The readme.rst file in the project root is the front-page that is displayed on Github and if viewing the TF-A repository on git.trustedfirmware.org in the "about" view. It now contains a small amount of stub content, and directs readers to the ReadTheDocs documentation via trustedfirmware.org/docs/tf-a. The Github renderer is displaying the content fine but the cgit viewer displays some "backlink" errors because some content substitutions were left in place (terms surrounded by pipe symbols), e.g. |TF-A|. This patch removes those substitutions, that are not supported by cgit, and also updates one heading to clarify where to find the new docs.

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.
