You'd need three maps, three probe calls. Although I suppose you could have 
a single map driver for the first and last chips where the access calls do 
something like:
	return *(volatile __u32 *) (addr + (addr>0x400000?0x200000:0));

You probably don't want that though. Register them as three separate chips 
and then use the partition code that's been fixed to let you combine ranges 
of separate devices into one 'partition' rather than just split devices up.
