2 bool "Enable Platform-controller Hub (PCH) support"
3 depends on X86 || SANDBOX
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
12 bool "Add support for Intel PCH7"
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
21 bool "Add support for Intel PCH9"
24 Enable this if your SoC uses Platform Controller Hub 9 (PCH9). This
25 dates from about 2015 and is used on baytrail, for example. The
26 PCH provides access to the GPIO and SPI base addresses, among other
