      ARM Platforms: Load HW_CONFIG in BL2 · cab0b5b0
      Soby Mathew authored
      
      
      The patch adds the necessary changes to load HW_CONFIG in BL2 for
      ARM Platforms :
      
      1. The load address of HW_CONFIG is specified via the `hw_config_addr`
      property in TB_FW_CONFIG is loaded by BL1. The `hw_config_max_size`
      property defines the maximum size to be expected for the HW_CONFIG.
      The `arm_dyn_cfg_helpers.c` and corresponding header implements
      utility functions to parse these DT properties defined.
      The `arm_dyn_cfg.c` implements wrappers to these helpers to enable
      them to be invoked from ARM platform layer.
      
      2. `HW_CONFIG` is added to the `bl2_mem_params_descs[]` array which is
      the list of images to be loaded by BL2.
      
      3. The `libfdt` sources are now included when BL2 is built
      
      4. A new helper `populate_next_bl_params_config()` is introduced in
      desc_image_load.c to populate the subsequent executable BL images
      with the `hw_config` and the corresponding `fw_config` if available.
      The `plat_get_next_bl_params()` API for ARM platforms is modified to
      invoke this new helper.
      
      5. The implementation of `bl2_early_platform_setup2()` is modified to
      consider `arg0` as well in addition to `arg1` passed from BL1.
      
      6. Bump up the BL2 size for Juno to accommodate the inclusion of libfdt.

      ARM Platorms: Load TB_FW_CONFIG in BL1 · c228956a
      Soby Mathew authored
      
      
      This patch modifies the bl1_platform_setup() API to load and authenticate
      TB_FW_CONFIG in BL1. The load address of the same is passed on to BL2 in
      `arg0` of entrypoint info. The fvp_io_storage.c and arm_io_storage.c also
      adds entries corresponding to TB_FW_CONFIG. A helper function
      `arm_load_tb_fw_config()` is added to load and authenticate TB_FW_CONFIG
      if present.

      ARM Platforms: Migrate to new BL handover interface · 0c306cc0
      Soby Mathew authored
      
      
      This patch migrates the ARM Standard platforms to the new BL
      handover interface. The arm_blx_early_platform_setup() functions
      are also modified to take in 4 arguments. The `ARM_BL31_PLAT_PARAM_VAL`
      value passed to BL31 from BL2 is now in arg3 in preparation of dynamic
      configuration arguments.

      bl2-el3: Add BL2 at EL3 support in FVP · 81528dbc
      Roberto Vargas authored
      
      
      This patch add supports for the new API added for BL2 at EL3 for
      FVP. We don't have a non-TF Boot ROM for FVP, but this option can be
      tested setting specific parameters in the model.
      
      The bl2 image is loaded directly in memory instead of being loaded
      by a non-TF Boot ROM and the reset address is changed:
      
      	--data cluster0.cpu0=bl2.bin@0x4001000
      	-C cluster0.cpu0.RVBAR=0x4001000
      
      These parameters mean that in the cold boot path the processor will
      jump to BL2 again. For this reason, BL2 is loaded in dram in this
      case, to avoid other images reclaiming BL2 memory.

      SPM: Move S-EL1/S-EL0 xlat tables to TZC DRAM · 45d640f0
      Antonio Nino Diaz authored
      
      
      A new platform define, `PLAT_SP_IMAGE_XLAT_SECTION_NAME`, has been
      introduced to select the section where the translation tables used by
      the S-EL1/S-EL0 are placed.
      
      This define has been used to move the translation tables to DRAM secured
      by TrustZone.
      
      Most of the extra needed space in BL31 when SPM is enabled is due to the
      large size of the translation tables. By moving them to this memory
      region we can save 44 KiB.
      
      A new argument has been added to REGISTER_XLAT_CONTEXT2() to specify the
      region where the translation tables have to be placed by the linker.

      ARM platforms: Fixup AArch32 builds · 5744e874
      Soby Mathew authored
      
      
      This patch fixes a couple of issues for AArch32 builds on ARM reference
      platforms :
      
      1. The arm_def.h previously defined the same BL32_BASE value for AArch64 and
         AArch32 build. Since BL31 is not present in AArch32 mode, this meant that
         the BL31 memory is empty when built for AArch32. Hence this patch allocates
         BL32 to the memory region occupied by BL31 for AArch32 builds.
      
