rpaphp_add_slot – declare a hotplug slot to the hotplug subsystem. : device node of slot

This subroutine will register a hotplugable slot with the PCI hotplug infrastructure. This routine is typically called during boot time, if the hotplug slots are present at boot time, or is called later, by the dlpar add code, if the slot is being dynamically added during runtime.

If the device node points at an embedded (built-in) slot, this routine will just return without doing anything, since embedded slots cannot be hotplugged.

To remove a slot, it suffices to call rpaphp_deregister_slot().

rpaphp_enable_slot - record slot state, config pci device : target &slot

Initialize values in the slot, and the hotplug_slot info structures to indicate if there is a pci card plugged into the slot. If the slot is not empty, run the pcibios routine to get pcibios stuff correctly set up.
