| 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. |

| 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. |

| 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 |
