- config PCH
- bool "Enable Platform-controller Hub (PCH) support"
- depends on X86 || SANDBOX
- 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.
- config X86_PCH7
- bool "Add support for Intel PCH7"
- default y if X86
- help
- 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.
- config X86_PCH9
- bool "Add support for Intel PCH9"
- default y if X86
- help
- Enable this if your SoC uses Platform Controller Hub 9 (PCH9). This
- dates from about 2015 and is used on baytrail, for example. The
- PCH provides access to the GPIO and SPI base addresses, among other
- functions.
