There are several ways to definie partitions on an MTD device. Make sure yo=
u=20
enable the 'MTD partitioning support' option and have a look at 'RedBoot=20
partition table parsing' and 'Command line partition table parsing':

Device Drivers

    [*] MTD partitioning support

Another option is to hardcode the partition table in the platform data for =
the=20
physmap driver.
