++ * Read/write a 16 bit word from flash address 'addr'.
++ *
++ * When the cpu is in little-endian mode it swizzles the address lines
++ * ('address coherency') so we need to undo the swizzling to ensure commands
++ * and the like end up on the correct flash address.
++ *
++ * To further complicate matters, due to the way the expansion bus controller
++ * handles 32 bit reads, the byte stream ABCD is stored on the flash as:
++ * D15 D0
++ * +---+---+
++ * | A | B | 0
++ * +---+---+
++ * | C | D | 2
++ * +---+---+
++ * This means that on LE systems each 16 bit word must be swapped. Note that
++ * this requires CONFIG_MTD_CFI_BE_BYTE_SWAP to be enabled to 'unswap' the CFI
++ * data and other flash commands which are always in D7-D0.
