- * initPciBusState() - fill out the BusAccRec for a PCI bus.
- * Theory: each bus is associated with one bridge connecting it
- * to its parent bus. The address of a bridge is therefore stored
- * in the BusAccRec of the bus it connects to. Each bus can
- * have several bridges connecting secondary buses to it. Only one
- * of these bridges can be open. Therefore the status of a bridge
- * associated with a bus is stored in the BusAccRec of the parent
- * the bridge connects to. The first member of the structure is
- * a pointer to a function that open access to this bus. This function
- * receives a pointer to the structure itself as argument. This
- * design should be common to BusAccRecs of any type of buses we
- * support. The remeinder of the structure is bus type specific.
- * In this case it contains a pointer to the structure of the
- * parent bus. Thus enabling access to a specific bus is simple:
- * 1. Close any bridge going to secondary buses.
- * 2. Climb down the ladder and enable any bridge on buses
- *    on the path from the CPU to this bus.
