0020 /* In general GPIOs of BeagleBone Black/White can be addressed
0021  * using two 46-pin dual-row expansion connectors P9 and P8,
0022  * which are also known as Expansion A and Expansion B Connectors,
0023  * respectively.
0024  *
0025  * Each Expansion Connector consists of 23 pins. So 2x23 pins would
0026  * be available. It has 4 GPIO Banks each consists of 32 pins each.
0027  * Toatal number of pins are 128 (32x4).
0028  *
0029  * So for mapping between generalized pin name and the unique pin
0030  * numbers in this header file Macros are declared.
