      fiptool: fix add_image() and add_image_desc() implementation · 11c0a4ff
      Masahiro Yamada authored
      The "make fip" shows the content of the generated FIP at the end of
      the build.  (This is shown by "fiptool info" command.)
      
      Prior to commit e0f083a0 ("fiptool: Prepare ground for expanding
      the set of images at runtime"), the last part of the build log of
       make CROSS_COMPILE=aarch64-linux-gnu- BL33=../u-boot/u-boot.bin fip
      was like follows:
      
       Trusted Boot Firmware BL2: offset=0xB0, size=0x4188, cmdline="--tb-fw"
       EL3 Runtime Firmware BL31: offset=0x4238, size=0x6090, cmdline="--soc-fw"
       Non-Trusted Firmware BL33: offset=0xA2C8, size=0x58B51, cmdline="--nt-fw"
      
      With that commit, now it is displayed like follows:
      
       Non-Trusted Firmware BL33: offset=0xB0, size=0x58B51, cmdline="--nt-fw"
       EL3 Runtime Firmware BL31: offset=0x58C01, size=0x6090, cmdline="--soc-fw"
       Trusted Boot Firmware BL2: offset=0x5EC91, size=0x4188, cmdline="--tb-fw"
      
      You will notice two differences:
        - the contents are displayed in BL33, BL31, BL2 order
        - the offset values are wrong
      
      The latter is more serious, and means "fiptool info" is broken.
      
      Another interesting change is "fiptool update" every time reverses
      the image order.  For example, if you input FIP with BL2, BL31, BL33
      in this order, the command will pack BL33, BL31, BL2 into FIP, in
      this order.  Of course, the order of components is not a big deal
      except that users will have poor impression about this.
      
      The root cause is in the implementation of add_image(); the
      image_head points to the last added image.  For example, if you call
      add_image() for BL2, BL31, BL33 in this order, the resulted image
      chain is:
      
        image_head -> BL33 -> BL31 -> BL2
      
      Then, they are processed from the image_head in "for" loops:
      
        for (image = image_head; image != NULL; image = image->next) {
      
      This means images are handled in Last-In First-Out manner.
      
      Interestingly, "fiptool create" is still correct because
      add_image_desc() also reverses the descriptor order and the command
      works as before due to the double reverse.
      
      The implementation of add_image() is efficient, but it made the
      situation too complicated.
      
      Let's make image_head point to the first added image.  This will
      add_image() inefficient because every call of add_image() follows
      the ->next chain to get the tail.  We can solve it by adopting a
      nicer linked list structure, but I am not doing as far as that
      because we handle only limited number of images anyway.
      
      Do likewise for add_image_desc().
      
      Fixes: e0f083a0

      fiptool: introduce xzalloc() helper function · 696ccba6
      Masahiro Yamada authored
      
      
      We often want to zero out allocated memory.
      
      My main motivation for this commit is to set image::next and
      image_desc::next to NULL automatically in the next commit.

      fiptool: Link `toc_entry` and `image` structures via UUID · b04efcce
      dp-arm authored
      
      
      The `toc_entry` and `image` data structures had a cyclic
      relationship.  This patch removes the explicit dependencies and introduces
      functions to link them via the UUID.
      
      This change highlights the intent of the code better and makes it more
      flexible for future enhancements.

      fiptool: Invoke command specific usage function · 85ee2778
      dp-arm authored
      Instead of always calling the top level usage function when an
      error is detected, call the command-specific usage function.
      
      For example running `fiptool create` will produce the same output
      as `fiptool help create`.  This is more convenient for the user
      when they make a mistake.

      fiptool: Add support for printing the sha256 digest with info command · 9df69ba3
      dp-arm authored
      This feature allows one to quickly verify that the expected
      image is contained in the FIP without extracting the image and
      running sha256sum(1) on it.
      
      The sha256 digest is only shown when the verbose flag is used.
      
