Alexandre Courbot 5b154f1808 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.

Alexandre Courbot d9a1beaa10 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).
