/*
 *  Define a 'struct fl_map' init set for each flash area on the target.
 */

/* Note! Not requiered but prefered, sort in ascending address order */

/*
 * Power4e has two different maps depending on which device is mapped
 * at 0xfff00000. See tgt_flashmap() on how to select the correct one
 */

/*
 *  NOTE about 'width' codes. Usually the 'width' is the number of
 *  bytes that are accessed at the same time while the next value
 *  is the number of chips. Bytes per chips can be found by dividing
 *  'width' with 'chips'. The code 9 for width is special to handle
 *  how the power4e addresses the AMD single chip when not mapped as
 *  boot device.
