Developed a secure firmware update authorization workflow for the tianocore/edk2-platforms repository, focusing on embedded systems and firmware development using C. The work introduced a new FIT Record Type 0x1E, enabling the BIOS to locate the VAB Authorization Code Patch manifest and request authorization from the security controller before applying updates. This approach strengthened update integrity by ensuring only authorized firmware changes are applied. The developer refined the manifest structure and added a supporting macro, improving clarity and reducing future maintenance overhead. The contribution emphasized system architecture best practices, prioritizing security and maintainability in the firmware update process.
