This patch pulls the PCI-related junk out of struct device_node and puts it in a separate structure, struct pci_dn. The device_node now just has a void * pointer in it, which points to a struct pci_dn for nodes that represent PCI devices. It could potentially be used in future for device-specific data for other sorts of devices, such as virtual I/O devices. Signed-off-by: Paul Mackerras <paulus@samba.org>
