* CAM5200 is a TQM5200B based board. Additionally it also features
* a NIOS cpu. The NIOS CPU peripherals are accessible through MPC5xxx
* Local Bus on CS5. This includes 32 bit wide RAM and SRAM as well as
* 16 bit wide flash device. Big Endian order on a 32 bit CS5 makes
* access to flash chip slightly more complicated as additional byte
* swapping is necessary within each 16 bit wide flash 'word'.
*
* This driver's task is to handle both flash devices: 32 bit TQM5200B
* flash chip and 16 bit NIOS cpu flash chip. In the below
* flash_addr_table table we use least significant address bit to mark
* 16 bit flash bank and two sets of routines *_32 and *_16 to handle
* specifics of both flashes.
