Subject: kernel: create bootfs partition when parsing on BCM4908
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6dd727ac24fa36ac3f23e9a5cf6781a7d1c6b797;p=openwrt%2Fstaging%2Fldir.git

kernel: create bootfs partition when parsing on BCM4908

It's helpful for accessing booting data (DTS, kernel, etc.). It has to
be used carefully as CFE's JFFS2 support is quite dumb. It doesn't
recognize deleted files and has problems handling 0 inode.
