help

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

Enable this if your SoC uses Platform Controller Hub 7 (PCH7). This

dates from about 2011 and is used on baytrail, for example. The
|
|
PCH provides access to the GPIO and SPI base addresses, among other
|

functions.
