I mean the PCIEPORTBUS option which depends on PCI_GOMMCONFIG or PCI_GOANY. I assume that due to PCI_MMCONFIG / PCI_GOMMCONFIG mismatch it's not available on x86_64.

PCI access mode on x86_64
Hi! Is there a reason why "PCI access mode" config option isn't available for x86_64? Due to this, PCIE config options aren't available either.
