Bus-specific drivers should use the identify method to attach themselves to nexus so interrupt can be allocated before the h/w is probed. The 'early attach' routine in openpic is used for this stage of boot. When h/w is probed, the openpic can be attached properly. It will enable interrupts allocated prior to this. END
