Hi Marc,
Add:
Reviewed-by: Yun Wu <wuyun.wu@huawei•com>
Acked-by: Zhen Lei <thunder.leizhen@huawei•com>
for the first 4 patches, that is:
> ARM: GIC: move some bits of GICv2 to a library-type file
> arm64: initial support for GICv3
> arm64: GICv3 device tree binding documentation
> arm64: boot protocol documentation update for GICv3
Cheers,
Abel.