      This change requires libssl-dev to be installed in order to build
      Trusted Firmware. Previously, libssl-dev was optionally needed only
      to support Trusted Board Boot configurations.

      Replace fip_create with fiptool · 819281ee
      dp-arm authored
      fiptool provides a more consistent and intuitive interface compared to
      the fip_create program.  It serves as a better base to build on more
      features in the future.
      
      fiptool supports various subcommands.  Below are the currently
      supported subcommands:
      
      1) info   - List the images contained in a FIP file.
      2) create - Create a new FIP file with the given images.
      3) update - Update an existing FIP with the given images.
      4) unpack - Extract a selected set or all the images from a FIP file.
      5) remove - Remove images from a FIP file.  This is a new command that
         was not present in fip_create.
      
      To create a new FIP file, replace "fip_create" with "fiptool create".
      
      To update a FIP file, replace "fip_create" with "fiptool update".
      
      To dump the contents of a FIP file, replace "fip_create --dump" with
      "fiptool info".
      
      A compatibility script that emulates the basic functionality of
      fip_create is provided.  Existing scripts might or might not work with
      the compatibility script.  Users are strongly encouraged to migrate to
      fiptool.

      Fix `cert_create` tool for Segmentation fault · f16db56a
      Yatharth Kochar authored
      With the introduction of commit `96103d5a`, the Certificate
      Generation tool is not able to generate FWU certificate and
      while doing so it does segmentation fault.
      
      This happens because it is now required to pass non-volatile
      counter values to the `cert_create` tool from the command line
      for creating the trusted firmware certificates.
      
      But in case of creating FWU certificate these counter values are not
      being passed to the tool and as a consequence the `cert_create` tool
      try to use the NULL argument and errors out with Segmentation fault.
      
      This patch fixes this issue by providing a check before using the
      command line argument passed in the case of `EXT_TYPE_NVCOUNTER`
      certificate extension.

      fip_create: add support for image unpacking · c49a805d
      Juan Castillo authored
      This patch adds support for image unpacking to the FIP packaging
      tool. Command line option '-u,--unpack' may be used to unpack the
      contents of an existing FIP file into the working directory. The
      tool uses default hardcoded filenames for the unpacked images. If
      the files already exist, they can be overwritten by specifying the
      option '-f,--force'.

      Make:Allow for extension in tool names. · 42a45b51
      Evan Lloyd authored
      In some build environments executable programs have a specific file
      extension.  The value of BIN_EXT is appended to the relevant tool file
      names to allow for this.
      The value of BIN_EXT is set, where appropriate, by the build environment
      specific make helper (to .exe for Windows build environments).
      
      .gitignore is updated to hide the new (.exe) files.

      Build:Replace soft links with file copy. · bb5a762c
      Evan Lloyd authored
      Some build environments do not support symbolic links. This patch
      removes the symlinks previously used to build fip_create and instead
      copies the relevant header files.
      The original motivation for using symlinks was to avoid Trusted Firmware
      library headers conflicting with headers in the compiler standard
      include path. Copying the header files instead has the same effect.
      
      Like other build artefacts, the copied files are listed in .gitignore.
      
      The distclean targets have also been updated to remove the copies.

      Apply TBBR naming convention to the fip_create options · 8f0617ef
      Juan Castillo authored
      The fip_create tool specifies images in the command line using the
      ARM TF naming convention (--bl2, --bl31, etc), while the cert_create
      tool uses the TBBR convention (--tb-fw, --soc-fw, etc). This double
      convention is confusing and should be aligned.
      
      This patch updates the fip_create command line options to follow the
      TBBR naming convention. Usage examples in the User Guide have been
      also updated.
      
      NOTE: users that build the FIP by calling the fip_create tool directly
      from the command line must update the command line options in their
      scripts. Users that build the FIP by invoking the main ARM TF Makefile
      should not notice any difference.

