From: Hauke Mehrtens Date: Sat, 14 Apr 2018 21:00:12 +0000 (+0200) Subject: tools/mkimage: update to version 2018.03 X-Git-Tag: v18.06.0-rc1~374 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b13e981d72c14ba4c39f85f0d24a8f7947a1b2c4;p=openwrt%2Fstaging%2Fchunkeey.git tools/mkimage: update to version 2018.03 This activates support for fit images and some other new mkimage features. Some of the patches were applied upstream and could be removed.
