With the transition to mailman3, the URLs of TF-A and TF-A Tests mailing lists have changed. However, we still refer to the old location, which are now dead links. Update all relevant links throughout the documentation. There is one link referring to a specific thread on the TF-A mailing list in the SPM documentation, for which I had to make a guess as to what's the equivalent mailman3 URL. The old URL scheme indicates that the thread dates from February 2020 but beyond that, I could not make sense of the thread id within the old URL so I picked the most likely match amongst the 3 emails posted on the subject in this time period.

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.
