Cell Configuration Ring

The Cell Configuration ring is sent to the Cell BE processor via an SPI bus from syscon. It is used to configure basic processor settings in preparation for booting.

Sample

This data was captured from the SPI bus connecting CELL to SYSCON and parsed as per the Cell BE 90nm HIG. See the full SPI dump for more boot-time communication over SPI.
