Subject: [PATCH 0/3] Add SMP support for i.MX7D

i.MX7D has 2 Cortex-A7 ARM cores, and it has a different GPC design
than i.MX6, so this patch set adds a new GPCV2 driver for i.MX7D,
and also adds runtime check in SMP code to support both Cortex-A9
and Cortex-A7 ARM cores.

With this patch set, i.MX7D can boot up SMP kernel with 2 CPUs.

  ARM: dts: imx7: support SMP boot up
  ARM: imx: add gpcv2 support
  ARM: imx: add SMP support for i.MX7D
