Comment (by Jeffrey Hill):

 Considering this further, if it was a plug-and-play PCI system, then one
 would also need to make certain that the address range was disabled in the
 bridge if the topology changed in way that caused the address range in a
 particular bridge to become empty in a 2nd or 3rd scan after power on.

 The scenario that I am concerned about would be if someone, for example,
 removed a card with the power on and then soft rebooted RTEMS. That might
 happen for example if a PCI Express over cable device was turned off.

 This sounds like a very legitimate concern in our situation so I will
 submit another suggested path. standby...
