First released by Intel in June 2013, the Enhanced Serial Peripheral Interface (“eSPI”) is designed as a replacement for the Low Pin Count (“LPC”) bus.  eSPI supports communication between Embedded Controller (EC), Baseboard Management Controller (BMC), Super-I/O (SIO) and Port-80 debug cards.  eSPI was available in the Sky Lake chipset (2015) and is available in the Kaby Lake [current] chipset.  Cannonlake will support eSPI and is slated for release the second half of 2017. Icelake is scheduled for release in 2019 and it will mark the first chipset when eSPI becomes mandatory.
