Linux Kernel MTD question

[JohnsonCheng]

Yes. You are right. It's design by myself.
But I meet a problem. If I have three configuration files, A.conf, B.conf
and C.conf, then I hope save them in one of partitions of MTD,
0x005C0000-0x10000000.
Two questions:
1. How to build these configuration files into an image for U-boot with
mkimage?
2. In kernel, how to get these data? I use "mount /dev/mtd4 /mnt", but it
failed by block device required.

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.
