Sandrine Bailleux 446354122c docs(threat-model): add a threat model for TF-A with Arm CCA ... Arm Confidential Compute Architecture (Arm CCA) support, underpinned by Arm Realm Management Extension (RME) support, brings in a few important software and hardware architectural changes in TF-A, which warrants a new security analysis of the code base. Results of this analysis are captured in a new threat model document, provided in this patch. The main changes introduced in TF-A to support Arm CCA / RME are: - Presence of a new threat agent: realm world clients. - Availability of Arm CCA Hardware Enforced Security (HES) to support measured boot and trusted boot. - Configuration of the Granule Protection Tables (GPT) for inter-world memory protection. This is only an initial version of the threat model and we expect to enrich it in the future.
