I believe you can just use a single output pin set to generate an IRQ back to yourself.

Can you explain a little bit more?

Yes , I passed over the reference again today...

In SPRU988B, section 2.10.3 it says you can do this.

"Note that the direction of the GPIO signal does not have to be an input for the interrupt event generation to work. When a GPIO signal is configured as an output, the software can change the GPIO signal state and, in turn, generate an interrupt. This can be useful for debugging interrupt signal connectivity."

Hopefully that is the sort of thing you meant.
