Maybe the following logic for getting proper PCI addresses would work:
1.) Use stuff like pci_module_init() to find and register the Universe
device (using standard PCI functions to find the Tundra device).
2.) Determine its PCI bus from the pci_dev structure.
3.) Use the resource[] vector associated with that bus to request a set
of PCI addresses on that bus.
This should be portable and clean, and always return a set of proper PCI
addresses usable by the Tundra Universe, at least AFAIK from looking at
include/linux/pci.h and drivers/pci/pci.c.
Since you already use the PCI configuration word mechanism and device
IDs this shouldn't be too hard to adapt to.
What do you think?
With kind regards,
Oliver Korpilla
