Current binary wtptp/linux/tbb_linux which is specified in $(DOIMAGETOOL) variable points to external pre-compiled Marvell x86_64 ELF linux binary from A3700-utils-marvell WTP repository. It means that currently it is not possible to compile TF-A for A3720 on other host platform then linux x86_64. Part of the A3700-utils-marvell WTP repository is also source code of $(DOIMAGETOOL) TBB_Linux tool. This change adds support for building $(DOIMAGETOOL) also for a3k platform. After running $(MAKE) at appropriate subdirectory of A3700-utils-marvell WTP repository, compiled TBB_linux tool will appear in WTP subdirectory wtptp/src/TBB_Linux/release/. So update also $(DOIMAGETOOL) variable to point to the correct location where TBB_linux was built. To build TBB_linux it is required to compile external Crypto++ library which is available at: https://github.com/weidai11/cryptopp.git User needs to set CRYPTOPP_PATH option to specify path to that library. After this change it is now possible to build whole firmware for A3720 platform without requirement to use pre-compiled/proprietary x86_64 executable binaries from Marvell.

Trusted Firmware-A
Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.
TF-A implements Arm interface standards, including:
- Power State Coordination Interface (PSCI)
- Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)
- SMC Calling Convention
- System Control and Management Interface (SCMI)
- Software Delegated Exception Interface (SDEI)
The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.
In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.
Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
