      SPM: Treat SP xlat tables the same as others · d801a1d0
      Sandrine Bailleux authored
      The translation tables allocated for the Secure Partition do not need
      to be treated as a special case. They can be put amongst the other
      tables mapping BL31's general purpose memory. They will be mapped with
      the same attributes as them, which is fine.
      
      The explicit alignment constraint in BL31's linker script to pad the
      last page of memory allocated to the Secure Partition's translation
      tables is useless too, as page tables are per se pages, thus their
      end address is naturally aligned on a page-boundary.
      
      In fact, this patch does not change the existing behaviour. Since
      patch 22282bb6
      
       ("SPM: Move all SP-related info to SP context
      struct"), the secure_partition.c file has been renamed into sp_xlat.c
      but the linker script has not been properly updated. As a result, the
      SP translation tables are not specifically put at the start of the
      xlat_table linker section, the __SP_IMAGE_XLAT_TABLES_START__/_END__
      symbols have the same value, the size of the resulting mmap_region
      covering these xlat tables is 0 and so it is ignored.

      ARM platforms: Move BL31 below BL2 to enable BL2 overlay · c099cd39
      Soby Mathew authored
      
      
      The patch changes the layout of BL images in memory to enable
      more efficient use of available space. Previously BL31 was loaded
      with the expectation that BL2 memory would be reclaimed by BL32
      loaded in SRAM. But with increasing memory requirements in the
      firmware, we can no longer fit BL32 in SRAM anymore which means the
      BL2 memory is not reclaimed by any runtime image. Positioning BL2
      below BL1-RW and above BL31 means that the BL31 NOBITS can be
      overlaid on BL2 and BL1-RW.
      
      This patch also propogates the same memory layout to BL32 for AArch32
      mode. The reset addresses for the following configurations are also
      changed :
         * When RESET_TO_SP_MIN=1 for BL32 in AArch32 mode
         * When BL2_AT_EL3=1 for BL2
      
      The restriction on BL31 to be only in DRAM when SPM is enabled
      is now removed with this change. The update to the firmware design
      guide for the BL memory layout is done in the following patch.

      FVP: Add dummy configs for BL31, BL32 and BL33 · 1d71ba14
      Soby Mathew authored
      
      
      This patch adds soc_fw_config, tos_fw_config and nt_fw_config to the FVP.
      The config files are placeholders and do not have any useful bindings
      defined. The tos_fw_config is packaged in FIP and loaded by BL2 only
      if SPD=tspd. The load address of these configs are specified in tb_fw_config
      via new bindings defined for these configs. Currently, in FVP, the
      soc_fw_config and tos_fw_config is loaded in the page between BL2_BASE
      and ARM_SHARED_RAM. This memory was typically used for BL32 when
      ARM_TSP_RAM_LOCATION=tsram but since we cannot fit BL32 in that
      space anymore, it should be safe to use this memory for these configs.
      There is also a runtime check in arm_bl2_dyn_cfg_init() which ensures
      that this overlap doesn't happen.
      
      The previous arm_dyn_get_hwconfig_info() is modified to accept configs
      other than hw_config and hence renamed to arm_dyn_get_config_load_info().
      The patch also corrects the definition of ARM_TB_FW_CONFIG_LIMIT to be
      BL2_BASE.

      plat/arm: Fix incorrect number of reserved memory map entries · 3450fd62
      Chris Kay authored
      
      
      There are three calls to mmap_add_region() that always occur in
      arm_setup_page_tables(), and two further calls based on whether coherent
      memory is enabled, and whether SPM is enabled in BL31.
      
      This commit adapts the ARM_BL_REGIONS definition to match the number of
      calls made inside arm_setup_page_tables() so that the MAX_MMAP_REGIONS
      is realigned with what is actually occurring.

      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.

      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.

      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.

