Subject: buildman: Add an option to flatten output directory trees
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=5971ab5c44cb0c32c88fcdc90a3a9b6430463c4c;p=u-boot.git

buildman: Add an option to flatten output directory trees

When building current source for a single board, buildman puts the output
in <output_dir>/current/current/<board>. Add an option to make it use
<output_dir>/<board> instead. This removes the unnecessary directories
in that case, controlled by the --no-subdirs/-N option.
