Do we need a pullup resistor to use EXT_WAKE?

A customer is using the EXT_WAKE signal to disable a regulator that generates the Blackfin internal (core) voltage during hibernation.  They asked if they needed a pullup on the signal connecting EXT_WAKE to the ENABLE pin of their regulator to insure proper power-up.