      Always build with '-pedantic' · aa856917
      Sandrine Bailleux authored
      By default ARM TF is built with the '-pedantic' compiler flag, which
      helps detecting violations of the C standard. However, the mbed TLS
      library and its associated authentication module in TF used to fail
      building with this compiler flag. As a workaround, the mbed TLS
      authentication module makefile used to set the 'DISABLE_PEDANTIC'
      TF build flag.
      
      The compiler errors flagged by '-pedantic' in the mbed TLS library
      have been fixed between versions 1.3.9 and 2.2.0 and the library now
      properly builds with this compiler flag.
      
      This patch fixes the remaining compiler errors in the mbed TLS
      authentication module in TF and unsets the 'DISABLE_PEDANTIC' TF
      build flag. This means that TF is now always built with '-pedantic'.
      
      In particular, this patch:
      
       * Removes the final semi-colon in REGISTER_COT() macro.
      
         This semi-colon was causing the following error message:
      
         drivers/auth/tbbr/tbbr_cot.c:544:23: error: ISO C does not allow
         extra ';' outside of a function [-Werror=pedantic]
      
         This has been fixed both in the mbed TLS authentication module
         as well as in the certificate generation tool. Note that the latter
         code didn't need fixing since it is not built with '-pedantic' but
         the change has been propagated for consistency.
      
         Also fixed the REGISTER_KEYS() and REGISTER_EXTENSIONS() macros,
         which were suffering from the same issue.
      
       * Fixes a pointer type.
      
         It was causing the following error message:
      
         drivers/auth/mbedtls/mbedtls_crypto.c: In function 'verify_hash':
         drivers/auth/mbedtls/mbedtls_crypto.c:177:42: error: pointer of

      Replace all SCP FW (BL0, BL3-0) references · f59821d5
      Juan Castillo authored
      This patch replaces all references to the SCP Firmware (BL0, BL30,
      BL3-0, bl30) with the image terminology detailed in the TF wiki
      (https://github.com/ARM-software/arm-trusted-firmware/wiki):
      
          BL0          -->  SCP_BL1
          BL30, BL3-0  -->  SCP_BL2
          bl30         -->  scp_bl2
      
      This change affects code, documentation, build system, tools and
      platform ports that load SCP firmware. ARM plaforms have been
      updated to the new porting API.
      
      IMPORTANT: build option to specify the SCP FW image has changed:
      
          BL30 --> SCP_BL2
      
      IMPORTANT: This patch breaks compatibility for platforms that use BL2
      to load SCP firmware. Affected platforms must be updated as follows:
      
          BL30_IMAGE_ID --> SCP_BL2_IMAGE_ID
          BL30_BASE --> SCP_BL2_BASE
          bl2_plat_get_bl30_meminfo() --> bl2_plat_get_scp_bl2_meminfo()
          bl2_plat_handle_bl30() --> bl2_plat_handle_scp_bl2()

      TBB: apply TBBR naming convention to certificates and extensions · 516beb58
      Juan Castillo authored
      This patch applies the TBBR naming convention to the certificates
      and the corresponding extensions defined by the CoT:
      
          * Certificate UUID names
          * Certificate identifier names
          * OID names
      
      Changes apply to:
      
          * Generic code (variables and defines)
          * The default certificate identifiers provided in the generic
            code
          * Build system
          * ARM platforms port
          * cert_create tool internal definitions
          * fip_create and cert_create tools command line options
          * Documentation
      
      IMPORTANT: this change breaks the compatibility with platforms
      that use TBBR. The platform will need to adapt the identifiers
      and OIDs to the TBBR naming convention introduced by this patch:
      
      Certificate UUIDs:
      
