OK. I'll add the comment and push.

The reason is without that when we want to say erase a NAND block, it will give weird outputs like erasing block at 0x00000000.

So basically the MTD NAND driver will find the bad block but we get this incorrect message as this option is not set.

Other symptoms are after for e.g we complete an erase NAND operation, we will get a message which says, 0x4026432% completed or something like that.

Thanks,
Sandeep
