Can I use all PWM pins of BBB at a time for controlling 8 servo motors?

I just got a BBB and I need to control 8 digital servo motors. How can I do so? So far I can see that only 4 PWM pins can be enabled, then what are the functions of the other 4?

I have 4 Hitec HS-7950TH servos [ServoCity Link:http://www.servocity.com/html/hs-7950th_servo.html] and 4 Hitec HS-5056MG [ServoCity Link: http://www.servocity.com/html/hs-5056mg_servo.html] servo motors to control.

To summarize,

Q. I need to control 8 digital servo motors at a time independently using a Beaglebone Black, is it possible using the 8 PWM pins, if so then how can I do that?

Thanks.
