 * ARM Endian-ness.  In little endian mode, the data bus is connected such
5
 * that byte accesses appear as:
6
 *  0 = d0...d7, 1 = d8...d15, 2 = d16...d23, 3 = d24...d31
7
 * and word accesses (data or instruction) appear as:
8
 *  d0...d31
9
 *
10
 * When in big endian mode, byte accesses appear as:
11
 *  0 = d24...d31, 1 = d16...d23, 2 = d8...d15, 3 = d0...d7
12
 * and word accesses (data or instruction) appear as:
13
