The Platform Controller Unit (PCU) is a collection of hardware blocks that are critical for 

operation including x86 legacy compatibility that is required for Windows*. These 

hardware blocks include the Intel Legacy Block (iLB), SMBus, UART, SPI and most of 

the Power Management Controller (PMC).

The PCU also implements some high-level configuration features for the BIOS/EFI boot.
