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

Pull ARM platform specific firmware interfaces from Olof Johansson:
 "Two platforms, bcm and exynos have their own firmware interfaces using
  the "secure monitor call", this adds support for those.

  We had originally planned to have a third set of patches in here,
  which would extend support for the existing generic "psci" call that
  is used on multiple platforms as well as Xen and KVM guests, but that
  ended up getting dropped because the patches were not ready in time."
