No difference in the code. I just figured it made more sense to split them into firmware-utils and ramips bits instead of one blob. Thank you kindly for merging these. -Claudio ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
