hi all,
i am working on a custom board(Redwood6) using IBM ppc 405. I am using
the Montavista's kernel 2.4.17. We have one AMD flash of 4 MB and one
Intel flash of 16 MB on our board. There are 4 mtd partitions are in AMD
and Intel flash is used as storage space of 5 mtd partition.
AMD partitions
-----------------
1. Bootparams
2. Bootldr
3. kernel
4. Filesystem1
Intel partition
--------------
5. Filesystem2
In the CFI probe, the kernel detects only one flash either AMD or INTEL
(Which address we specify as window address). What i have to to do for
cfi to detect both flash devices.
Any suggestions are appreciated

This question would be best asked of the MTD folks (cc'd), but I think
you'll need a customized "map" function that recognizes these two FLASH
device types and creates the appropriate MTD sub-devices appropriately.

What Gary said.
If you poke around in drivers/mtd/maps you'll find useful examples of
such, including how to concatenate them together into one logical MTD
device and have a file system spanning them both, etc.
