Subject: Merge tag 'firmware-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm... 
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e3d98847ded1d183111ff7c4d1ef56b161c7f13e;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Merge tag 'firmware-for-linus' of git://git./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
