By default all external CPs start with configuration address space set to 0xf200_0000. To overcome this issue, go in the loop and initialize the CP one by one, using temporary window configuration which allows to access each CP and update its configuration space according to decoding windows scheme defined for each platform. In case of cn9130 after this procedure bellow addresses will be used: CP0 - f2000000 CP1 - f4000000 CP2 - f6000000 When the re-configuration is done there is need to restore previous decoding window configuration(init_io_win).

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.