          UUID_TRUSTED_BOOT_FIRMWARE_BL2_CERT --> UUID_TRUSTED_BOOT_FW_CERT
          UUID_SCP_FIRMWARE_BL30_KEY_CERT --> UUID_SCP_FW_KEY_CERT
          UUID_SCP_FIRMWARE_BL30_CERT --> UUID_SCP_FW_CONTENT_CERT
          UUID_EL3_RUNTIME_FIRMWARE_BL31_KEY_CERT --> UUID_SOC_FW_KEY_CERT
          UUID_EL3_RUNTIME_FIRMWARE_BL31_CERT --> UUID_SOC_FW_CONTENT_CERT
          UUID_SECURE_PAYLOAD_BL32_KEY_CERT --> UUID_TRUSTED_OS_FW_KEY_CERT
          UUID_SECURE_PAYLOAD_BL32_CERT --> UUID_TRUSTED_OS_FW_CONTENT_CERT
          UUID_NON_TRUSTED_FIRMWARE_BL33_KEY_CERT --> UUID_NON_TRUSTED_FW_KEY_CERT
          UUID_NON_TRUSTED_FIRMWARE_BL33_CERT --> UUID_NON_TRUSTED_FW_CONTENT_CERT
      
      Certificate identifiers:
      
          BL2_CERT_ID --> TRUSTED_BOOT_FW_CERT_ID
          BL30_KEY_CERT_ID --> SCP_FW_KEY_CERT_ID
          BL30_CERT_ID --> SCP_FW_CONTENT_CERT_ID
          BL31_KEY_CERT_ID --> SOC_FW_KEY_CERT_ID
          BL31_CERT_ID --> SOC_FW_CONTENT_CERT_ID
          BL32_KEY_CERT_ID --> TRUSTED_OS_FW_KEY_CERT_ID
          BL32_CERT_ID --> TRUSTED_OS_FW_CONTENT_CERT_ID
          BL33_KEY_CERT_ID --> NON_TRUSTED_FW_KEY_CERT_ID
          BL33_CERT_ID --> NON_TRUSTED_FW_CONTENT_CERT_ID
      
      OIDs:
      
          TZ_FW_NVCOUNTER_OID --> TRUSTED_FW_NVCOUNTER_OID
          NTZ_FW_NVCOUNTER_OID --> NON_TRUSTED_FW_NVCOUNTER_OID
          BL2_HASH_OID --> TRUSTED_BOOT_FW_HASH_OID
          TZ_WORLD_PK_OID --> TRUSTED_WORLD_PK_OID
          NTZ_WORLD_PK_OID --> NON_TRUSTED_WORLD_PK_OID
          BL30_CONTENT_CERT_PK_OID --> SCP_FW_CONTENT_CERT_PK_OID
          BL30_HASH_OID --> SCP_FW_HASH_OID
          BL31_CONTENT_CERT_PK_OID --> SOC_FW_CONTENT_CERT_PK_OID
          BL31_HASH_OID --> SOC_AP_FW_HASH_OID
          BL32_CONTENT_CERT_PK_OID --> TRUSTED_OS_FW_CONTENT_CERT_PK_OID
          BL32_HASH_OID --> TRUSTED_OS_FW_HASH_OID

      FWU: Add FWU support to `fip_create` tool · 2d4d2203
      Yatharth Kochar authored
      Firmware Update (FWU) introduces a new set of images called
      SCP_BL2U, BL2U and NS_BL2U, which can be packed in a FWU FIP file.
      
      This patch introduces new UUIDs for the Firmware Update images
      and extends the 'fip'create' tool so that these new images can be
      packed in a FIP file.

      FWU: Add FWU support to `cert_create` tool · cebe1f23
      Yatharth Kochar authored
      Firmware Update requires an X509v3 certificate which contains
      hashes for SCP_BL2U, BL2U and NS_BL2U images as extensions.
      
      This patch extends the Chain of Trust definition in the
      'cert_create' tool to include the Firmware Update certificate
      and the required extensions (including command line options).
      A new field in the extension structure will be used to indicate
      that the extension is optional. In the case of an image hash
      extension, this field will tell the tool that the hash should
      be included in the certificate, but filled with zeros.
