Michael Holland developed a secure firmware update authorization workflow for the tianocore/edk2-platforms repository, focusing on embedded systems and firmware development using C. He introduced a new FIT Record Type 0x1E, allowing the BIOS to locate the VAB Authorization Code Patch manifest and request authorization from the security controller before applying updates. This approach enhanced system architecture by reducing integration risk and future maintenance overhead. Michael refined the manifest structure and added a supporting macro to improve clarity and correctness. His work addressed the need for stronger firmware update integrity, delivering a well-scoped feature with careful attention to maintainability and security.
