/*
* 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.
