11.1. TF-A Build Instructions for Marvell Platforms

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

11.1.1. Build Instructions

  1. Set the cross compiler

    > 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)

> 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)

> export SCP_BL2=path/to/mrvl_scp_bl2*.img
  1. 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

> sudo apt-get install gcc-arm-linux-gnueabi
  1. Clean previous build residuals (if any)

    > make distclean
    
  2. 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 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:
    • 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

    > 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

    > 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 MacchiatoBin)

    • t9130 (OcteonTX2 CN913x)

11.1.2. 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 Build Options document.

11.1.3. 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.

11.1.4. Tools and external components installation

11.1.4.1. 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

    > 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

    > 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-18.12” branch):
