Never mind those additional commits: they are commits from
u-boot/master which are needed by your branch (or more exactly, which
you have based your branch upon) and which are not (yet) in
u-boot-arm/master.

Think of them as the "common trunk of commits" shared between
u-boot/master and your master branch.

If I apply u-boot/master first, the trunk commits will be pulled in,
and laster, when I apply your branch, the trunk will already be in
place and I4ll only pull your own commits.

OTOH, if I apply your branch first, the trunk commits will be pulled in
just the same; and when later I apply u-boot/master, the trunk commits
will already be in place and I'll only pull that part of u-boot/master
which I don't yet have.

Is this clearer?
