Merge tag 'tegra-for-3.14-trusted-foundations' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/drivers
From Stephen Warren:
ARM: tegra: Trusted Foundations firmware support
Add support for the Trusted Foundations secure-mode firmware, as found
on NVIDIA SHIELD. This allows Linux to run in non-secure mode on this
board; all previous Tegra support has assumed the kernel is running in
secure mode.
(The base TF support has been discussed back and forth a lot; for now
the most logical place for it seems to be under arch/arm, so we're adding
it here. We can move it out to a common location in the future if needed).
* tag 'tegra-for-3.14-trusted-foundations' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
ARM: tegra: support Trusted Foundations by default
ARM: tegra: set CPU reset handler using firmware
ARM: tegra: split setting of CPU reset handler
ARM: tegra: add support for Trusted Foundations
of: add Trusted Foundations bindings documentation
of: add vendor prefix for Trusted Logic Mobility
ARM: add basic support for Trusted Foundations
