Subject: [PATCH 01/13] ARM: imx: add initial support for i.MXRT10xx family

From: Giulio Benetti <giulio.benetti@...ettiengineering.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.
