Bjorn Helgaas 2fe2abf896 PCI: augment bus resource table with a list ... Previously we used a table of size PCI_BUS_NUM_RESOURCES (16) for resources forwarded to a bus by its upstream bridge. We've increased this size several times when the table overflowed. But there's no good limit on the number of resources because host bridges and subtractive decode bridges can forward any number of ranges to their secondary buses. This patch reduces the table to only PCI_BRIDGE_RESOURCE_NUM (4) entries, which corresponds to the number of windows a PCI-to-PCI (3) or CardBus (4) bridge can positively decode. Any additional resources, e.g., PCI host bridge windows or subtractively-decoded regions, are kept in a list. I'd prefer a single list rather than this split table/list approach, but that requires simultaneous changes to every architecture. This approach only requires immediate changes where we set up (a) host bridges with more than four windows and (b) subtractive-decode P2P bridges, and we can incrementally change other architectures to use the list.
