* The AT91RM9200 GPIO's are spread across four 32-bit ports A-D.
* To make it easier to interface with them and to eliminate the need
* to track which GPIO is in which port, we convert the Port x, Bit y
* into a single GPIO number 0 - 127.
*
* Board specific defines will assign the board level signal to a
* virutal GPIO.
