/*
|
||||
* 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.
