| Firmware Framework for Armv8-A |
| ============================== |
| The |FF-A| specification defines a software architecture that isolates Secure world firmware images from each other. The |
| specification defines interfaces that standardize communication between various images. This includes communication |
| between images in the Secure world and Normal world. |
| |
| The Trusted Services project includes service providers that may be deployed within FF-A S-EL0 secure partitions. This |
| includes service providers that form the security foundations needed for meeting PSA Certified requirements. Other secure |
| partitions are available such as the SMM Gateway to provide Secure world backing for UEFI services. |
| |
| The component :ref:`libsp` captures helpful abstractions to allow easy FF-A compliant S-EL0 SP development. S-EL0 SPs |
| are SPMC agonistic and can be used with an SPMC running in any higher secure exception level (S-EL1 - S-EL3). |
