 * The sandpoint boards have processor modules that either have an 8240 or
 * an MPC107 host bridge on them.  These bridges have an IDSEL line that allows
 * 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
 * below.
