If you do not use the NAND boot, there really no need to do so.

Since you need the NAND boot, we should enable the swapping for imx28.

The BB mark is in the page 0 of a NAND block. But the swapping can occur 
in _each_ page of
a NAND block, _NOT_ only the page 0.

I think you are confusing at these two things.
