From 3ed71f8ad98a07803299693481b03fa6391e094f Mon Sep 17 00:00:00 2001 From: Ludovic Barre Date: Tue, 27 Feb 2018 09:05:18 +0100 Subject: ARM: stm32: prepare stm32 family to welcome armv7 architecture This patch prepares the STM32 machine for the integration of Cortex-A based microprocessor (MPU), on top of the existing Cortex-M microcontroller family (MCU). Since both MCUs and MPUs are sharing common hardware blocks we can keep using ARCH_STM32 flag for most of them. If a hardware block is specific to one family we can use either ARM_SINGLE_ARMV7M or ARCH_MULTI_V7 flag.
