It doesn't matter. The caller _knows_ the blocksize setup, and must not
_ever_ ask for an erase that doesn't both start and end on block boundaries.

I hereby declare that the behaviour of the driver if this happens is
undefined. You can do what ever you like, including erasing the whole of 
the flash, all hard drives, and blowing up the machine.

I probably won't actually accept a patch which implements that. I'd take one
which has a BUG() though ;)
