  49  * The flash init is the first board specific routine which is called
  50  * after code relocation (running from SDRAM)
  51  * The first thing we do is to map the Flash CS to the Flash area and
  52  * the MPS CS to the MPS area. Since the flash size is unknown at this
  53  * point, we use the max flash size and the lowest flash address as base.
  54  *
  55  * After flash detection we adjust the size of the CS area accordingly.
  56  * update_flash_size() will fix in wrong values in the flash_info structure,
  57  * misc_init_r() will fix the values in the board info structure
