Why not use
compatible = "micron,M29W256G", "cfi-flash";
since that's what's on the SABRE-AI board?
we may use other NOR. :)
so it's better do not bind the specific NOR, even for SABRE-AI.
I even tested Spanion NOR in the SABRE-AI boards.

Shawn Guo:
I do not see how this driver depends on MTD_PHYSMAP_OF.
physmap_of is the module that provides the mapping driver for the cfi-flash that
associates memory with the "reg" properties of the nor node. However, since
EIM can also attach Bluetooth module or GPS, the EIM driver itself certainly does not
depend on the map module.
ok.
i will remove it in next version.
thanks for the comment and review.
