The Platform Environment Control Interface (PECI) is an interface
that provides a communication channel to Intel processors and
chipset components from external monitoring or control devices.

If you are building a Baseboard Management Controller (BMC) kernel
for Intel platform say Y here and also to the specific driver for
your adapter(s) below. If unsure say N.

This support is also available as a module. If so, the module
will be called peci.
