      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.

      FWU: Add Generic Firmware Update framework support in BL1 · 48bfb88e
      Yatharth Kochar authored
      Firmware update(a.k.a FWU) feature is part of the TBB architecture.
      BL1 is responsible for carrying out the FWU process if platform
      specific code detects that it is needed.
      
      This patch adds support for FWU feature support in BL1 which is
      included by enabling `TRUSTED_BOARD_BOOT` compile time flag.
      
      This patch adds bl1_fwu.c which contains all the core operations
      of FWU, which are; SMC handler, image copy, authentication, execution
      and resumption. It also adds bl1.h introducing #defines for all
      BL1 SMCs.
      
      Following platform porting functions are introduced:
      
      int bl1_plat_mem_check(uintptr_t mem_base, unsigned int mem_size,
      unsigned int flags);
      	This function can be used to add platform specific memory checks
      	for the provided base/size for the given security state.
      	The weak definition will invoke `assert()` and return -ENOMEM.
      
      __dead2 void bl1_plat_fwu_done(void *cookie, void *reserved);
      	This function can be used to initiate platform specific procedure
      	to mark completion of the FWU process.
      	The weak definition waits forever calling `wfi()`.
      
      plat_bl1_common.c contains weak definitions for above functions.
      
      FWU process starts when platform detects it and return the image_id
      other than BL2_IMAGE_ID by using `bl1_plat_get_next_image_id()` in
      `bl1_main()`.
      
      NOTE: User MUST provide platform specific real definition for
      bl1_plat_mem_check() in order to use it for Firmware update.
