Hopefully this has received enough review to be merged (although a few more acks/review especially from DT people on patch 1 would be nice). Thanks everyone for all the input and comments! Trusted Foundations is an ARM secure monitor that is used by many Tegra-based retail devices (like SHIELD and TegraNote). 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 v7: - explicitly request the TF DT node to be under /firmware/ in the bindings documentation - renamed arguments of tf_generic_smc() (suggestion made by Linus W. some time ago that I overlooked). - fixed multi-line comment style TODO in a future patchset: - disable TF-dependant features (SMP, cpuidle) if TF cannot be supported instead or doing an early panic - complete TF support with idle and L2 cache handling (ongoing) Alexandre Courbot (5): ARM: add basic support for Trusted Foundations 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 .../arm/firmware/tl,trusted-foundations.txt | 20 ++++++ Documentation/devicetree/bindings/arm/tegra.txt | 5 ++ .../devicetree/bindings/vendor-prefixes.txt | 1 + arch/arm/Kconfig | 2 + arch/arm/Makefile | 1 + arch/arm/configs/tegra_defconfig | 1 + arch/arm/firmware/Kconfig | 28 ++++++++ arch/arm/firmware/Makefile | 1 + arch/arm/firmware/trusted_foundations.c | 79 ++++++++++++++++++++++ arch/arm/include/asm/trusted_foundations.h | 68 +++++++++++++++++++ arch/arm/mach-tegra/Kconfig | 1 + arch/arm/mach-tegra/common.c | 2 + arch/arm/mach-tegra/reset.c | 40 ++++++++--- 13 files changed, 238 insertions(+), 11 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/firmware/tl,trusted-foundations.txt create mode 100644 arch/arm/firmware/Kconfig create mode 100644 arch/arm/firmware/Makefile create mode 100644 arch/arm/firmware/trusted_foundations.c create mode 100644 arch/arm/include/asm/trusted_foundations.h -- 1.8.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
