Narrative:

After the before takeoff checklist was completed and configuration checked ok we began the takeoff roll and a master warning spoiler config message appeared and we aborted the takeoff. The captain checked the flight control page and noted that all spoilers had deployed during takeoff roll. We called maintenance and were advised to return to the gate and deplane. System malfunctioned and spoilers deployed un-commanded during takeoff roll.
