ArmPkg/ArmGic: Implement GICv3+ version of GIC driver Most platforms do not require the flexibility of the ordinary GIC driver, which supports both GICv2 and GICv3+, and decides at runtime which version to use. So expose a GICv3+ version, which only supports a GICv3 or newer. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

ArmPkg/ArmGicDxe: Replace CpuArch registration event with DEPEX Instead of relying on a protocol notification event to register the core IRQ interrupt handler with CPU arch protocol once it becomes available, use a DEPEX to ensure that the GIC driver is not dispatched at all until the CPU arch protocol has turned up. This will allow the GIC driver to use other CPU arch protocol methods, such as the ones needed to map the GIC MMIO regions at driver startup. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