      ARM platforms: Add support for EL3 TZC memory region · a22dffc6
      Soby Mathew authored
      
      
      Some recent enhancements to EL3 runtime firmware like support for
      save and restoring GICv3 register context during system_suspend
      necessitates additional data memory for the firmware. This patch
      introduces support for creating a TZC secured DDR carveout for use
      by ARM reference platforms. A new linker section `el3_tzc_dram` is
      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.

      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.

      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.

      Resolve build errors flagged by GCC 6.2 · 9edac047
      David Cunado authored
      
      
      With GCC 6.2 compiler, more C undefined behaviour is being flagged as
      warnings, which result in build errors in ARM TF build.
      
      The specific issue that this patch resolves is the use of (1 << 31),
      which is predominantly used in case statements, where 1 is represented
      as a signed int. When shifted to msb the behaviour is undefined.
      
      The resolution is to specify 1 as an unsigned int using a convenience

      AArch32: Add essential ARM platform and FVP support · 877cf3ff
      Soby Mathew authored
      This patch adds AArch32 support for FVP and implements common platform APIs
      like `plat_get_my_stack`, `plat_set_my_stack`, `plat_my_core_cos` for AArch32.
      Only Multi Processor(MP) implementations of these functions are considered in
      this patch. The ARM Standard platform layer helpers are implemented for
      AArch32 and the common makefiles are modified to cater for both AArch64 and
      AArch32 builds. Compatibility with the deprecated platform API is not
      supported for AArch32.

      Remove BL32_BASE when building without SPD for FVP · 81d139d5
      Antonio Nino Diaz authored
      Previously, when building TF without SPD support, BL2 tried to load a
      BL32 image from the FIP and fails to find one, which resulted on
      warning messages on the console. Even if there is a BL32 image in the
      FIP it shouldn't be loaded because there is no way to transfer
      control to the Secure Payload without SPD support.
      
      The Makefile has been modified to pass a define of the form
      SPD_${SPD} to the source code the same way it's done for PLAT. The
      define SPD_none is then used to undefine BL32_BASE when BL32 is not
      used to prevent BL2 from trying to load a BL32 image and failing,
      thus removing the warning messages mentioned above.
      
      Fixes ARM-software/tf-issues#287

      Add support to load BL31 in DRAM · 4518dd9a
      David Wang authored
      This patch adds an option to the ARM common platforms to load BL31 in the
      TZC secured DRAM instead of the default secure SRAM.
      
      To enable this feature, set `ARM_BL31_IN_DRAM` to 1 in build options.
      If TSP is present, then setting this option also sets the TSP location
      to DRAM and ignores the `ARM_TSP_RAM_LOCATION` build flag.
      
      To use this feature, BL2 platform code must map in the DRAM used by
      BL31. The macro ARM_MAP_BL31_SEC_DRAM is provided for this purpose.
      Currently, only the FVP BL2 platform code maps in this DRAM.

      Fix the inconsistencies in bl1_tbbr_image_descs[] · 843ddee4
      Yatharth Kochar authored
      This patch fixes inconsistencies in bl1_tbbr_image_descs[]
      and miscellaneous fixes in Firmware Update code.
      
      Following are the changes:
      * As part of the original FWU changes, a `copied_size`
        field was added to `image_info_t`. This was a subtle binary
        compatibility break because it changed the size of the
        `bl31_params_t` struct, which could cause problems if
        somebody used different versions of BL2 or BL31, one with
        the old `image_info_t` and one with the new version.
        This patch put the `copied_size` within the `image_desc_t`.
      * EXECUTABLE flag is now stored in `ep_info.h.attr` in place
        of `image_info.h.attr`, associating it to an entrypoint.
      * The `image_info.image_base` is only relevant for secure
        images that are copied from non-secure memory into secure
        memory. This patch removes initializing `image_base` for
        non secure images in the bl1_tbbr_image_descs[].
      * A new macro `SET_STATIC_PARAM_HEAD` is added for populating
        bl1_tbbr_image_descs[].ep_info/image_info.h members statically.
        The version, image_type and image attributes are now
        populated using this new macro.
      * Added PLAT_ARM_NVM_BASE and PLAT_ARM_NVM_SIZE to avoid direct
        usage of V2M_FLASH0_XXX in plat/arm/common/arm_bl1_fwu.c.
      * Refactoring of code/macros related to SECURE and EXECUTABLE flags.
      
