Subject: [PATCH 0/2] arm64: Support Hisilicon Hip05-D02 board

Hip05-D02 Development Board is based on Cortex-A57, this patchset
contains initial support for Hip05-D02 Soc and Board. Initial support
is minimal and includes just the arch configuration, device tree
configuration.

PSCI is enabled in device tree and there is no problem to boot all the
16 cores, and the CPU hotplug is also working now, you can download and
compile the latest firmware based on the following link to run this
patch set.

Here have a question:
In devcie tree binding file: Documentation/devicetree/bindings/arm/gic.txt,
it only considers for maximum 8 cpus. So will we need change the
binding file and also use GIC_CPU_MASK_SIMPLE(16) for 16 cores?

Ok,but I think should be "hisilicon,hip05","arm,armv8".

Looks like should updtate gic.txt and use the GIC_CPU_MASK_SIMPLE(16) for 16 cores.

If the CPU is a starndard ARM core (such like CA53, CA57, etc), you
need directly use the CPU type which has been defined in:
Documentation/devicetree/bindings/arm/cpus.txt. So here hip05 is the
naming code for SoC? or for the CPU customized by Hisilicon?
