Alright. This starts making more sense. I still say NACK, as the name
for that function is obviously very wrong then.
If the erase sector function works on several chips, even from different
generations, it should not carry the name of one specific chip.

If we find a good name for it, that makes clear when supporters of new
chips can use it, I suggest lets commit your patches.
