There are no peripherals apart from the ones that are already described
here (timer, gic). All the peripherals that the guest sees are virtual
devices that show up on xenbus (a virtual bus). In order to initialize
xenbus, the guest only needs the hypervisor node.  So I'll remove the
ranges and interrupt-map.

So all the peripherals are actually discoverable - awesome!

But the fact is that the only "vexpressness" of this tree is
memory at 80000000 and gic at 2c001000. The rest (not much of it ;-) is a
"generic A15 platform". 

I understand that you had to use some "compatible" value to get
initialization code and I'm flattered ;-) by your choice of
"arm,vexpress", but maybe - as suggested by others - you would be better
off with generating this stuff in runtime, by whatever tool is used to
instantiate the guest?

Pawe?
