I have repeatedly objected to this patch [0][1][2] and you have 
repeatedly decided to not address my objections. I won't spend any more 
time fighting it. But I will say that you should not expect any 
guarantees that SPI NOR or SPI NAND will not break your calibration in 
the future if they decide to move the dirmap_create() call around.
