[PATCH 5/9] PCI: consolidate the PCI_DOMAINS and PCI_DOMAINS_GENERIC config options
Christoph Hellwig

Fri Nov 16 06:05:33 AEDT 2018
Move the definitions to drivers/pci and let the architectures select
them. Two small differences to before: PCI_DOMAINS_GENERIC now selects
PCI_DOMAINS, cutting down the churn for modern architectures. As the
only architectured arm did previously also offer PCI_DOMAINS as a user
visible choice in addition to selecting it from the relevant configs,
this is gone now.
