Right, it didn't have a merge command, just a branch:
$ cat meta/cfg/kernel-cache/features/eg20t/eg20t.scc
# changes should be staged on "eg20t"
git branch eg20t master
kconf hardware eg20t.cfg
Still, including this scc brought in the eg20t branch. Perhaps if the
branch name exists the branch command does a merge? Bug?
I've confirmed this reverting to 3.10.10 happens in the do_patch()
task, but I don't know where or why yet.