         As a side-effect of this change, the ARM_TSP_RAM_LOCATION macro cannot
         be used to control the load address of BL32 in AArch32 mode which was
         never the intention of the macro anyway.
      
      2. A static assert is added to sp_min linker script to check that the progbits
         are within the bounds expected when overlaid with other images.
      
      3. Fix specifying `SPD` when building Juno for AArch32 mode. Due to the quirks
         involved when building Juno for AArch32 mode, the build option SPD needed to
         specifed. This patch corrects this and also updates the documentation in the
         user-guide.
      
      4. Exclude BL31 from the build and FIP when building Juno for AArch32 mode. As
         a result the previous assumption that BL31 must be always present is removed
         and the certificates for BL31 is only generated if `NEED_BL31` is defined.

      Replace magic numbers in linkerscripts by PAGE_SIZE · a2aedac2
      Antonio Nino Diaz authored
      
      
      When defining different sections in linker scripts it is needed to align
      them to multiples of the page size. In most linker scripts this is done
      by aligning to the hardcoded value 4096 instead of PAGE_SIZE.
      
      This may be confusing when taking a look at all the codebase, as 4096
      is used in some parts that aren't meant to be a multiple of the page
      size.

      Refactor Statistical Profiling Extensions implementation · 281a08cc

      Factor out SPE operations in a separate file.  Use the publish
      subscribe framework to drain the SPE buffers before entering secure
      world.  Additionally, enable SPE before entering normal world.
      
      A side effect of this change is that the profiling buffers are now
      only drained when a transition from normal world to secure world
      happens.  Previously they were drained also on return from secure
      world, which is unnecessary as SPE is not supported in S-EL1.

      ARM platforms: Make arm_validate_ns_entrypoint() common · 71e7a4e5
      Jeenu Viswambharan authored
      
      
      The function arm_validate_ns_entrypoint() validates a given non-secure
      physical address. This function however specifically returns PSCI error
      codes.
      
      Non-secure physical address validation is potentially useful across ARM
      platforms, even for non-PSCI use cases. Therefore make this function
      common by returning 0 for success or -1 otherwise.
      
      Having made the function common, make arm_validate_psci_entrypoint() a
      wrapper around arm_validate_ns_entrypoint() which only translates return
      value into PSCI error codes. This wrapper is now used where
      arm_validate_ns_entrypoint() was currently used for PSCI entry point
      validation.

      ARM platforms: Migrate to using interrupt properties · b2c363b1
      Jeenu Viswambharan authored
      
      
      An earlier patch added provision for the platform to provide secure
      interrupt properties. ARM platforms already has a list of interrupts
      that fall into different secure groups.
      
      This patch defines macros that enumerate interrupt properties in the
      same fashion, and points the driver driver data to a list of interrupt
      properties rather than list of secure interrupts on ARM platforms.  The
      deprecated interrupt list definitions are however retained to support
      legacy builds.
      
      Configuration applied to individual interrupts remain unchanged, so no
      runtime behaviour change expected.
      
      NOTE: Platforms that use the arm/common function
      plat_arm_gic_driver_init() must replace their PLAT_ARM_G1S_IRQS and
      PLAT_ARM_G0_IRQS macro definitions with PLAT_ARM_G1S_IRQ_PROPS and
      PLAT_ARM_G0_IRQ_PROPS macros respectively, using the provided
      INTR_PROP_DESC macro.

      created using platform supplied linker script and data marked with
      the attribute `arm_el3_tzc_dram` will be placed in this section.
      The FVP makefile now defines the `PLAT_EXTRA_LD_SCRIPT` variable to
      allow inclusion of the platform linker script by the top level BL31
      linker script.

      mem_protect: Add DRAM2 to the list of mem protected ranges · b09ba056
      Roberto Vargas authored
      
      
      On ARM platforms, the maximum size of the address space is limited
      to 32-bits as defined in arm_def.h. In order to access DRAM2, which
      is defined beyond the 32-bit address space, the maximum address space
      is increased to 36-bits in AArch64. It is possible to increase the
      virtual space for AArch32, but it is more difficult and not supported
      for now.
      
