(Doing this from memory, better check it yourself)

The message you quoted it printed out before the actual probing takes
place. There will be another message, if either the probing fails or
it detects more than one chip in the provided range. It will not
however print another message, if all goes well.
You should edit drivers/mtd/maps/physmap.c and add an unconditional
printk after the ioremap and after the actual probe, to see, which one
fails. My bet is the ioremap.
