HELP! How to use EP8260 MTD device?

[OHMURA Yutaka]

Does no one uses EP8260 in this ML?

Now I changed my .config as follows:
> #
> # Memory Technology Devices (MTD)
> #
> CONFIG_MTD=y
> CONFIG_MTD_DEBUG=y
> CONFIG_MTD_DEBUG_VERBOSE=3
> CONFIG_MTD_PARTITIONS=y
> CONFIG_MTD_CHAR=y
> CONFIG_MTD_BLOCK=y
> CONFIG_FTL=y
> 
> #

> CONFIG_MTD_PHYSMAP=y
> CONFIG_MTD_PHYSMAP_START=FF000000
> CONFIG_MTD_PHYSMAP_LEN=FFFFFF
> CONFIG_MTD_PHYSMAP_BUSWIDTH=2
(Only enabled lines are here.)

But still kernel says 
"physmap flash device: ffffff at ff000000
CFI: Found no Physically mapped flash device at location zero
$Id: ftl.c,v 1.38 2001/09/23 21:15:12 dwmw2 Exp $"

Is the TSL kernel(2.4.7 base) really support MTD?
If someoen have any hints, please tell me.

Regards,

Yutaka
