Unified Silicon Interface

Integrating binary blobs that handle parts of the silicon initialization is a common technique within the open-source firmware ecosystem to retain control over parts of the code, from a SoC vendor perspective. Within the last years multiple SoC vendors defined different interfaces to communicate to those "silicon initialization code". Also different mechanisms are in place to configure those.

The Silicon Interface Design workstream has the goal to unify these interfaces and define a specification around it so that SoC vendors and (open-source) firmware projects, and their developers, have a fixed and common way to interact and configure those silicon initialization code.
