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"
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 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
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
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

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. 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
(2) DDR initialization library sources (mv_ddr) available at the following repository
(use the "master" branch):
