      Tegra: fixup GIC init from the 'on_finish' handler · 2a3dd384
      Varun Wadekar authored
      Commit e9e19fb2
      
       accidentally removed the
      GIC init routine required to initialze the distributor on system resume.
      
      This patch fixes this anomaly and initializes the distributor on system
      resume.

      Tegra194: move cluster and CPU counter to header file. · 9aaa8882
      Anthony Zhou authored
      
      
      MISRA rules request that the cluster and CPU counter be unsigned
      values and have a suffix 'U'. If the define located in the makefile,
      this cannot be done.
      
      This patch moves the PLATFORM_CLUSTER_COUNT and PLATFORM_MAX_CPUS_PER_CLUSTER
      macros to tegra_def.h as a result.

      Tegra210: trigger CPU0 hotplug power on using FC · a45c3e9d
      sumitg authored
      
      
      Hotplug poweron is not working for boot CPU as it's being
      triggerred using PMC and not with Flow Controller. This is
      happening because "cpu_powergate_mask" is only getting set
      for non-boot CPU's as the boot CPU's first bootup follows
      different code path. The patch is marking a CPU as ON within
      "cpu_powergate_mask" when turning its power domain on
      during power on. This will ensure only first bootup on all
      CPU's is using PMC and subsequent hotplug poweron will be
      using Flow Controller.

      Tegra: memctrl: cleanup streamid override registers · 36e26375
      Pritesh Raithatha authored
      
      
      Streamid override registers are passed to memctrl to program bypass
      streamid for all the registers. There is no reason to bypass SMMU
      for any of the client so need to remove register list and do not
      set streamid_override_cfg.
      
      Some Tegra186 platforms don't boot due to SDMMC failure so keep SDMMC
      bypass as of now. Will revisit once these issues are fixed.

      Tegra186: add SE support to generate SHA256 of TZRAM · 4eed9c84
      Jeetesh Burman authored
      
      
      The BL3-1 firmware code is stored in TZSRAM on Tegra186 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 SE SHA256 hash-result to PMC scratch registers.

      Tegra194: memctrl: remove support to reconfigure MSS · 4b74f6d2

      As bpmp-fw is running at the same time as ATF, and
      the mss client reconfiguration sequence involves performing
      a hot flush resets on bpmp, there is a chance that bpmp-fw is
      trying to perform accesses while the hot flush is active.
      
      Therefore, the mss client reconfigure has been moved to
      System Suspend resume fw and bootloader, and it can be
      removed from here.
