* The sandpoint boards have processor modules that either have an 8240 or

* them to respond to PCI transactions as if they were a normal PCI devices.
* However, the processor on the processor side of the bridge can not reach
* out onto the PCI bus and then select the bridge or bad things will happen
* (documented in the 8240 and 107 manuals).
* Because of this, we always skip the bridge PCI device when accessing the
* PCI bus. The PCI slot that the bridge occupies is defined by the macro
