    Subject[PATCH v5 4/7] ARM: stm32: add initial support for STM32MP157
    Date
    From: Ludovic Barre <ludovic.barre@st.com>

    This patch adds initial support of STM32MP157 microprocessor (MPU)
    based on Arm Cortex-A7. New Cortex-A infrastructure (gic, timer,...)
    are selected if ARCH_MULTI_V7 is defined.

    +STM32MP157 Overview
    +===================
    +
    +Introduction
    +------------
    +
    +The STM32MP157 is a Cortex-A MPU aimed at various applications.
    +It features:
    +
    +- Dual core Cortex-A7 application core
    +- 2D/3D image composition with GPU
    +- Standard memories interface support
    +- Standard connectivity, widely inherited from the STM32 MCU family
    +- Comprehensive security support
