Subject[PATCH v4 01/13] ARM: imx: add initial support for i.MXRT10xx family
Date
From: Giulio Benetti <giulio.benetti@benettiengineering.com>

The i.MXRT10xx family of processors features NXP's implementation of the
Arm Cortex-M7 core and in some case the Arm Cortex-M4 core too.

This patch aims to add an initial support for imxrt.

ARM_GIC if ARCH_MULTI_V7']
