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." * tag 'firmware-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: bcm: mark bcm_kona_smc_init as __init ARM: bcm281xx: Add DT support for SMC handler ARM: bcm281xx: Add L2 cache enable code ARM: EXYNOS: Add secure firmware support to secondary CPU bring-up ARM: EXYNOS: Add IO mapping for non-secure SYSRAM. ARM: EXYNOS: Add support for Exynos secure firmware ARM: EXYNOS: Add support for secure monitor calls ARM: Add interface for registering and calling firmware-specific operations
