So all the peripherals are actually discoverable - awesome!

But the fact is that the only "vexpressness" of this tree is
memory@80000000 and gic@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?
