Intel processors provide access for various services designed to support processor and DRAM thermal management, platform manageability and processor interface tuning and diagnostics. Those services are available via the Platform Environment Control Interface (PECI) that provides a communication channel between the processor and the Baseboard Management Controller (BMC) or other platform management device. This change introduces PECI subsystem by adding the initial core module and API for controller drivers.
