Thanks for jumping in. That's what I was trying to point out.

In fact most of the board drivers in drivers/mtd/maps could / should go away.
The reason to have one is crappy hardware, unusual chip constellations or
other anomalities.

The common case can just be solved by using the physmap driver and the command
line partition parser. Maybe we should think about an extension to physmap so
the board support code can supply an appropriate partitioning scheme along
with the chip description.

I was thinking about simliar support for the NAND driver too, but there it
turns out that the anomalities are given per design, although it should not
be an unsolvable problem.
