I might be confused, but I thought microcode updates on consumer

I'm not sure if we'll see a late-load .bin for the consumer
processors. If anybody can confirm or deny, please speak up.
BLFS shows how to update the microcode in an initrd. That's really just
having the kernel do what the BIOS update would do.
Bruce, the AGESA comment is specific to AMD R5/R7 processors. They
obviously intend to provide the files for at least Epyc. Nothing has
surfaced yet for Ryzen or Threadripper outside of the BIOS updates.
