The matter is that the GPMI/BCH will use the OOB. Please see the page 1263
in 16.2.2 of mx28's datasheet. It shows an NAND PAGE's layout.

You may see that the OOB will be used for storing the DATA or ECC.
There will be left some space even when i enable the BCH,  it seems the 
left space can
contains the jffs2's clean marker.  It needs to be confirmed. :)
