This new target builds boot-image.bin binary as described in documentation. This image does not contain WTMI image and therefore WTP repository is not required for building. Having ability to build just this boot-image.bin binary without full flash-image.bin is useful for A3720 Turris MOX board which does not use Marvell's WTP and a3700_utils. To reduce duplicity between a8k and a3k code, define this new target and also definitions for $(BUILD_PLAT)/$(BOOT_IMAGE) in common include file marvell_common.mk. For this purpose it is needed to include plat/marvell/marvell.mk file from a3700_common.mk unconditionally (and not only when WTP is defined). Now when common file plat/marvell/marvell.mk does not contain definition for building $(DOIMAGETOOL), it is possible to move its inclusion at the top of the a3700_common.mk file.

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.
