The big thing which concerns me is that we're using very generic
compatible strings here - has anyone done any searches to see whether
there are any existing standards for this kind of stuff already?

Even if none can be found, if we're going to create something like
this, it should probably become a public standard not just for Linux.

If we're not willing to do that, I'd suggest prefixing the compatible
strings with "linux," as a "company" identifier so that there's no
chance that we may hit some major problem caused by a conflicting
implementation in the future.

We could alternatively take the view that Linux will only ever be used
with Linux specific DT files, but I think that's a rather broken
approach given what DT is supposed to be.
