# CFE expects a single JFFS2 partition with cferam and kernel. However,
# it's possible to fool CFE into properly loading both cferam and kernel
# from two different JFFS2 partitions by adding dummy files (see
# cfe-jffs2-cferam and cfe-jffs2-kernel).
# Separate JFFS2 partitions allow upgrading openwrt without reflashing cferam
# JFFS2 partition, which is much safer in case anything goes wrong.
