Is this a 16-bit NAND? If so, the first two bytes have to be 0xffff, unless the controller driver defines the bad block pattern differently.
It is an 8 bit nand. The badblock patern can be redefined by the controller driver to be different from the one in nand_base.c ? Do you have an example of this ?
look at the Blackfin nand driver (in u-boot and linux). we have to override the badblock layout because our on-chip boot rom expects something other than what linux uses.
But be careful when doing this -- it really should match what manufacturers will write.
If it's an 8-bit NAND, I don't see why it would be looking for anything but the first byte by default. Overriding should not be necessary.
