I think Miquel is out of office for some days, so I just checked and you 
are right, the maximum number of bad blocks should be swapped.

Actually there is also a wrong value in the GigaDevice driver: For the 
GD5F4GQ4xA it should be 80 instead of 40.

Would you mind sending a patch with a "Fixes:" tag, that fixes both, the 
Macronix and the GigaDevice driver? Or should I send one?

Thanks,
Frieder
