+			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.

+			==================
+
+  Introduction
+  ------------
+	The STM32F429 is a Cortex-M4 MCU aimed at various applications.
+	It features:
+	- ARM Cortex-M4 up to 180MHz with FPU
+	- 2MB internal Flash Memory
+	- External memory support through FMC controller (PSRAM, SDRAM, NOR, NAND)
+	- I2C, SPI, SAI, CAN, USB OTG, Ethernet controllers
+	- LCD controller & Camera interface
+	- Cryptographic processor
+
+  Resources
+  ---------
+	Datasheet and reference manual are publicly available on ST website:

 For the Vybrid SoC familiy all variants with DDR controller are supported,
 which is the VF5xx and VF6xx series. Out of historical reasons, in most
 places the kernel uses vf610 to refer to the whole familiy.
+The compatible string "fsl,vf610m4" is used for the secondary Cortex-M4
