ARM: add basic support for Trusted Foundations Trusted Foundations is a TrustZone-based secure monitor for ARM that can be invoked using the same SMC-based API on supported platforms. This patch adds initial basic support for Trusted Foundations using the ARM firmware API. Current features are limited to the ability to boot secondary processors. Note: The API followed by Trusted Foundations does *not* follow the SMC calling conventions. It has nothing to do with PSCI neither and is only relevant to devices that use Trusted Foundations (like most Tegra-based retail devices).

ARM: firmware: enable Trusted Foundations by default As discussed previously (https://lkml.org/lkml/2013/11/26/289), enable Trusted Foundation support by default since it already depends on a supporting architecture being selected.

help
Some devices (including most Tegra-based consumer devices on the
market) are booted with the Trusted Foundations secure monitor
active, requiring some core operations to be performed by the secure
monitor instead of the kernel.
This option allows the kernel to invoke the secure monitor whenever
required on devices using Trusted Foundations. See
arch/arm/include/asm/trusted_foundations.h or the
ARM: trusted_foundations: fix vendor prefix typos of_register_trusted_foundations() and the firmware Kconfig used the wrong vendor prefix for Trusted Logic Mobility.
