This sounds like an interesting idea, having a central repo for all
hardware information. A big problem I see is that while device-tree
syntax may make sense to Linux kernel propellerheads, to the average
Joe it's mind-numbing. Config files are ugly, but at least IMHO are
easy to figure out. User-friendly editing tools would be a necessity.
Maybe something already exists?

This should be fun considering the plethora of architectures that
U-boot supports.
