As Henrik already answered, it seems that your NAND chip is not properly defined in the nand_ids table [1]. Read your NAND datasheet and add a new entry (take a look at this one [2] as an example). You should also fill the correct timing mode, though mode 0 should work correctly on all recent NANDs.
