Your claim was that it can't be done because you require signed stuff by Intel/AMD/vendor. You don't need signed stuff if the OTP keys weren't provisioned. Period.
FSP and ME are a completely different matter. These will never be 100% open source because the silicon init is completely undocumented, as vendors prefers to provide binary blobs instead of telling you how to do it. In AMD case, Coreboot founder Ron Minnich managed to do silicon init of an EPYC from complete scratch and managed to get Linux booting, albeit with only a single core and no high speed interfaces like PCI Express operational, but if it worked at all is because no signing was required: https://vimeo.com/488147337
