Many of these devices will run Linux though, and it's becomming increasingly more common as even the low end chips are pretty capable nowadays. It could be worthwhile to build some lightweight alternative to UEFI that just handles disk identification and handing off a devtree to whatever bootloader comes after it instead of implementing the behemoth of a spec that is all of UEFI. Call it "LWFI", "light-weight firmware interface"?

That just sounds like uboot.

Uboot does efi. It can also just exec Linux directly. But more interesting is whether the ram training code and ring -1 layers are open source.

Not really, no. Linux isn't going to run on a chip with 48k of memory which doesn't even have an MMU, and doing disk identification is pretty pointless when your "disk" is 256k on on-chip flash - or a hardsoldered 2M SPI chip if you are really lucky.
