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: - PLAT Supported Marvell platforms are: - a3700 - A3720 DB, EspressoBin and Turris MOX - a70x0 - a70x0_amc - AMC board - a80x0 - a80x0_mcbin - MacchiatoBin - a80x0_puzzle - IEI Puzzle-M801 - t9130 - CN913x - 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" - 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 512MB (DB-88F3720-DDR3-Modular, EspressoBin V3-V5) - 1 - DDR4 1CS 512MB (DB-88F3720-DDR4-Modular) - 2 - DDR3 2CS 1GB (EspressoBin V3-V5) - 3 - DDR4 2CS 4GB (DB-88F3720-DDR4-Modular) - 4 - DDR3 1CS 1GB (DB-88F3720-DDR3-Modular, EspressoBin V3-V5) - 5 - DDR4 1CS 1GB (EspressoBin V7, EspressoBin-Ultra) - 6 - DDR4 2CS 2GB (EspressoBin V7) - 7 - DDR3 2CS 2GB (EspressoBin V3-V5) - CUST - CUSTOMER BOARD (Customer board settings) - 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 Look at Armada37x0 chip package marking on board to identify correct CPU frequency. The last line on package marking (next line after the 88F37x0 line) should contain: - C080 or I080 - chip with 800 MHz CPU - use ``CLOCKSPRESET=CPU_800_DDR_800`` - C100 or I100 - chip with 1000 MHz CPU - use ``CLOCKSPRESET=CPU_1000_DDR_800`` - C120 - chip with 1200 MHz CPU - use ``CLOCKSPRESET=CPU_1200_DDR_750`` - 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 - 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 WTMI image can point to an image which does nothing, an image which supports EFUSE or a customized CM3 firmware binary. The default image is wtmi.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. - 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`` - CRYPTOPP_PATH For Armada37x0 only, use this parameter tp point to Crypto++ source code directory, which is required for building WTP image tool. 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= 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 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 Here is full example how to build production release of Marvell firmware image (concatenated binary of Marvell secure firmware, TF-A and U-Boot) for EspressoBin board (PLAT=a3700) with 1GHz CPU (CLOCKSPRESET=CPU_1000_DDR_800) and 1GB DDR4 RAM (DDR_TOPOLOGY=5): .. code:: shell > git clone https://review.trustedfirmware.org/TF-A/trusted-firmware-a > git clone https://gitlab.denx.de/u-boot/u-boot.git > git clone https://github.com/weidai11/cryptopp.git > git clone https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git -b master > git clone https://github.com/MarvellEmbeddedProcessors/A3700-utils-marvell.git -b master > make -C u-boot CROSS_COMPILE=aarch64-linux-gnu- mvebu_espressobin-88f3720_defconfig u-boot.bin > make -C trusted-firmware-a CROSS_COMPILE=aarch64-linux-gnu- CROSS_CM3=arm-linux-gnueabi- \ USE_COHERENT_MEM=0 PLAT=a3700 CLOCKSPRESET=CPU_1000_DDR_800 DDR_TOPOLOGY=5 \ MV_DDR_PATH=$PWD/mv-ddr-marvell/ WTP=$PWD/A3700-utils-marvell/ CRYPTOPP_PATH=$PWD/cryptopp/ \ BL33=$PWD/u-boot/u-boot.bin mrvl_flash Produced Marvell firmware flash image: ``trusted-firmware-a/build/a3700/release/flash-image.bin`` 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 (not available for Armada37x0) - 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 - Flashable Marvell firmware image. For Armada37x0 it contains TIM, WTMI and boot-image.bin images. For other platforms it contains BLe and boot-image.bin images. 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 and target ``mrvl_flash`` produce final ``flash-image.bin`` and ``uart-images.tgz.bin`` files. 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``.
