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.

STM32 ARM Linux Overview

========================
|
|
|
|
Introduction
|
|
------------
|
|
|
|
The STMicroelectronics STM32 family of Cortex-A microprocessors (MPUs) and
|
|
Cortex-M microcontrollers (MCUs) are supported by the 'STM32' platform of
|
|
ARM Linux.
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
For MCUs, use the provided default configuration:
|
|
make stm32_defconfig
|
|
For MPUs, use multi_v7 configuration:
|
|
make multi_v7_defconfig
|
|
|
|
Layout
|
|
------
|
|
|
|
All the files for multiple machine families are located in the platform code
|
|
contained in arch/arm/mach-stm32
|
|
|
|
There is a generic board board-dt.c in the mach folder which support
|
|
Flattened Device Tree, which means, it works with any compatible board with
|
|
Device Trees.
