What is recommended way to partition mtdram device

What is recommended way to partition mtdram device

[MikeW]

I require a partitioned mtdram device for system emulation purposes.

The documentation says that the ways to partition an MTD device are:
1) boot cmd line
2) table of data in device
3) create a map driver

If mtdram is to be loaded with modprobe (desktop Linux), that rules out 1).

So can I create partitions by dd-ing a partition table at the start of the
device ?
Can I create a map driver for the device to describe the partitions ?

Thanks,
MikeW

Finally used '--bind' mount option to remount different parts
of the current filesystem ('/opt/mtdblock0...n').

Allowed initial testing of the filesystem mounting and partition
allocation.

Just a simple compile-time #define to switch between
/opt/mtdblockN -> /dev/mtdblockN
flags=MS_BIND -> 0
fstype="" -> "JFFS2"

Good luck.
