From: Simon Glass Date: Fri, 6 Feb 2015 05:06:15 +0000 (-0700) Subject: buildman: Allow comparison of build configuration X-Git-Tag: v2015.07-rc1~121^2~3 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=843312dcdd942dc1d7d9009863b04340287326e0;p=oweals%2Fu-boot.git buildman: Allow comparison of build configuration It is useful to be able to see CONFIG changes made by commits. Add this feature to buildman using the -K flag so that all CONFIG changes are reported. The CONFIG options exist in a number of files. Each is reported individually as well as a summary that covers all files. The output shows three parts: green for additions, red for removals and yellow for changes.
