Hopefully final version of this patchset. If I'm not mistaken the last thing that prevents Stephen from merging it is Russel's Ack. Russel, could you check it? Trusted Foundations is an ARM secure monitor that is used by many Tegra-based retail devices (like SHIELD). Adding support to it allows these devices to boot on a purely upstream kernel. Public documentation about Trusted Foundations is scarce, but over the various versions of this patch it has been established that it does not follow the ARM SMC convention and also has no connection whatsoever with PSCI. As such, it requires an implementation of its own and the firmware interface introduced by Tomasz provides an adequate framework for it. Changes since v6: - Improved and simplified header conditionals when TF support is compiled in or not as advised by Stephen.
