Hi6220 is one mobile solution of Hisilicon, this patchset contains
initial support for Hi6220 SoC and HiKey development board, which
supports octal ARM Cortex A53 cores. Initial support is minimal and
includes just the arch configuration, clock driver, device tree
configuration.

PSCI is enabled in device tree and there is no problem to boot all the
octal 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
