mkfs.jffs2 will build a _populated_ image for you, containing all the files
in the directory you specify. It's more like mkisofs/mkcramfs than
mkfs.ext2, and should probably be renamed accordingly.
If you really want to mount the image on your PC, you need to be using the
latest code which can handle byteswapping (see the #define in jffs2.h) and
load an 'mtdram' module on the PC with size and erasesize matching your
hardware. Then see http://www.handhelds.org/z/wiki/LoopBack
Don't forget the '-b' option to mkfs.jffs2.
