Even though the FVP and FPGA are meant to be identical their RoS's (rest of system) are different. Factor these in so the device tree works for both. The differences are: * addresses of GIC and UART * displays (FPGA uses 4k) * ethernet devices and SD card (it's non removable on the FPGA) Their frequencies are also different. The FVP simulates certain frequencies but isn't very sensitive when we disregard them. To keep code similar, update them with the FPGA values. This keeps working on FVP even if slightly incorrect. Also add an option for the DPU to either use fixed clocks or SCMI set clocks, hidden behind a flag. This is useful during bringup and because SCMI may not necessarily work on FPGA.

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.
