TF-A Build Instructions for Marvell Platforms
=============================================

This section describes how to compile the Trusted Firmware-A (TF-A) project for Marvell's platforms.

Build Instructions
------------------
(1) Set the cross compiler

    .. code:: shell

        > export CROSS_COMPILE=/path/to/toolchain/aarch64-linux-gnu-

(2) Set path for FIP images:

Set U-Boot image path (relatively to TF-A root or absolute path)

    .. code:: shell

        > export BL33=path/to/u-boot.bin

For example: if U-Boot project (and its images) is located at ``~/project/u-boot``,
BL33 should be ``~/project/u-boot/u-boot.bin``

    .. note::

       *u-boot.bin* should be used and not *u-boot-spl.bin*

Set MSS/SCP image path (mandatory only for A7K/8K/CN913x)

    .. code:: shell

        > export SCP_BL2=path/to/mrvl_scp_bl2*.img

(3) Armada-37x0 build requires WTP tools installation.

See below in the section "Tools and external components installation".
Install ARM 32-bit cross compiler, which is required for building WTMI image for CM3

    .. code:: shell

        > sudo apt-get install gcc-arm-linux-gnueabi

(4) Clean previous build residuals (if any)

    .. code:: shell

        > make distclean

(5) Build TF-A

There are several build options:

- DEBUG

        Default is without debug information (=0). in order to enable it use ``DEBUG=1``.
        Must be disabled when building UART recovery images due to current console driver
        implementation that is not compatible with Xmodem protocol used for boot image download.

- LOG_LEVEL

        Defines the level of logging which will be purged to the default output port.

            -  0 - LOG_LEVEL_NONE
            - 10 - LOG_LEVEL_ERROR
            - 20 - LOG_LEVEL_NOTICE (default for DEBUG=0)
            - 30 - LOG_LEVEL_WARNING
            - 40 - LOG_LEVEL_INFO (default for DEBUG=1)
            - 50 - LOG_LEVEL_VERBOSE

- USE_COHERENT_MEM

        This flag determines whether to include the coherent memory region in the
        BL memory map or not. Enabled by default.

- LLC_ENABLE

        Flag defining the LLC (L3) cache state. The cache is enabled by default (``LLC_ENABLE=1``).

- LLC_SRAM

        Flag enabling the LLC (L3) cache SRAM support. The LLC SRAM is activated and used
        by Trusted OS (OP-TEE OS, BL32). The TF-A only prepares CCU address translation windows
        for SRAM address range at BL31 execution stage with window target set to DRAM-0.
        When Trusted OS activates LLC SRAM, the CCU window target is changed to SRAM.
        There is no reason to enable this feature if OP-TEE OS built with CFG_WITH_PAGER=n.
        Only set LLC_SRAM=1 if OP-TEE OS is built with CFG_WITH_PAGER=y.

- CM3_SYSTEM_RESET

        For Armada37x0 only, when ``CM3_SYSTEM_RESET=1``, the Cortex-M3 secure coprocessor will
        be used for system reset.
        TF-A will send command 0x0009 with a magic value via the rWTM mailbox interface to the
        Cortex-M3 secure coprocessor.
        The firmware running in the coprocessor must either implement this functionality or
        ignore the 0x0009 command (which is true for the firmware from A3700-utils-marvell
        repository). If this option is enabled but the firmware does not support this command,
        an error message will be printed prior trying to reboot via the usual way.

        This option is needed on Turris MOX as a workaround to a HW bug which causes reset to
        sometime hang the board.

- MARVELL_SECURE_BOOT

        Build trusted(=1)/non trusted(=0) image, default is non trusted.

- BLE_PATH

        Points to BLE (Binary ROM extension) sources folder.
        Only required for A7K/8K/CN913x builds.
        The parameter is optional, its default value is ``plat/marvell/armada/a8k/common/ble``.

- MV_DDR_PATH

        For A7K/8K/CN913x, use this parameter to point to mv_ddr driver sources to allow BLE build. For A37x0,
        it is used for ddr_tool build.

        Usage example: MV_DDR_PATH=path/to/mv_ddr

        The parameter is optional for A7K/8K/CN913x, when this parameter is not set, the mv_ddr
        sources are expected to be located at: drivers/marvell/mv_ddr. However, the parameter
        is necessary for A37x0.

        For the mv_ddr source location, check the section "Tools and external components installation"

        If MV_DDR_PATH source code is a git snapshot then provide path to the full git
        repository (including .git subdir) because mv_ddr build process calls git commands.

- CP_NUM

        Total amount of CPs (South Bridge) connected to AP. When the parameter is omitted,
        the build uses the default number of CPs, which is a number of embedded CPs inside the
        package: 1 or 2 depending on the SoC used. The parameter is valid for OcteonTX2 CN913x SoC
        family (PLAT=t9130), which can have external CPs connected to the MCI ports. Valid
        values with CP_NUM are in a range of 1 to 3.

