Subject: buildman: Allow selection of the number of commits to build
X-Git-Tag: v2014.10-rc2~126
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=3b74ba5f1af147df0aea243976f7064a2734d551;p=u-boot

buildman: Allow selection of the number of commits to build

It is useful to be able to build only some of the commits in a branch. Add
support for the -c option to allow this. It was previously parsed by
buildman but not implemented.
