| 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 Armada80x0) |
| |
| .. 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. |
| |
| LOG_LEVEL_NONE 0 |
| LOG_LEVEL_ERROR 10 |
| LOG_LEVEL_NOTICE 20 |
| LOG_LEVEL_WARNING 30 |
| LOG_LEVEL_INFO 40 |
| LOG_LEVEL_VERBOSE 50 |
| |
| - USE_COHERENT_MEM |
| |
| This flag determines whether to include the coherent memory region in the |
| BL memory map or not. |
| |
| - 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. |
| |
| - 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 A8K builds. |
| The parameter is optional, its default value is ``plat/marvell/armada/a8k/common/ble``. |
| |
| - MV_DDR_PATH |
| |
| For A7/8K, 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 A7/8K, 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" |
| |
| - DDR_TOPOLOGY |
| |
| For Armada37x0 only, the DDR topology map index/name, default is 0. |
| |
| Supported Options: |
| - DDR3 1CS (0): DB-88F3720-DDR3-Modular (512MB); EspressoBIN (512MB) |
| - DDR4 1CS (1): DB-88F3720-DDR4-Modular (512MB) |
| - DDR3 2CS (2): EspressoBIN V3-V5 (1GB) |
| - DDR4 2CS (3): DB-88F3720-DDR4-Modular (4GB) |
| - DDR3 1CS (4): DB-88F3720-DDR3-Modular (1GB) |
| - DDR4 1CS (5): EspressoBin V7 (1GB) |
| - DDR4 2CS (6): EspressoBin V7 (2GB) |
| - CUSTOMER (CUST): 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 |
| |
| - 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`` |
| |
| 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> all fip |
| |
| 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 all fip |
| |
| Supported MARVELL_PLATFORM are: |
| - a3700 (for both A3720 DB and EspressoBin) |
| - a70x0 |
| - a70x0_amc (for AMC board) |
| - a80x0 |
| - a80x0_mcbin (for MacciatoBin) |
| |
| 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 |
| a70x0 and a80x0 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 7 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. |
| |
| |
| 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 |
| |
| (2) DDR initialization library sources (mv_ddr) available at the following repository |
| (use the "mv_ddr-armada-atf-mainline" branch): |
| |
| https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git |
| |
| (3) Armada3700 tools available at the following repository (use the latest release branch): |
| |
| https://github.com/MarvellEmbeddedProcessors/A3700-utils-marvell.git |
| |
| Armada70x0 and Armada80x0 Builds require installation of an additional component |
