No, please don't use a branch. Never ever. This makes the build
non-reproducible. And also means that once a
linux-linux-3.18-at91.tar.gz tarball has been created in $(DL_DIR), it
is never redownloaded even if the branch is updated.

So please do like Ryan said: use a tag or a commit ID. Feel free to
update this commit ID or tag as often as you want by sending patches,
but don't use a branch name.

Thanks,

Thomas
