Create, register( and implicitly invoke) fconf_populate_topology() function which extracts the topology related properties from dtb into the newly created fconf based configuration structure 'soc_topology'. Appropriate libfdt APIs are added to jmptbl.i file for use with USE_ROMLIB build feature. A new property which describes the power domain levels is added to the HW_CONFIG device tree source files. This patch also fixes a minor bug in the common device tree file fvp-base-gicv3-psci-dynamiq-common.dtsi As this file includes fvp-base-gicv3-psci-common.dtsi, it is necessary to delete all previous cluster node definitons because DynamIQ based models have upto 8 CPUs in each cluster. If not deleted, the final dts would have an inaccurate description of SoC topology, i.e., cluster0 with 8 or more core nodes and cluster1 with 4 core nodes.

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.
