Hi all,

On  20 Jun, this message from Benjamin Herrenschmidt echoed through cyberspace:
> We still can decide (and that's what I currently do in the kernel) that

... and multiple host bridges, like on the 9x00 (bad, two separate buses
    ? 3 slots) and 7x00/8x00 (no problem, second (fixed, video
    subsys) bus doesn't have IO devices).

struct pci_dev has void *sysdata. Can we use that for something
reasonable here? Like additional info (iobase per device, set by fixup
code)?

Michel
