      FVP: Fix AArch32 dts for `interrupts` node · 5882c57c
      Soby Mathew authored
      The commit 8d2c4977
      
       changed the interrupt map in `rtsm_ve-motherboard.dtsi`
      for the Linux FDT sources to be compatible for FreeBSD. But this also
      introduced a regression for FVP AArch32 mode but was undetected till now
      because the corresponding DTB was not updated. This patch creates a
      new `rtsm_ve-motherboard-aarch32.dtsi` which reverts the change and is
      now included by the AArch32 DTS files.

      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.

      BL1: Deprecate the `bl1_init_bl2_mem_layout()` API · 101d01e2
      Soby Mathew authored
      
      
      The `bl1_init_bl2_mem_layout()` API is now deprecated. The default weak
      implementation of `bl1_plat_handle_post_image_load()` calculates the
      BL2 memory layout and populates the same in x1(r1). This ensures
      compatibility for the deprecated API.

      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.

      Introduce the new BL handover interface · a6f340fe
      Soby Mathew authored
      
      
      This patch introduces a new BL handover interface. It essentially allows
      passing 4 arguments between the different BL stages. Effort has been made
      so as to be compatible with the previous handover interface. The previous
      blx_early_platform_setup() platform API is now deprecated and the new
      blx_early_platform_setup2() variant is introduced. The weak compatiblity
      implementation for the new API is done in the `plat_bl_common.c` file.
      Some of the new arguments in the new API will be reserved for generic
      code use when dynamic configuration support is implemented. Otherwise
      the other registers are available for platform use.

      Dynamic cfg: Update the tools · e24659df
      Soby Mathew authored
      
      
      This patch updates the `fiptool` and `cert_create` for the
      `hw_config` and `tb_fw_config` dynamic configuration files.
      The necessary UUIDs and OIDs are assigned to these files and
      the `cert_create` is updated to generate appropriate hashes
      and include them in the "Trusted Boot FW Certificate". The
      `fiptool` is updated to allow the configs to be specified
      via cmdline and included in the generated FIP.

      Add image_id to bl1_plat_handle_post/pre_image_load() · 566034fc
      Soby Mathew authored
      
      
      This patch adds an argument to bl1_plat_post/pre_image_load() APIs
      to make it more future proof. The default implementation of
      these are moved to `plat_bl1_common.c` file.
      
      These APIs are now invoked appropriately in the FWU code path prior
      to or post image loading by BL1 and are not restricted
      to LOAD_IMAGE_V2.
      
      The patch also reorganizes some common platform files. The previous
      `plat_bl2_el3_common.c` and `platform_helpers_default.c` files are
      merged into a new `plat_bl_common.c` file.
      
      NOTE: The addition of an argument to the above mentioned platform APIs
      is not expected to have a great impact because these APIs were only
      recently added and are unlikely to be used.

      Redefine SMC_UNK as -1 instead of 0xFFFFFFFF · 4abd7fa7
      Antonio Nino Diaz authored
      
      
      According to the SMC Calling Convention (ARM DEN0028B):
      
          The Unknown SMC Function Identifier is a sign-extended value of
          (-1) that is returned in R0, W0 or X0 register.
      
      The value wasn't sign-extended because it was defined as a 32-bit
      unsigned value (0xFFFFFFFF).
      
      SMC_PREEMPT has been redefined as -2 for the same reason.
      
      NOTE: This might be a compatibility break for some AArch64 platforms
      that don't follow the previous version of the SMCCC (ARM DEN0028A)
      correctly. That document specifies that only the bottom 32 bits of the
      returned value must be checked. If a platform relies on the top 32 bits
      of the result being 0 (so that SMC_UNK is 0x00000000FFFFFFFF), it will
      have to fix its code to comply with the SMCCC.

      Remove URLs from comments · fb1198b1
      Antonio Nino Diaz authored
      
      
      This fixes all defects according to MISRA Rule 3.1: "The character
      sequences /* and // shall not be used within a comment". This affects
      all URLs in comments, so they have been removed:
      
      - The link in `sdei_state.c` can also be found in the documentation file
        `docs/sdei.rst`.
      
      - The bug that the file `io_fip.c` talks about doesn't affect the
        currently supported version of GCC, so it doesn't make sense to keep
        the comment. Note that the version of GCC officially supported is the
        one that comes with Linaro Release 17.10, which is GCC 6.2.
      
      - The link in `tzc400.c` was broken, and it didn't correctly direct to
        the Technical Reference Manual it should. The link has been replaced
        by the title of the document, which is more convenient when looking
        for the document.
