Also, if these are KVM creations, shouldn't there be a "kvm" in the compatible string
somewhere?

There is nothing KVM specific about these platforms.  Any hypervisor
could create a similar virtual machine.

True, but I think we're on a slippery slope, here.  Virtualization allows us to
create "virtual platforms" that are not well defined.  Linux requires a unique
compatible string for each platform.

The device tree is supposed to describe the hardware (virtual or
otherwise), not just supply what Linux wants.  Perhaps there simply
shouldn't be a toplevel compatible if there's nothing appropriate to
describe there -- and fix whatever issues Linux has with that.

I guess my point is back to the name "corenet".  That just doesn't mean anything
to me, and I don't think it means much to anyone else, either.  That's why I
think that maybe "kvm" should be in the string, to at least indicate that it's a
virtualized environment.

But what about this is specific to kvm (the actual hypervisor info is
already described in /hypervisor)?  Then we'll have to add a platform match
for every other hypervisor out there that does the same thing.
