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."
