Sami Mujawar contributed to the zephyrproject-rtos/trusted-firmware-a repository by delivering a documentation-focused feature that clarified the packing of UUIDs in FFA manifest bindings. Using reStructuredText (rst) and leveraging strong documentation skills, Sami provided a clear, standards-aligned reference that links the FFA manifest documentation to the SMC Calling Convention, guiding developers through integration details. This work addressed ambiguity in UUID handling, improving developer onboarding and reducing integration risk. Although the contribution was limited to documentation and did not involve bug fixes, it demonstrated careful cross-repository referencing and commit traceability, supporting more reliable porting and integration of Trusted Firmware A.
