      Tegra: introduce plat_enable_console() · 117dbe6c
      Varun Wadekar authored
      
      
      This patch introduces the 'plat_enable_console' handler to allow
      the platform to enable the right console. Tegra194 platform supports
      multiple console, while all the previous platforms support only one
      console.
      
      For Tegra194 platforms, the previous bootloader checks the platform
      config and sets the uart-id boot parameter, to 0xFE. On seeing this
      boot parameter, the platform port uses the proper memory aperture
      base address to communicate with the SPE. This functionality is
      currently protected by a platform macro, ENABLE_CONSOLE_SPE.

      Tegra: fix defects flagged by MISRA Rule 10.3 · aa64c5fb
      Anthony Zhou authored
      
      
      MISRA Rule 10.3, the value of an expression shall not be assigned to
      an object with a narrower essential type or of a different essential
      type category.
      
      The essential type of a enum member is anonymous enum, the enum member
      should be casted to the right type when using it.
      
      Both UL and ULL suffix equal to uint64_t constant in compiler
      aarch64-linux-gnu-gcc, to avoid confusing, only keep U and ULL suffix
      in platform code. So in some case, cast a constant to uint32_t is
      necessary.

      Tegra186: reduce complexity for the 'get_target_pwr_state' handler · 4e1830a9
      Varun Wadekar authored
      
      
      This patch reduces the code complexity for the platform's 'get_target_pwr_state'
      handler, by reducing the number of 'if' conditions and adding helper functions
      to calculate power state for the cluster/system.
      
      Tested with 'pmccabe'

      Tegra: gpcdma: driver for general purpose DMA · 647d4a03
      Varun Wadekar authored
      
      
      This patch adds the driver for the general purpose DMA hardware
      block on newer Tegra SoCs. The GPCDMA is a special purpose DMA
      used to speed up memory copy operations to/from DRAM and TZSRAM.
      
      This patch introduces a macro 'USE_GPC_DMA' to allow platforms
      to override CPU based memory operations.
