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

Pull ARM SoC platform updates from Arnd Bergmann:
 "This release brings up a new platform based on the old ARM9 core: the
  Nuvoton NPCM is used as a baseboard management controller, competing
  with the better known ASpeed AST2xx series.

  Another important change is the addition of ARMv7-A based chips in
  mach-stm32. The older parts in this platform are ARMv7-M based
  microcontrollers, now they are expanding to general-purpose workloads.

  The other changes are the usual defconfig updates to enable additional
  drivers, lesser bugfixes. The largest updates as often are the ongoing
  OMAP cleanups, but we also have a number of changes for the older PXA
  and davinci platforms this time.

  For the Renesas shmobile/r-car platform, some new infrastructure is
  needed to make the watchdog work correctly.

  Supporting Multiprocessing on Allwinner A80 required a significant
  amount of new code, but is not doing anything unexpected"

It is important to note that the Microchip (previously Atmel) ARM-based MPU

product line is historically named "AT91" or "at91" throughout the Linux kernel

development process even if this product prefix has completely disappeared from

the official Microchip product name. Anyway, files, directories, git trees,

git branches/tags and email subject always contain this "at91" sub-string.

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.
