as far as I did with the x370 is the 'bios binary' (type 0x62 psp directory entry) was easy enough to modify to printf my platform descriptors and other stuff from the vendor bios to use in coreboot, and psb wasn't fused. newer bioses tend to use a compressed 0x62 entry which is a bit trickier to deal with, but hypothetically doable I guess.

However, I suppose that with better documentation than I had for the picasso/x570 work (wherein I had only what was available from independent researchers, the coreboot repository, and a boardview for the board in question) it may be more easily doable, assuming you intend to pair the x570 with a better cpu, as I rather doubt people would buy an x570 to slap a picasso apu in it (I didn't, lmao).
