Doesn't work if the banks aren't made to appear contiguous by the map
driver. The probe code can't handle it.
The case in question has something like:
--------------
| CFI chip |
--------------
| BIOS chip |
--------------
| CFI chip |
--------------
You could hack up a map driver that appears to have the two CFI chips
contiguously, and then the probe code would find them both and make a
single MTD device from them - but there was a reason why he wasn't doing
this. Perhaps the 'BIOS' bit is in fact the beginning of the second chip,
not actually a separate chip at all? I don't remember.
