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?
