Actually I think a lot of A57 hardware right now is
using a standalone GIC. The ARM Server Base System
Architecture spec mandates a v2 GIC for level 0/1
compliance, GICv3 only comes in at level 2. So it's
not that far from reality (and it leaves us the
obvious space to put in a v3 GIC emulation eventually).

You first :-)
