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