* On PIP/MIP405 we have 3 (4) possible boot mode
*
* - Boot from Flash (Flash CS = CS0, MPS CS = CS1)
* - Boot from MPS (Flash CS = CS1, MPS CS = CS0)
* - Boot from PCI with Flash map (Flash CS = CS0, MPS CS = CS1)
* - Boot from PCI with MPS map (Flash CS = CS1, MPS CS = CS0)
* 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.
* update_flash_size() will fix in wrong values in the flash_info structure,
* misc_init_r() will fix the values in the board info structure