      NOTE - the actual maximum memory address space is platform dependent
      and is checked at run-time by querying the PARange field in the
      ID_AA64MMFR0_EL1 register.

      mem_protect: Add mem_protect support in Juno and FVP for DRAM1 · f145403c
      Roberto Vargas authored
      
      
      mem_protect needs some kind of non-volatile memory because it has
      to remember its state across reset and power down events.
      The most suitable electronic part for this feature is a NVRAM
      which should be only accesible from the secure world. Juno and
      FVP lack such hardware and for this reason the MEM_PROTECT
      functionality is implemented with Flash EEPROM memory on both
      boards, even though this memory is accesible from the non-secure
      world. This is done only to show a full implementation of
      these PSCI features, but an actual system shouldn't use a
      non-secure NVRAM to implement it.
      
      The EL3 runtime software will write the mem_protect flag and BL2
      will read and clear the memory ranges if enabled. It is done in
      BL2 because it reduces the time that TF needs access to the full
      non-secure memory.
      
      The memory layout of both boards is defined using macros which
      take different values in Juno and FVP platforms. Generic platform
      helpers are added that use the platform specific macros to generate
      a mem_region_t that is valid for the platform.

      plat/arm: Fix BL31_BASE when RESET_TO_BL31=1 · fd5763ea
      Qixiang Xu authored
      
      
      The value of BL31_BASE currently depends on the size of BL31. This
      causes problems in the RESET_TO_BL31 case because the value of
      BL31_BASE is used in the model launch parameters, which often changes.
      
      Therefore, this patch fixes BL31_BASE to the middle of Trusted SRAM,
      to avoid further model parameter changes in future.

      Fix JUNO AArch32 build · ba6c31da
      Soby Mathew authored
      
      
      This patch fixes the inconsistency with regards as to how
      BL2_BASE/BL2U_BASE and BL2_LIMIT/BL2U_LIMIT macros are defined
      when building Juno to run in AArch32 mode at EL3. In this case,
      BL32 is compiled for AArch32 whereas BL1 and BL2 are compiled
      for AArch64. This resulted in BL32 conditionally compiling a
      different definition of the above mentioned macros from BL1/BL2.
      This is fixed by taking into consideration the
      JUNO_AARCH32_EL3_RUNTIME build flag as well in the conditional
      compilation check.

      The correct interconnect to program is chosen at run time based on the
      FVP revision. Therefore, this patch implements FVP functions for
      interconnect programming, rather than depending on ARM generic ones. The
      macros used have been renamed to reflect this change.
      
      Additionally, this patch initializes SMMUv3 as part of FVP early
      platform setup.
      
      New ARM config flags are introduced for feature queries at run time.

      ARM plat changes to enable CryptoCell integration · e60f2af9
      Soby Mathew authored
      
      
      This patch makes the necessary changes to enable ARM platform to
      successfully integrate CryptoCell during Trusted Board Boot. The
      changes are as follows:
      
      * A new build option `ARM_CRYPTOCELL_INTEG` is introduced to select
        the CryptoCell crypto driver for Trusted Board boot.
      
      * The TrustZone filter settings for Non Secure DRAM is modified
        to allow CryptoCell to read this memory. This is required to
        authenticate BL33 which is loaded into the Non Secure DDR.
      
      * The CSS platforms are modified to use coherent stacks in BL1 and BL2
        when CryptoCell crypto is selected. This is because CryptoCell makes
        use of DMA to transfer data and the CryptoCell SBROM library allocates
        buffers on the stack during signature/hash verification.

      aarch64: Enable Statistical Profiling Extensions for lower ELs · d832aee9
      dp-arm authored
      
      
      SPE is only supported in non-secure state.  Accesses to SPE specific
      registers from SEL1 will trap to EL3.  During a world switch, before
      `TTBR` is modified the SPE profiling buffers are drained.  This is to
      avoid a potential invalid memory access in SEL1.
      
      SPE is architecturally specified only for AArch64.

      CSS: Add SCMI driver for SCP · c04a3b6c
      Soby Mathew authored
      
      
      This patch adds the SCMI driver for communicating with SCP. The power
      domain management and system power management protocol of the SCMI
      specification[1] is implemented in the driver. The SCP power management
      abstraction layer for SCMI for CSS power management is also added.
      
      A new buid option `CSS_USE_SCMI_DRIVER` is introduced to select SCMI
      driver over SCPI.

      Introduce ARM SiP service to switch execution state · b10d4499
      Jeenu Viswambharan authored
      
      
      In AArch64, privileged exception levels control the execution state
      (a.k.a. register width) of the immediate lower Exception Level; i.e.
      whether the lower exception level executes in AArch64 or AArch32 state.
      For an exception level to have its execution state changed at run time,
      it must request the change by raising a synchronous exception to the
      higher exception level.
      
