First create your to be filesystem in a directory (call it e.g. img_dir),
then run "mkfs.jffs img_dir > fs.jffs", this creates an image fs.jffs that
you can copy to your flash (in the case of an mtdram flash, just do "cat
fs.jffs > /dev/mtd0". Then mount the flash "mount -t jffs /dev/mtdblock0
Then just go to /mnt/jffs and play around with the filesystem. Not
everything works well right now, rename isn't implemented, and unlink
seems to have some problems.
Also note that the default size of the mtdram device is 2 meg, if you want
a different size you have to change a define in the mtdram.c code.
