Subject: ar71xx: fix seama factory type image generation.
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fsvn-archive%2Farchive.git;a=commitdiff_plain;h=9073d18fad5337e23b83896a64d8ff3fab1a711c

ar71xx: fix seama factory type image generation.

Currently JFFS2 end-of-filesystem marker 0xdeadc0de is included the
computation of image's MD5 checksum as part of the seama header.  But
OpenWrt will erase blocks including and after the marker thus
invalidating the checksum after the first boot.
