Blink

	/*
	Toggle GPIO pins / make a LED blink via manipulating BBB registers. Why? Because you need really fast I/O toggling and don't want to use the PRU.

	Step 1: Make sure selected pin is set to output. If not create a device tree overlay, include pins you need.

	What's the device tree? http://xillybus.com/tutorials/device-tree-zynq-1

	And a device tree overlay ....
