Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 

Pull ARM SoC platform support updates from Kevin Hilman:
 "Our SoC branch usually contains expanded support for new SoCs and
  other core platform code.  Some highlights from this round:

   - sunxi: SMP support for A23 SoC
   - socpga: big-endian support
   - pxa: conversion to common clock framework
   - bcm: SMP support for BCM63138
   - imx: support new I.MX7D SoC
   - zte: basic support for ZX296702 SoC"

			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.

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

core support.
