			STM32 ARM Linux Overview

			========================



Introduction

------------



  The STMicroelectronics family of Cortex-M based MCUs are supported by the

  'STM32' platform of ARM Linux. Currently only the STM32F429 is supported.





Configuration

-------------



  A generic configuration is provided for STM32 family, and can be used as the

  default by

	make stm32_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.