      This patch implements and adds such a provision to the ARM SiP service,
      by which an immediate lower exception level can request to switch its
      execution state. The execution state is switched if the request is:
      
        - raised from non-secure world;
      
        - raised on the primary CPU, before any secondaries are brought online
          with CPU_ON PSCI call;
      
        - raised from an exception level immediately below EL3: EL2, if
          implemented; otherwise NS EL1.
      
      If successful, the SMC doesn't return to the caller, but to the entry
      point supplied with the call. Otherwise, the caller will observe the SMC
      returning with STATE_SW_E_DENIED code. If ARM Trusted Firmware is built
      for AArch32, the feature is not supported, and the call will always
      fail.
      
      For the ARM SiP service:
      
        - Add SMC function IDs for both AArch32 and AArch64;
        - Increment the SiP service minor version to 2;
        - Adjust the number of supported SiP service calls.
      
      Add documentation for ARM SiP service.

      Move defines in utils.h to utils_def.h to fix shared header compile issues · 53d9c9c8
      Scott Branden authored
      
      
      utils.h is included in various header files for the defines in it.
      Some of the other header files only contain defines.  This allows the
      header files to be shared between host and target builds for shared defines.
      
      Recently types.h has been included in utils.h as well as some function
      prototypes.
      
      Because of the inclusion of types.h conflicts exist building host tools
      abd these header files now.  To solve this problem,
      move the defines to utils_def.h and have this included by utils.h and
      change header files to only include utils_def.h and not pick up the new
      types.h being introduced.

      Changes to support execution in AArch32 state for JUNO · 07570d59
      Yatharth Kochar authored
      
      
      Following steps are required to boot JUNO in AArch32 state:
      1> BL1, in AArch64 state, loads BL2.
      2> BL2, in AArch64 state, initializes DDR.
        Loads SP_MIN & BL33 (AArch32 executable)images.
        Calls RUN_IMAGE SMC to go back to BL1.
      3> BL1 writes AArch32 executable opcodes, to load and branch
        at the entrypoint address of SP_MIN, at HI-VECTOR address and
        then request for warm reset in AArch32 state using RMR_EL3.
      
      This patch makes following changes to facilitate above steps:
      * Added assembly function to carry out step 3 above.
      * Added region in TZC that enables Secure access to the
        HI-VECTOR(0xFFFF0000) address space.
      * AArch32 image descriptor is used, in BL2, to load
        SP_MIN and BL33 AArch32 executable images.
      
      A new flag `JUNO_AARCH32_EL3_RUNTIME` is introduced that
      controls above changes. By default this flag is disabled.
      
      NOTE: BL1 and BL2 are not supported in AArch32 state for JUNO.

      ARM platforms: Add option to use xlat tables lib v1 · 3b211ff5
      Antonio Nino Diaz authored
      
      
      ARM platforms have migrated to the translation tables library v2.
      However, for testing purposes, it can be useful to temporarily switch
      back to the old version.
      
      This patch introduces the option `ARM_XLAT_TABLES_LIB_V1`, that switches
      to v1 of the library when is set to 1. By default, it is 0, so that ARM
      platforms use the new version unless specifically stated.
      
      Updated User Guide.

      Fix ARM_BL31_IN_DRAM build · f9608bc8
      Douglas Raillard authored
      
      
      Some header files using the ULL() macro were not directly including
      utils.h where the macro definition resides. As a consequence, a linker
      script with values using this macro did not see the macro definition
      and kept the "ULL(<value>)" call in the preprocessed file, which lead to
      link error.
      
      Files using ULL() macro now include utils.h directly.

      ARM platforms: Add support for MT bit in MPIDR · d8d6cf24
      Summer Qin authored
      
      
      This patch modifies some of the functions in ARM platform layer to cater
      for the case when multi-threading `MT` is set in MPIDR. A new build flag
      `ARM_PLAT_MT` is added, and when enabled, the functions accessing MPIDR
      now assume that the `MT` bit is set for the platform and access the bit
      fields accordingly.
      
      Also, a new API plat_arm_get_cpu_pe_count is added when `ARM_PLAT_MT` is
      enabled, returning the PE count within the physical cpu corresponding to
      `mpidr`.
