4 * 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 *  d0...d31
