      Tegra: lib: library for profiling the cold boot path · 087cf68a
      Varun Wadekar authored
      
      
      The non secure world would like to profile the boot path for
      the EL3 and S-EL1 firmwares. To allow it to do that, a non-secure
      DRAM region (4K) is allocated and the base address is passed to
      the EL3 firmware.
      
      This patch adds a library to allow the platform code to store the
      tag:timestamp pair to the shared memory. The tegra platform code
      then uses the `record` method to add timestamps.

      Tegra: init normal/crash console for platforms · e1084216
      Varun Wadekar authored
      
      
      The BL2 fills in the UART controller ID to be used as the normal as
      well as the crash console on Tegra platforms. The controller ID to
      UART controller base address mapping is handled by each Tegra SoC
      the base addresses might change across Tegra chips.
      
      This patch adds the handler to parse the platform params to get the
      UART ID for the per-soc handlers.

      Tegra: add tzdram_base to plat_params_from_bl2 struct · e0d4158c
      Varun Wadekar authored
      
      
      This patch adds another member, tzdram_base, to the plat_params_from_bl2 struct
      in order to store the TZDRAM carveout base address used to load the Trusted OS.
      The monitor programs the memory controller with the TZDRAM base and size in order
      to deny any accesses from the NS world.

      tlkd: delete 'NEED_BL32' build variable · 458c3c13
      Varun Wadekar authored
      
      
      Remove the 'NEED_BL32' flag from the makefile. TLK compiles using a
      completely different build system and is present on the device as a
      binary blob. The NEED_BL32 flag does not influence the TLK load/boot
      sequence at all. Moreover, it expects that TLK binary be present on
      the host before we can compile BL31 support for Tegra.
      
      This patch removes the flag from the makefile and thus decouples both
      the build systems.
      
      Tested by booting TLK without the NEED_BL32 flag.

      Tegra: Support for Tegra's T132 platforms · e7d4caa2
      Varun Wadekar authored
      
      
      This patch implements support for T132 (Denver CPU) based Tegra
      platforms.
      
      The following features have been added:
      
      * SiP calls to switch T132 CPU's AARCH mode
      * Complete PSCI support, including 'System Suspend'
      * Platform specific MMIO settings
      * Locking of CPU vector registers

      Boot Trusted OS' on Tegra SoCs · dc7fdad2
      Varun Wadekar authored
      
      
      This patch adds support to run a Trusted OS during boot time. The
      previous stage bootloader passes the entry point information in
      the 'bl32_ep_info' structure, which is passed over to the SPD.
      
      The build system expects the dispatcher to be passed as an input
      parameter using the 'SPD=<dispatcher>' option. The Tegra docs have
      also been updated with this information.

      Support for NVIDIA's Tegra T210 SoCs · 08438e24
      Varun Wadekar authored
      
      
      T210 is the latest chip in the Tegra family of SoCs from NVIDIA. It is an
      ARM v8 dual-cluster (A57/A53) SoC, with any one of the clusters being active
      at a given point in time.
      
      This patch adds support to boot the Trusted Firmware on T210 SoCs. The patch
      also adds support to boot secondary CPUs, enter/exit core power states for
      all CPUs in the slow/fast clusters. The support to switch between clusters
      is still not available in this patch and would be available later.
