Having a large romfs and then a relatively small jffs2 will make it boot
faster, because the jffs2 scan obviously doesn't have as much to do. But
you won't get the wear levelling - obviously the R/W bits are then limited
to the area of flash that you partitioned for jffs2.

romfs will work happily on /dev/mtdblock<n> devices, either the full
CONFIG_MTD_BLOCK device which would also allow you to update the contents
(as long as it's not mounted at the time, of course) or the smaller
CONFIG_MTD_BLOCK_RO module which provides the same device, just without
write functionality.
