*  Flash and Board Configuration
*
*  The driver supports also different configurations of the flash chips
*  on the board. In each configuration a new data Type called
*  'FLASHDATA' is defined to match the current CPU data bus width.
*  This data type is then used for all accesses to the memory.
*
*  The different options (defines) are explained below:
