|
|

* The flash init is the first board specific routine which is called
|

* after code relocation (running from SDRAM)
|
|
||||||
* The first thing we do is to map the Flash CS to the Flash area and
|

* the MPS CS to the MPS area. Since the flash size is unknown at this
|
|

* point, we use the max flash size and the lowest flash address as base.
|
|

*
|
|
||||||
* After flash detection we adjust the size of the CS area accordingly.
|
|
||||||
* The board_init_r will fill in wrong values in the board init structure,
|
|
||||||
* but this will be fixed in the misc_init_r routine:
|
|
||||||
* bd->bi_flashstart=0-flash_info[0].size
