When I want to turn on MTD with TQM8XXL, I can't find it in kernel 2.6.12.3.
I use "MTD\Mapping drivers for chip access\CFI Flash device in physical
memory map", it seems only one partition can be used.
Thanks,
Johnson Cheng

It is up to you to define a memory map for your flash device(s) and
create appropriate partitions for this map in Linux (and probably in
U-Boot, too, using the new "mtdparts" command).
Then you can use standard commands in U-Boot (erase, cp) and in Linux
(erase_all, cp) to store any data you likein your flash.
It is *your* design. *You* must create it.
Best regards,
Wolfgang Denk
