| Some AMD SoCs support more than one PCI segment with 256 buses. Those |
| SoCs however have a different data fabric register layout for the PCI |
| bus number decoding. SoCs that use a data fabric register pair for |
| the PCI bus number which includes the segment number must select this |
| option; SoCs that use one data fabric register for the PCI bus number |
| which doesn't include a segment number field mustn't select this. |
