+ * pci_process_bridge_OF_ranges - Parse PCI bridge resources from device tree
+ * @hose: newly allocated pci_controller to be setup
+ * @dev: device node of the host bridge
+ * @primary: 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

+ *      - bogus I/O addresses above 64K used

+ *        shared between expansion ROMs and other resource regions, it's
+ *        at least dangerous)
+ *
+ *  Our solution:
+ *      (1) Allocate resources for all buses behind PCI-to-PCI bridges.
+ *          This gives us fixed barriers on where we can allocate.
+ *      (2) Allocate resources for all enabled devices.  If there is
+ *          a collision, just mark the resource as unallocated. Also
+ *          disable expansion ROMs during this step.
+ *      (3) Try to allocate resources for disabled devices.  If the
+ *          resources were assigned correctly, everything goes well,
+ *          if they weren't, they won't disturb allocation of other
+ *          resources.
+ *      (4) Assign new addresses to resources which were either
+ *          not configured at all or misconfigured.  If explicitly

- *  keep as much of the original configuration as possible, but tweak it
- *  when it's found to be wrong.
- *
- *  Known BIOS problems we have to work around:
- *      - I/O or memory regions not configured
- *      - regions configured, but not enabled in the command register
- *      - bogus I/O addresses above 64K used
- *      - expansion ROMs left enabled (this may sound harmless, but given
- *        the fact the PCI specs explicitly allow address decoders to be
- *        shared between expansion ROMs and other resource regions, it's
- *        at least dangerous)
- *
- *  Our solution:
- *      (1) Allocate resources for all buses behind PCI-to-PCI bridges.
- *          This gives us fixed barriers on where we can allocate.
- *      (2) Allocate resources for all enabled devices.  If there is
- *          a collision, just mark the resource as unallocated. Also
- *          disable expansion ROMs during this step.
- *      (3) Try to allocate resources for disabled devices.  If the
- *          resources were assigned correctly, everything goes well,
- *          if they weren't, they won't disturb allocation of other
- *          resources.
- *      (4) Assign new addresses to resources which were either
- *          not configured at all or misconfigured.  If explicitly
- *          requested by the user, configure expansion ROM address
