The INFTL driver completely ignores the bad block table. Running
eraseall wipes the bad block table. 

This is a bad thing. I have disabled the support for these devices

No, the driver needs to be updated to understand and enforce the BBT.

No, we broke them by erasing them.

The Bad Block Table is fairly simple. It won't be that hard to implement
proper support for it.
