* GPIO Test Application for Zedboard
*
* Read from GPIO: U/D/L/R/C Pushbuttons
* MIO: PushButtons (BTN8, BTN9) (Pins 50, 51)
* EMIO: DipSwitches
* Write one of these values to the GPIO LEDs
*
* MIO and EMIO are on same address
* MIO pins 0-53 are on banks 1 and 2
* EMIO are on banks 2 and 3
* MIO/EMO is initialised with a XGpioPs_Config* pointer and a XGpioPs
