Right, this is also correct. Anyway, BOOT_FROM is used to get the offset
inside the storage, and only to be as much flexible as possible, each
storage has defined its own offset. However, Freescale uses the same
offset (0x400) for most storages (NAND, SD..) and another one for NOR or
OneNAND  (0x1000). Maybe it is easier to have only this two cases.

Best regards,
Stefano
