Currently we unconditionally create a virtual GICv2 in the guest. Add a --irqchip= parameter to let the user specify a different GIC type for the guest, when omitting this parameter it still defaults to --irqchip=gicv2. For now the only other supported type is --irqchip=gicv3 Signed-off-by: Andre Przywara <andre.przywara@arm.com> [will: use pr_err instead of fprintf] Signed-off-by: Will Deacon <will.deacon@arm.com>
