Hello, All consumer-grade Tegra30 devices, like Nexus 7 tablet; Ouya console and others, use Trusted Foundations firmware that doesn't allow CPU to access secure registers directly from the Linux kernel, these accesses shall be done via the firmware calls. This patch-series adds a full-featured support of the Trusted Foundations firmware that opens the door for supporting of various Tegra30-based devices in the upstream Linux kernel. Changelog: v3: - Implemented suspend-resume support. - Reworked arm/firmware/trusted_foundations.c a tad. Now cache is getting properly initialized, cache enabling / disabling is supported. v2: - The "Don't apply CPU erratas in insecure mode" patch got some cleanup, in particular resolved the messiness in __tegra_cpu_reset_handler_data. - Added a comment to tf_cache_write_sec(), justifying the warning message. Dmitry Osipenko (8): ARM: trusted_foundations: Implement L2 cache initialization callback ARM: trusted_foundations: Make prepare_idle call to take mode argument ARM: trusted_foundations: Provide information about whether firmware is registered ARM: tegra: Setup L2 cache using Trusted Foundations firmware ARM: tegra: Don't apply CPU erratas in insecure mode ARM: tegra: Always boot CPU in ARM-mode ARM: tegra: Support L2 cache maintenance done via firmware ARM: tegra: Add firmware calls required for suspend-resume arch/arm/firmware/trusted_foundations.c | 80 +++++++++++++++++++++- arch/arm/include/asm/firmware.h | 2 +- arch/arm/include/asm/trusted_foundations.h | 13 ++++ arch/arm/mach-tegra/cpuidle-tegra114.c | 3 +- arch/arm/mach-tegra/pm.c | 43 ++++++++++++ arch/arm/mach-tegra/reset-handler.S | 66 ++++++++++++++---- arch/arm/mach-tegra/reset.c | 3 + arch/arm/mach-tegra/reset.h | 9 ++- arch/arm/mach-tegra/sleep-tegra20.S | 4 ++ arch/arm/mach-tegra/sleep.S | 4 ++ arch/arm/mach-tegra/tegra.c | 10 +++ 11 files changed, 216 insertions(+), 21 deletions(-)
