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