| 2 | * linux/include/asm-arm/byteorder.h | |
| 3 | * | |
| 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 | |
