Currently, PowerPC PowerNV platform utilizes ppc_md.pcibios_fixup(), which is called for once after PCI probing and resource assignment are completed, to allocate platform required resources for PCI devices: PE#, IO and MMIO mapping, DMA address translation (TCE) table etc. Obviously, it's not hotplug friendly. This adds weak function pcibios_setup_bridge(), which is called by pci_setup_bridge(). PowerPC PowerNV platform will reuse the function to assign above platform required resources to newly plugged PCI devices during PCI hotplug in subsequent patches.
