I'm not sure re-porting is a great idea from the technical perspective.
I've been reading both drivers to compare them, there are also things in
U-Boot that're missing from coreboot. Things like DM integration are
also not there as they're U-Boot specific.

I checked some files with git log and checked the first commit that
showed up for each.
