Bad Block management routine for MTD NandFlash driver?

[Jason Chan]

Hi all,
    Any bad block management routine (eg. Invalid block table ) is 
implemented for MTD NandFlash driver?
It seems that the ECC routine is not enough for my nandflash driver. And 
I need a more robust bad block management routine for that. Should I 
implement the invalid block table by myself, or there are some already 
implemented?
