    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.

    Signed-off-by: Jesse Taube <Mr.Bossman075@gmail.com>
    [Jesse: removed SOC_IMXRT's 'depends on ARCH_MULTI_V7' and 'select
    ARM_GIC if ARCH_MULTI_V7']

    V1->V2:
    * Remove depends ARCH_MULTI_V7
    * Remove select PINCTRL_IMXRT
    * Change commit description
