      plat/arm: Sanitise includes · bd9344f6
      Antonio Nino Diaz authored
      
      
      Use full include paths like it is done for common includes.
      
      This cleanup was started in commit d40e0e08283a ("Sanitise includes
      across codebase"), but it only cleaned common files and drivers. This
      patch does the same to Arm platforms.

      plat/arm: Save BL2 descriptors to reserved memory. · 5b8d50e4
      Sathees Balya authored
      
      
      On ARM platforms, the BL2 memory can be overlaid by BL31/BL32. The memory
      descriptors describing the list of executable images are created in BL2
      R/W memory, which could be possibly corrupted later on by BL31/BL32 due
      to overlay. This patch creates a reserved location in SRAM for these
      descriptors and are copied over by BL2 before handing over to next BL
      image.
      
      Also this patch increases the PLAT_ARM_MAX_BL2_SIZE for juno when TBBR
      is enabled.
      
      Fixes ARM-Software/tf-issues#626

      plat/arm: Fix header dependencies · 234bc7f8
      Antonio Nino Diaz authored
      
      
      From now on, platform_def.h must include any header with definitions that
      are platform-specific (like arm_def.h) and the included headers mustn't
      include back platform_def.h, and shouldn't be used by other files. Only
      platform_def.h should be included in other files. This will ensure that all
      needed definitions are present, rather than needing to include all the
      headers in all the definitions' headers just in case.
      
      This also prevents problems like cyclic dependencies.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored
      Enforce full include path for includes. Deprecate old paths.
      
      The following folders inside include/lib have been left unchanged:
      
      - include/lib/cpus/${ARCH}
      - include/lib/el3_runtime/${ARCH}
      
      The reason for this change is that having a global namespace for
      includes isn't a good idea. It defeats one of the advantages of having
      folders and it introduces problems that are sometimes subtle (because
      you may not know the header you are actually including if there are two
      of them).
      
      For example, this patch had to be created because two headers were
      called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
      to avoid collision."). More recently, this patch has had similar
      problems: 46f9b2c3 ("drivers: add tzc380 support").
      
      This problem was introduced in commit 4ecca339
      
       ("Move include and
      source files to logical locations"). At that time, there weren't too
      many headers so it wasn't a real issue. However, time has shown that
      this creates problems.
      
      Platforms that want to preserve the way they include headers may add the
      removed paths to PLAT_INCLUDES, but this is discouraged.

      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 platform changes for new version of image loading · a8aa7fec
      Yatharth Kochar authored
      This patch adds changes in ARM platform code to use new
      version of image loading.
      
      Following are the major changes:
        -Refactor the signatures for bl31_early_platform_setup()
         and arm_bl31_early_platform_setup() function to use
         `void *` instead of `bl31_params_t *`.
        -Introduce `plat_arm_bl2_handle_scp_bl2()` to handle
         loading of SCP_BL2 image from BL2.
        -Remove usage of reserve_mem() function from
         `arm_bl1_early_platform_setup()`
        -Extract BL32 & BL33 entrypoint info, from the link list
         passed by BL2, in `arm_bl31_early_platform_setup()`
        -Provides weak definitions for following platform functions:
           plat_get_bl_image_load_info
           plat_get_next_bl_params
           plat_flush_next_bl_params
           bl2_plat_handle_post_image_load
        -Instantiates a descriptor array for ARM platforms
         describing image and entrypoint information for
         `SCP_BL2`, `BL31`, `BL32` and `BL33` images.
      
      All the above changes are conditionally compiled using the
      `LOAD_IMAGE_V2` flag.

      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.
