2014-02-18ARM: firmware: enable Trusted Foundations by defaultAlexandre Courbot
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.

2013-12-13ARM: add basic support for Trusted FoundationsAlexandre Courbot
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).
