+ 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.
