From: Piotr Dymacz Date: Thu, 6 Jul 2017 16:26:23 +0000 (+0200) Subject: firmware-utils: drop mktplinkfw-kernel tool X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d72371e42bd5b8738a75a75d970bc73b90cd9839;p=openwrt%2Fstaging%2Fansuel.git firmware-utils: drop mktplinkfw-kernel tool As we can now use combined mode in "mktplinkfw" tool to generate the same header/image, this tool is no longer needed.
