      refactor(tegra132): deprecate platform · d4ad3da0
      Varun Wadekar authored
      
      
      The Tegra132 platforms have reached their end of life and are
      no longer used in the field. Internally and externally, all
      known programs have removed support for this legacy platform.
      
      This change removes this platform from the Tegra tree as a result.

      Tegra: smmu: add smmu_verify function · 21ec61a9
      Varun Wadekar authored
      
      
      The SMMU configuration can get corrupted or updated by
      external clients during boot without our knowledge.
      
      This patch introduces a "verify" function for the SMMU
      driver, to check that the boot configuration settings are
      intact.  Usually, this function should be called at the
      end of the boot cycle.
      
      This function only calls panic() on silicon platforms.

      Tegra: print GICC registers conditionally · 7cd336ab
      Varun Wadekar authored
      
      
      The GICC interface exists only on the interrupt controllers following
      the GICv2 specification.
      
      This patch prints the GICC register contents from the platform's macro,
      plat_crash_print_regs' only when TEGRA_GICC_BASE is defined. This
      allows platforms using future versions of the GIC specification to
      still use this macro.

      Tegra186: system resume from TZSRAM memory · 2139c9c8
      Varun Wadekar authored
      
      
      TZSRAM loses power during System suspend, so the entire contents
      are copied to TZDRAM before Sysem Suspend entry. The warmboot code
      verifies and restores the contents to TZSRAM during System Resume.
      
      This patch removes the code that sets up CPU vector to point to
      TZSRAM during System Resume as a result. The trampoline code can
      also be completely removed as a result.

      Tegra186: disable PROGRAMMABLE_RESET_ADDRESS · 8336c94d
      Varun Wadekar authored
      
      
      This patch disables the code to program reset vector for secondary
      CPUs to a different entry point, than cold boot. The cold boot entry
      point has the ability to differentiate between a cold boot and a warm
      boot, that is controlled by the PROGRAMMABLE_RESET_ADDRESS macro. By
      reusing the same entry point, we can lock the CPU reset vector during
      cold boot.

      Tegra: smmu: remove context save sequence · a391d494
      Pritesh Raithatha authored
      
      
      SMMU and MC registers are saved as part of the System Suspend sequence.
      The register list includes some NS world SMMU registers that need to be
      saved by NS world software instead. All that remains as a result are
      the MC registers.
      
      This patch moves code to MC file as a result and renames all the
      variables and defines to use the MC prefix instead of SMMU. The
      Tegra186 and Tegra194 platform ports are updated to provide the MC
      context register list to the parent driver. The memory required for
      context save is reduced due to removal of the SMMU registers.

      Tegra194: add SE support to generate SHA256 of TZRAM · 029dd14e
      Jeetesh Burman authored
      
      
      The BL3-1 firmware code is stored in TZSRAM on Tegra194 platforms. This
      memory loses power when we enter System Suspend and so its contents are
      stored to TZDRAM, before entry. This opens up an attack vector where the
      TZDRAM contents might be tampered with when we are in the System Suspend
      mode. To mitigate this attack the SE engine calculates the hash of entire
      TZSRAM and stores it in PMC scratch, before we copy data to TZDRAM. The
      WB0 code will validate the TZDRAM and match the hash with the one in PMC
      scratch.
      
      This patch adds driver for the SE engine, with APIs to calculate the hash
      and store to PMC scratch registers.
