Hi Charles,
The capacitor connected to cap_vdd_bb_mpu_iva is decoupling capacitor for processor domains. The capacitor must be placed as close as possible to the ball. The capacitor at the output is required to stabilize the voltage. The presence of this capacitor provides stable work of the processor. If the capacitor absent I could not guarantee the stable work (it is 50:50 ). As I see the schematics of other dm3730 boards the capacitor presents.
