I don't know ...

here's what we do for ext2 on doc.
nftl_format /dev/mtd0 1048576 (sets up /dev/nftla to be at 1M offset)
fdisk /dev/nftla
Then create a primary partition on /dev/nftl
This will become /dev/fntla1
Then unload and reload all the modules, this seems to be needed
then mke2fs /dev/nftla1
Then the cmdline for linux includes: "root=/dev/nftla1"
I need to do this howto, sorry.
