There could be further initialization of Dataflash devices
at later time:
- Dataflash card may be plugged into the board when U-Boot is
   already running, e.g. for firmware updates.
- A Dataflash can be placed on an extension board which will
   be powered up later during system start-up. This could also
   require a Dataflash to be initialized later. Probably such
   open() function could check if the extension board is present
   and powered.

With best regards
