That is pretty much just a raw H-Bridge driver.  The PWM output from
the PRU will not be nearly fast enough to provide smooth operation.

I suggest you use one of the BBB's hardware PWM channels running at
about 20 KHz (the PWM frequency recommended by Pololu).  While the PWM
pulses need to be generated quickly, updates to the PWM can happen
slowly.  I suggest you write a simple user-mode Python HAL component
and use one of the available libraries to drive the hardware PWM logic.
