Can you try to do this outside of the probe function?

ie. use a hash made from ptr to probe function and size (or rather base

Also, I think since the multi flashchip support went in, flashrom
continues to probe
for 512K flash chips at 0xfff80000 even though a 512K flash chip was
found at that very address
 -- This is a rather useless behavior and was introduced only recently.
If we stop probing in a certain memory range once we know that range is
reserved by a given flash chip, we can greatly reduce the probing time
again (back to what it was a while ago)
