Thermal Reporting to an External Device

To support a platform EC that is managing the system thermals, the PCH provides the ability for an external device to read the PCH temperature over SMLink1 or over eSPI interface. The EC will issue an SMBus read or 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 is not enabled yet. The EC must be connected to SMLink1 for thermal reporting support.
