38 * Read/write a 16 bit word from flash address 'addr'.

40 * When the cpu is in little-endian mode it swizzles the address lines
41 * ('address coherency') so we need to undo the swizzling to ensure commands
42 * and the like end up on the correct flash address.
43 *
44 * To further complicate matters, due to the way the expansion bus controller

50 * | C | D | 2
