Subject: [PATCH v3 0/5] ARM: tegra: support for Trusted Foundations
Date: Tue, 13 Aug 2013 11:29:47 +0900 [thread overview]
Message-ID: <1376360992-1508-1-git-send-email-acourbot@nvidia.com> (raw)
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
