Well, obviously, the address lines are connected up such that all
accesses in that section wrap into the flash, whatever the offset is.
Unfortunately, but understandably, it makes no difference whatsoever to
the behaviour of the flash chip. I can still put it into QRY mode, where
I get the doubled QQRRYY response, but the flash is not detected any
better than it was previously.
I suppose my next best option is to try to ask the Linux kernel folk if
they have any ideas.
