Subject: [PATCH v3 0/5] ARM: tegra: support for Trusted Foundations

This is the long-overdue third version of this series, hopefully addressing the 
suggestions received in v2.

Since I could confirm that the SMC interface used by Trusted Foundations is not 
Tegra-specific, I have moved core TF support into arch/arm/firmware as a 
proposal to consolidate all implementations of Tomasz Figa's firmware interface 
into that directory.

Changes from v2:
- Moved core TF support into arch/arm/firmware
- Added TF version number in DT bindings
- Cleaned TF registration code
- Tegra kernel now fails if TF is declared in the device tree but support
  is not compiled in
- Tegra kernel now fails if attempt to set CPU reset vector through secure
  monitor returned an error
- Moved update to tegra_defconfig into its own patch

Alexandre Courbot (5):
  ARM: add basic Trusted Foundations support
  ARM: tegra: add support for Trusted Foundations
  ARM: tegra: split setting of CPU reset handler
  ARM: tegra: set CPU reset handler with firmware op
  ARM: tegra: support Trusted Foundations by default
