Hi,

On Jul 25th in the TF-A Tech Forum:

Unification of Chain of Trust Descriptors - presented by Xialin Liu

Currently, the Chain of Trust is implemented using C data structures built into the firmware or through device tree nodes. Maintaining both formats can lead to maintenance challenges. Therefore, we are standardizing the provision of Chain of Trust descriptors exclusively via the device tree and providing a tool to convert device tree descriptors into C source files.
This approach simplifies the process, ensuring consistency and reducing the potential for errors associated with managing multiple formats.

Regards,
Olivier.
