* 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

|
||
|
|
* (documented in the 8240 and 107 manuals).

* Because of this, we always skip the bridge PCI device when accessing the
