It's a Numonyx M25P32 (until a couple of years ago parts of the company
were known as SP)
Here I added this:

Yes, I just didn't want to fiddle with the buffer size and all dediprog
devices I've seen have a space in the last character.
Using a 0x11 bytes big buffer would be the correct approach.

Will produce these asap.

That might be a problem, I think 32MBit are the only ones I have here at
the moment.. :-}
I'll have a look.
