* 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
