* pciDevAnnounceInfo - structure used by pciBusAnnounceDevices()
*
* pciBusAnnounceDevices is called after the legacy PCI bus configuration
* has been performed. The purpose of the routine is to traverse the
* bus and find all devices which are present on the bus. For each device
* found, the bus subsystem calls vxbDeviceAnnounce() to notify the bus
* subsystem that a device is present, and establish an instance if the
* driver can be found.
*
* The pciBusAnnounceDevices() routine uses pciConfigForeachFunc() to
* traverse the PCI bus hierarchy. The information required by each
* device, in order to establish a working instance, is contained in
* the pciDevAnnounceInfo structure. This includes the PCI bus methods
* which the driver will use to access methods, as well as a vxbDev
* struct pointer to indicate the pci controller, which contains
* information about the PCI device's parent bus.
