Universal Payload (UPL) is an upcoming Industry Standard for firmware components. UPL is designed to improve interoperability within the firmware industry, allowing mixing and matching of projects with less friction and fewer project-specific implementations. UPL is cross-platform, supporting ARM, x86 and RISC-V initially.
This series provides some initial support for this, for comment only.
