      Tegra: GIC: differentiate between FIQs targeted towards EL3/S-EL1 · 45eab456
      Varun Wadekar authored
      
      
      This patch modifies the secure IRQ registration process to allow platforms
      to specify the target CPUs as well as the owner of the IRQ. IRQs "owned"
      by the EL3 would return INTR_TYPE_EL3 whereas those owned by the Trusted
      OS would return INTR_TYPE_S_EL1 as a result.

      Tegra: GIC: enable FIQ interrupt handling · d3360301
      Varun Wadekar authored
      
      
      Tegra chips support multiple FIQ interrupt sources. These interrupts
      are enabled in the GICD/GICC interfaces by the tegra_gic driver. A
      new FIQ handler would be added in a subsequent change which can be
      registered by the platform code.
      
      This patch adds the GIC programming as part of the tegra_gic_setup()
      which now takes an array of all the FIQ interrupts to be enabled for
      the platform. The Tegra132 and Tegra210 platforms right now do not
      register for any FIQ interrupts themselves, but will definitely use
      this support in the future.

      Tegra: define platform power states · 9f9bafa3
      Varun Wadekar authored
      
      
      The platform power states, PLAT_MAX_RET_STATE and PLAT_MAX_OFF_STATE,
      can change on Tegra SoCs and so should be defined per-soc.
      
      This patch moves these macro definitions to individual SoC's tegra_def.h
      files.

      Tegra: drivers: memctrl: introduce function to secure on-chip TZRAM · 06b19d58
      Varun Wadekar authored
      
      
      This patch introduces a function to secure the on-chip TZRAM memory. The
      Tegra132 and Tegra210 chips do not have a compelling use case to lock the
      TZRAM. The trusted OS owns the TZRAM aperture on these chips and so it
      can take care of locking the aperture. This might not be true for future
      chips and this patch makes the TZRAM programming flexible.

      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: 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
