JFFS2 will only scan those MTD devices which you explicitly ask it to
mount. You can tell it not to by simply refraining from trying to mount
the device :)

That's odd. Are you mounting the NOR device as root and just specifying
it with 'root=/dev/mtdblock$n' on the kernel command line? If so, try
also adding 'rootfstype=cramfs' (or whatever fs it is). The kernel will
try all available file systems in the order they were linked into the
kernel image, so it's that or hack fs/Makefile to link them in the other
order. Or make JFFS2 a loadable module and load it once the rootfs is
mounted, I suppose.
