Developed Universal Flash Storage (UFS) support for ROCK 4D hardware within the geerlingguy/linux repository, focusing on embedded systems and kernel development using C. The work involved enabling the UFS host controller and updating the Rockchip device tree to recognize removable UFS chips, delivered as a single, well-scoped commit. This enhancement improved storage compatibility for embedded and edge devices, streamlining integration for hardware partners and supporting more reliable storage configurations in production. The changes established clear commit traceability, facilitating future upstream discussions and performance reviews, and laid the foundation for broader UFS adoption across ARM64 Rockchip platforms.
