      Fix type of `unsigned long` constants · e47ac1fd
      Antonio Nino Diaz authored
      
      
      The type `unsigned long` is 32 bit wide in AArch32, but 64 bit wide in
      AArch64. This is inconsistent and that's why we avoid using it as per
      the Coding Guidelines. This patch changes all `UL` occurrences to `U`
      or `ULL` depending on the context so that the size of the constant is
      clear.
      
      This problem affected the macro `BIT(nr)`. As long as this macro is used
      to fill fields of registers, that's not a problem, since all registers
      are 32 bit wide in AArch32 and 64 bit wide in AArch64. However, if the
      macro is used to fill the fields of a 64-bit integer, it won't be able
      to set the upper 32 bits in AArch32.
      
      By changing the type of this macro to `unsigned long long` the behaviour
      is always the same regardless of the architecture, as this type is
      64-bit wide in both cases.
      
      Some Tegra platform files have been modified by this patch.

      Tegra: gic: fix MISRA defects · 9a8f05e4
      Varun Wadekar authored
      
      
      Main fixes:
      
      * Use int32_t replace int, use uint32_t replace unsign int [Rule 4.6]
      * Added explicit casts (e.g. 0U) to integers in order for them to be
        compatible with whatever operation they're used in [Rule 10.1]
      * Force operands of an operator to the same type category [Rule 10.4]
      * Fixed assert/if statements conditions to be essentially boolean [Rule 14.4]
      * Added curly braces ({}) around if statements in order to
        make them compound [Rule 15.6]
      * Convert macros form headers to unsigned ints

      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.

      Add missing features to the Tegra GIC driver · e1e094c7
      Varun Wadekar authored
      
      
      In order to handle secure/non-secure interrupts, overload the plat_ic_*
      functions and copy GIC helper functions from arm_gic.c. Use arm_gic.c
      as the reference to add Tegra's GIC helper functions.
      
      Now that Tegra has its own GIC implementation, we have no use for
      plat_gic.c and arm_gic.c files.

      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.

      Juno: Implement initial platform port · 01b916bf
      Sandrine Bailleux authored
      This patch adds the initial port of the ARM Trusted Firmware on the Juno
      development platform. This port does not support a BL3-2 image or any PSCI APIs
      apart from PSCI_VERSION and PSCI_CPU_ON. It enables workarounds for selected
      Cortex-A57 (#806969 & #813420) errata and implements the workaround for a Juno
      platform errata (Defect id 831273).

      Add support for selected Cortex-A57 errata workarounds · d9bdaf2d
      Soby Mathew authored
      This patch adds workarounds for selected errata which affect the Cortex-A57 r0p0
      part. Each workaround has a build time flag which should be used by the platform
      port to enable or disable the corresponding workaround. The workarounds are
      disabled by default. An assertion is raised if the platform enables a workaround
      which does not match the CPU revision at runtime.

      Add CPU specific power management operations · add40351
      Soby Mathew authored
      This patch adds CPU core and cluster power down sequences to the CPU specific
      operations framework introduced in a earlier patch. Cortex-A53, Cortex-A57 and
      generic AEM sequences have been added. The latter is suitable for the
      Foundation and Base AEM FVPs. A pointer to each CPU's operations structure is
      saved in the per-cpu data so that it can be easily accessed during power down
      seqeunces.
      
      An optional platform API has been introduced to allow a platform to disable the
      Accelerator Coherency Port (ACP) during a cluster power down sequence. The weak
      definition of this function (plat_disable_acp()) does not take any action. It
      should be overriden with a strong definition if the ACP is present on a
      platform.

      Clarify platform porting interface to TSP · 5a06bb7e
      Dan Handley authored
      * Move TSP platform porting functions to new file:
        include/bl32/tsp/platform_tsp.h.
      
      * Create new TSP_IRQ_SEC_PHY_TIMER definition for use by the generic
        TSP interrupt handling code, instead of depending on the FVP
        specific definition IRQ_SEC_PHY_TIMER.
      
      * Rename TSP platform porting functions from bl32_* to tsp_*, and
        definitions from BL32_* to TSP_*.
      
      * Update generic TSP code to use new platform porting function names
        and definitions.
      
      * Update FVP port accordingly and move all TSP source files to:
        plat/fvp/tsp/.
      
      * Update porting guide with above changes.
      
      Note: THIS CHANGE REQUIRES ALL PLATFORM PORTS OF THE TSP TO
            BE UPDATED

      Reduce deep nesting of header files · 97043ac9
      Dan Handley authored
      Reduce the number of header files included from other header
      files as much as possible without splitting the files. Use forward
      declarations where possible. This allows removal of some unnecessary
      "#ifndef __ASSEMBLY__" statements.
      
      Also, review the .c and .S files for which header files really need
      including and reorder the #include statements alphabetically.
