pci_bus_find_capability - query for devices' capabilities : the PCI bus to query : PCI device to query : capability code

Like pci_find_capability() but works for pci devices that do not have a pci_dev structure set up yet.

Returns the address of the requested capability structure within the device's PCI configuration space or 0 in case the device does not support it.

void __devinit pci_process_bridge_OF_ranges	(	struct pci_controller *	hose,

	)

pci_process_bridge_OF_ranges - Parse PCI bridge resources from device tree : newly allocated pci_controller to be setup : device node of the host bridge : set if primary bus (32 bits only, soon to be deprecated)

This function will parse the "ranges" property of a PCI host bridge device node and setup the resource mapping of a pci controller based on its content.

Life would be boring if it wasn't for a few issues that we have to deal with here:

We can only cope with one IO space range and up to 3 Memory space ranges. However, some machines (thanks Apple !) tend to split their space into lots of small contiguous ranges. So we have to coalesce.

We can only cope with all memory ranges having the same offset between CPU addresses and PCI addresses. Unfortunately, some bridges are setup for a large 1:1 mapping along with a small "window" which maps PCI address 0 to some arbitrary high address of the CPU space in order to give access to the ISA memory hole. The way out of here that I've chosen for now is to always set the offset based on the first resource found, then override it if we have a different offset and the previous was set by an ISA hole.

Some busses have IO space not starting at 0, which causes trouble with the way we do our IO resource renumbering. The code somewhat deals with it for 64 bits but I would expect problems on 32 bits.

Some 32 bits platforms such as 4xx can have physical space larger than 32 bits so we need to use 64 bits values for the parsing