- DDR_TOPOLOGY

        For Armada37x0 only, the DDR topology map index/name, default is 0.

        Supported Options:
            -    0 - DDR3 1CS: DB-88F3720-DDR3-Modular (512MB); EspressoBIN (512MB)
            -    1 - DDR4 1CS: DB-88F3720-DDR4-Modular (512MB)
            -    2 - DDR3 2CS: EspressoBIN V3-V5 (1GB 2CS)
            -    3 - DDR4 2CS: DB-88F3720-DDR4-Modular (4GB)
            -    4 - DDR3 1CS: DB-88F3720-DDR3-Modular (1GB); EspressoBIN V3-V5 (1GB 1CS)
            -    5 - DDR4 1CS: EspressoBin V7 (1GB)
            -    6 - DDR4 2CS: EspressoBin V7 (2GB)
            -    7 - DDR3 2CS: EspressoBin V3-V5 (2GB)
            - CUST - CUSTOMER: Customer board, DDR3 1CS 512MB

- CLOCKSPRESET

        For Armada37x0 only, the clock tree configuration preset including CPU and DDR frequency,
        default is CPU_800_DDR_800.

            - CPU_600_DDR_600  - CPU at 600 MHz, DDR at 600 MHz
            - CPU_800_DDR_800  - CPU at 800 MHz, DDR at 800 MHz
            - CPU_1000_DDR_800 - CPU at 1000 MHz, DDR at 800 MHz
            - CPU_1200_DDR_750 - CPU at 1200 MHz, DDR at 750 MHz

- BOOTDEV

        For Armada37x0 only, the flash boot device, default is ``SPINOR``.

        Currently, Armada37x0 only supports ``SPINOR``, ``SPINAND``, ``EMMCNORM`` and ``SATA``:

            - SPINOR - SPI NOR flash boot
            - SPINAND - SPI NAND flash boot
            - EMMCNORM - eMMC Download Mode

                Download boot loader or program code from eMMC flash into CM3 or CA53
                Requires full initialization and command sequence

            - SATA - SATA device boot

                Image needs to be stored at disk LBA 0 or at disk partition with
                MBR type 0x4d (ASCII 'M' as in Marvell) or at disk partition with
                GPT name ``MARVELL BOOT PARTITION``.

- PARTNUM

        For Armada37x0 only, the boot partition number, default is 0.

        To boot from eMMC, the value should be aligned with the parameter in
        U-Boot with name of ``CONFIG_SYS_MMC_ENV_PART``, whose value by default is
        1. For details about CONFIG_SYS_MMC_ENV_PART, please refer to the U-Boot
        build instructions.

- WTMI_IMG

        For Armada37x0 only, the path of the binary can point to an image which
        does nothing, an image which supports EFUSE or a customized CM3 firmware
        binary. The default image is ``fuse.bin`` that built from sources in WTP
        folder, which is the next option. If the default image is OK, then this
        option should be skipped.

        Please note that this is not a full WTMI image, just a main loop without
        hardware initialization code. Final WTMI image is built from this WTMI_IMG
        binary and sys-init code from the WTP directory which sets DDR and CPU
        clocks according to DDR_TOPOLOGY and CLOCKSPRESET options.

- WTP

        For Armada37x0 only, use this parameter to point to wtptools source code
        directory, which can be found as a3700_utils.zip in the release. Usage
        example: ``WTP=/path/to/a3700_utils``

        If WTP source code is a git snapshot then provide path to the full git
        repository (including .git subdir) because WTP build process calls git commands.

- CRYPTOPP_PATH

        For Armada37x0 only, use this parameter to point to Crypto++ source code
        directory. If this option is specified then Crypto++ source code in
        CRYPTOPP_PATH directory will be automatically compiled. Crypto++ library
        is required for building WTP image tool. Either CRYPTOPP_PATH or
        CRYPTOPP_LIBDIR with CRYPTOPP_INCDIR needs to be specified for Armada37x0.

- CRYPTOPP_LIBDIR

        For Armada37x0 only, use this parameter to point to the directory with
        compiled Crypto++ library. By default it points to the CRYPTOPP_PATH.

- CRYPTOPP_INCDIR

        For Armada37x0 only, use this parameter to point to the directory with
        header files of Crypto++ library. By default it points to the CRYPTOPP_PATH.


