    Subject[PATCH v5 0/8] Support Trusted Foundations firmware on Tegra30
    Date
    Hello,

    This patchset adds support for the Trusted Foundations firmware on
    NVIDIA Tegra30. Pretty much all of Tegra30 consumer devices have that
    firmware and upstream kernel can't boot on those devices without the
    firmware support.

    Changelog:

    v5: - Fixed machine hanging on disabling D-cache during suspend,
    turned out there are slight variations in behaviour between
    firmware version in regards to cache-management. Thanks to
    Robert Yang for reporting the problem and helping with the
    solution.

    v4: - Fixed Thumb2-kernel hanging on Tegra20, turned out it was not a
    good idea to switch CPU into Thumb2 mode right after jumping into
    the reset handler.

    - Moved LP2-mode-set firmware call invocation to a later stage to
    better replicate what downstream kernel does. This change was
    suggested by Robert Yang and fixes system hang on Ouya game
    console.

    - Added references to the original work made by Michał Mirosław
    into commit messages of the relevant patches.

    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: Set up 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
