  1. config PCH
  2. bool "Enable Platform-controller Hub (PCH) support"
  3. depends on X86 || SANDBOX
  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.
  10. config X86_PCH7
  11. bool "Add support for Intel PCH7"
  12. default y if X86
  13. help
  14. Enable this if your SoC uses Platform Controller Hub 7 (PCH7). This
  15. dates from about 2011 and is used on baytrail, for example. The
  16. PCH provides access to the GPIO and SPI base addresses, among other
  17. functions.
  18. config X86_PCH9
  19. bool "Add support for Intel PCH9"
  20. default y if X86
  21. help
  22. Enable this if your SoC uses Platform Controller Hub 9 (PCH9). This
  23. dates from about 2015 and is used on baytrail, for example. The
  24. PCH provides access to the GPIO and SPI base addresses, among other
  25. functions.
