      Tegra: add 'late' platform setup handler · 3e1923d9
      Dilan Lee authored
      
      
      This patch adds a platform setup handler that gets called after
      the MMU is enabled. Platforms wanting to make use of this handler
      should declare 'plat_late_platform_setup' handler in their platform
      files, to override the default weakly defined handler.

      Tegra: spe: shared console for Tegra platforms · dd20f5b3
      Varun Wadekar authored
      
      
      There are Tegra platforms which have limited UART ports and so
      all the components have to share the console. The SPE helps out
      by collecting all the logs in such cases and prints them on the
      shared UART port.
      
      This patch adds a driver to communicate with the SPE driver, which
      in turn provides the console.

      makefiles and removes it from tegra_common.mk. This allows future
      platforms to include consoles of their choice.

      Tegra186: save system suspend entry marker to TZDRAM · 539c62d7
      Varun Wadekar authored
      
      
      This patch adds support to save the system suspend entry and exit
      markers to TZDRAM to help the trampoline code decide if the current
      warmboot is actually an exit from System Suspend.
      
      The Tegra186 platform handler sets the system suspend entry marker
      before entering SC7 state and the trampoline flips the state back to
      system resume, on exiting SC7.

      Tegra: rename secure scratch register macros · 601a8e54
      Steven Kao authored
      
      
      This patch renames all the secure scratch registers to reflect their
      usage.
      
      This is a list of all the macros being renamed:
      
      - SECURE_SCRATCH_RSV1_* -> SCRATCH_RESET_VECTOR_*
      - SECURE_SCRATCH_RSV6 -> SCRATCH_SECURE_BOOTP_FCFG
      - SECURE_SCRATCH_RSV11_* -> SCRATCH_SMMU_TABLE_ADDR_*
      - SECURE_SCRATCH_RSV53_* -> SCRATCH_BOOT_PARAMS_ADDR_*
      - SECURE_SCRATCH_RSV55_* -> SCRATCH_TZDRAM_ADDR_*
      
      NOTE: Future SoCs will have to define these macros to
            keep the drivers functioning.

      Tegra: bpmp_ipc: IPC driver to communicate with BPMP firmware · 26e2b93a
      Varun Wadekar authored
      
      
      This patch adds the driver to communicate with the BPMP firmware on Tegra
      SoCs, starting Tegra186. BPMP firmware is responsible for clock enable/
      disable requests, module resets among other things.
      
      MRQ is short for Message ReQuest. This is the general purpose, multi channel
      messaging protocol that is widely used to communicate with BPMP. This is further
      divided into a common high level protocol and a peer-specific low level protocol.
      The higher level protocol specifies the peer identification, channel definition
      and allocation, message structure, message semantics and message dispatch process
      whereas the lower level protocol defines actual message transfer implementation
      details. Currently, BPMP supports two lower level protocols - Token Mail Operations
      (TMO), IVC Mail Operations (IMO).
      
      This driver implements the IMO protocol. IMO is implemented using the IVC (Inter-VM
      Communication) protocol which is a lockless, shared memory messaging queue management
      protocol.
      
      The IVC peer is expected to perform the following as part of establishing a connection
      with BPMP.
      
      1. Initialize the channels with tegra_ivc_init() or its equivalent.
      2. Reset the channel with tegra_ivc_channel_reset. The peer should also ensure that
         BPMP is notified via the doorbell.
      3. Poll until the channel connection is established [tegra_ivc_channel_notified() return
         0]. Interrupt BPMP with doorbell each time after tegra_ivc_channel_notified() return
         non zero.
      
      The IPC driver currently supports reseting the GPCDMAand XUSB_PADCTL hardware blocks. In
      future, more hardware blocks would be supported.

      Force operands of an operator to the same type category [Rule 10.4]
      
      Fixed if statement conditional to be essentially boolean [Rule 14.4]