      NOTE: PLATFORM PORTS THAT RELY ON THE SIZE OF `image_info_t`
            OR USE the "EXECUTABLE" BIT WITHIN `image_info_t.h.attr`
            OR USE THEIR OWN `image_desc_t` ARRAY IN BL1, MAY BE
            BROKEN BY THIS CHANGE. THIS IS CONSIDERED UNLIKELY.

      Allow multi cluster topology definitions for ARM platforms · 0108047a
      Soby Mathew authored
      The common topology description helper funtions and macros for
      ARM Standard platforms assumed a dual cluster system. This is not
      flexible enough to scale to multi cluster platforms. This patch does
      the following changes for more flexibility in defining topology:
      
      1. The `plat_get_power_domain_tree_desc()` definition is moved from
         `arm_topology.c` to platform specific files, that is `fvp_topology.c`
         and `juno_topology.c`. Similarly the common definition of the porting
         macro `PLATFORM_CORE_COUNT` in `arm_def.h` is moved to platform
         specific `platform_def.h` header.
      
      2. The ARM common layer porting macros which were dual cluster specific
         are now removed and a new macro PLAT_ARM_CLUSTER_COUNT is introduced
         which must be defined by each ARM standard platform.
      
      3. A new mandatory ARM common layer porting API
         `plat_arm_get_cluster_core_count()` is introduced to enable the common
         implementation of `arm_check_mpidr()` to validate MPIDR.
      
      4. For the FVP platforms, a new build option `FVP_NUM_CLUSTERS` has been
         introduced which allows the user to specify the cluster count to be
         used to build the topology tree within Trusted Firmare. This enables
         Trusted Firmware to be built for multi cluster FVP models.

      ARM platforms: rationalise memory attributes of shared memory · 74eb26e4
      Juan Castillo authored
      The shared memory region on ARM platforms contains the mailboxes and,
      on Juno, the payload area for communication with the SCP. This shared
      memory may be configured as normal memory or device memory at build
      time by setting the platform flag 'PLAT_ARM_SHARED_RAM_CACHED' (on
      Juno, the value of this flag is defined by 'MHU_PAYLOAD_CACHED').
      When set as normal memory, the platform port performs the corresponding
      cache maintenance operations. From a functional point of view, this is
      the equivalent of setting the shared memory as device memory, so there
      is no need to maintain both options.
      
      This patch removes the option to specify the shared memory as normal
      memory on ARM platforms. Shared memory is always treated as device
      memory. Cache maintenance operations are no longer needed and have
      been replaced by data memory barriers to guarantee that payload and
      MHU are accessed in the right order.

      Re-factor definition of some macros on ARM platforms · ecf70f7b
      Vikram Kanigiri authored
      This patch moves the definition of some macros used only on
      ARM platforms from common headers to platform specific headers.
      It also forces all ARM standard platforms to have distinct
      definitions (even if they are usually the same).
       1. `PLAT_ARM_TZC_BASE` and `PLAT_ARM_NSTIMER_FRAME_ID` have been
           moved from `css_def.h` to `platform_def.h`.
       2. `MHU_BASE` used in CSS platforms is moved from common css_def.h
          to platform specific header `platform_def.h` on Juno and
          renamed as `PLAT_ARM_MHU_BASE`.
       3. To cater for different sizes of BL images, new macros like
          `PLAT_ARM_MAX_BL31_SIZE` have been created for each BL image. All
          ARM platforms need to define them for each image.
