If it helps - try to not think of SBSA QEMU as a QEMU target.
It's pretending to be a hardware platform and should be treated as
such. While we may have started the firmware port from ArmVirtPkg (as
the qemu machine was being developed), I don't expect it to ultimately
end up there when it goes upstream.
