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"
