Thermal Reporting to EC

To support a platform EC that is managing the system thermals, the processor provides the ability for the EC to read the processor temperature over eSPI. If enabled, Power Management will drive the temperature directly to the eSPI units. The EC will issue an eSPI OOB Channel request and receives a single byte of data, indicating a temperature between 0°C and 127°C, where 255 (0xFF) indicates that the sensor isn’t enabled yet. The EC must be connected to eSPI for thermal reporting support.
