4	help
5	  Most x86 chips include a PCH which is responsible for handling
6	  parts of the system not handled by that CPU. It supersedes the
7	  northbridge / southbridge architecture that was previously used. The
8	  PCH allows for higher performance since the memory functions are
9	  handled in the CPU.

15	  Enable this if your SoC uses Platform Controller Hub 7 (PCH7). This
16	  dates from about 2011 and is used on baytrail, for example. The
17	  PCH provides access to the GPIO and SPI base addresses, among other
18	  functions.
