I dont see why you should need to call any "open" routine
since the dataflash is active before u-boot has even started
and does not need any initialization sequence.

You load U-boot from the dataflash to the SDRAM
so any initialization needed by the dataflash is already
done before the first U-boot instruction is executed..

Thus you search for the dataflash at boot
if support is enabled and then initialize
the datastructures, and your done with it.

I don't think anything trivial should be merged.
It should be kept as a