For example, in order to build the image in debug mode with log level up to 'notice' level run

.. code:: shell

    > make DEBUG=1 USE_COHERENT_MEM=0 LOG_LEVEL=20 PLAT=<MARVELL_PLATFORM> mrvl_flash

And if we want to build a Armada37x0 image in debug mode with log level up to 'notice' level,
the image has the preset CPU at 1000 MHz, preset DDR3 at 800 MHz, the DDR topology of DDR4 2CS,
the image boot from SPI NOR flash partition 0, and the image is non trusted in WTP, the command
line is as following

.. code:: shell

    > make DEBUG=1 USE_COHERENT_MEM=0 LOG_LEVEL=20 CLOCKSPRESET=CPU_1000_DDR_800 \
        MARVELL_SECURE_BOOT=0 DDR_TOPOLOGY=3 BOOTDEV=SPINOR PARTNUM=0 PLAT=a3700 \
        MV_DDR_PATH=/path/to/mv-ddr-marvell/ WTP=/path/to/A3700-utils-marvell/ \
        CRYPTOPP_PATH=/path/to/cryptopp/ BL33=/path/to/u-boot.bin \
        all fip mrvl_bootimage mrvl_flash mrvl_uart

To build just TF-A without WTMI image (useful for A3720 Turris MOX board), run following command:

.. code:: shell

    > make USE_COHERENT_MEM=0 PLAT=a3700 CM3_SYSTEM_RESET=1 BL33=/path/to/u-boot.bin \
        CROSS_COMPILE=aarch64-linux-gnu- mrvl_bootimage

You can build TF-A for the Globalscale ESPRESSObin-Ultra board (DDR4, 1 GB) by running the following command:

.. code:: shell

    > make DEBUG=1 USE_COHERENT_MEM=0 LOG_LEVEL=20 CLOCKSPRESET=CPU_1200_DDR_750 \
        MARVELL_SECURE_BOOT=0 DDR_TOPOLOGY=5 BOOTDEV=SPINOR PARTNUM=0 PLAT=a3700 \
        MV_DDR_PATH=/path/to/mv-ddr-marvell/ WTP=/path/to/A3700-utils-marvell/ \
        CRYPTOPP_PATH=/path/to/cryptopp/ BL33=/path/to/u-boot.bin \
        all fip mrvl_bootimage mrvl_flash

Supported MARVELL_PLATFORM are:
    - a3700 (for both A3720 DB and EspressoBin)
    - a70x0
    - a70x0_amc (for AMC board)
    - a80x0
    - a80x0_mcbin (for MacchiatoBin)
    - a80x0_puzzle (for IEI Puzzle-M801)
    - t9130 (OcteonTX2 CN913x)

Special Build Flags
--------------------

- PLAT_RECOVERY_IMAGE_ENABLE
    When set this option to enable secondary recovery function when build atf.
    In order to build UART recovery image this operation should be disabled for
    A7K/8K/CN913x because of hardware limitation (boot from secondary image
    can interrupt UART recovery process). This MACRO definition is set in
    ``plat/marvell/armada/a8k/common/include/platform_def.h`` file.

- DDR32
    In order to work in 32bit DDR, instead of the default 64bit ECC DDR,
    this flag should be set to 1.

For more information about build options, please refer to the
:ref:`Build Options` document.


Build output
------------
Marvell's TF-A compilation generates 8 files:

    - ble.bin		- BLe image
    - bl1.bin		- BL1 image
    - bl2.bin		- BL2 image
    - bl31.bin		- BL31 image
    - fip.bin		- FIP image (contains BL2, BL31 & BL33 (U-Boot) images)
    - boot-image.bin	- TF-A image (contains BL1 and FIP images)
    - flash-image.bin	- Image which contains boot-image.bin and SPL image.
      Should be placed on the boot flash/device.
    - uart-images.tgz.bin - GZIPed TAR archive which contains Armada37x0 images
      for booting via UART. Could be loaded via Marvell's WtpDownload tool from
      A3700-utils-marvell repository.

Additional make target ``mrvl_bootimage`` produce ``boot-image.bin`` file. Target
``mrvl_flash`` produce final ``flash-image.bin`` file and target ``mrvl_uart``
produce ``uart-images.tgz.bin`` file.


Tools and external components installation
------------------------------------------

Armada37x0 Builds require installation of 3 components
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

(1) ARM cross compiler capable of building images for the service CPU (CM3).
    This component is usually included in the Linux host packages.
    On Debian/Ubuntu hosts the default GNU ARM tool chain can be installed
    using the following command

    .. code:: shell

        > sudo apt-get install gcc-arm-linux-gnueabi

    Only if required, the default tool chain prefix ``arm-linux-gnueabi-`` can be
    overwritten using the environment variable ``CROSS_CM3``.
    Example for BASH shell

    .. code:: shell

        > export CROSS_CM3=/opt/arm-cross/bin/arm-linux-gnueabi
