This is not really correct. On the DK you can boot from NOR flash, and then the flash is extremely important for U-Boot. But the only really critical thing is if the location and size of the environment sector mtches; as far as I can see the default location has it at offset 0x50000, i. e. already in the "big" 0x10000 uniformly sized sectors. So replacing the flashes with a top sector type should be uncritical, indeed.
