Hi.

I have a gadget with this amd chip on it.  Whose id and layout dfn. is 
not in the jedec_probe tables.  Unfortuanately, they have _SIX_ (6) 
erase regions.  Anyone know of a reason expanding the regions[] array to 
6 is a bad idea?  Or why dealing with this chip in general is a bad idea?

-dbu.
