While many recent generations of past AMD CPU/APUs have worked with Coreboot, it's not clear going forward. One of AMD's key partners in supporting Coreboot, Sage Electronic Engineering, went out of business last year. It was a few months ago that Sage went bust, but it was quiet and I didn't even realize it until a Phoronix reader recently mentioned that fact.
Sage Electronic is now no more and was frequently cited by AMD as their contractor for Coreboot work. Sage's web-site is no longer active, but their final blog post about shutting down can be found here. Since Sage Electronic Engineering closed up shop, at least we've seen some commits by a few AMD engineers.
AMD Zen may cease support for Coreboot
