It makes sense to enable CONFIG_PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT by default (when possible by dependencies) to take advantages of all 256 PCI buses on each PCI domain, like it is already on all other kernel architectures.

So system could have only 256 PCI buses independently of available -- 2.20.1
