Not that I know, perhaps the folks that do laptop FW upgrade have some
thoughts https://fwupd.org/ 

Actually maybe there's something in DMTF, does PLDM have standard image
format? Adding Jake. Not sure if PHYs would use it tho :S 

What's the interface that the PHY FW exposes? Ben H was of the opinion
that we should just expose the raw mtd devices.. just saying..
