You can use a tool called patman to prepare, check and sent patches. It creates
change logs, cover letters and patch notes. It also simplified the process of
sending multiple versions of a series.

Patman patch manager

This tool is a Python script which:
- Creates patch directly from your branch
- Cleans them up by removing unwanted tags
- Inserts a cover letter with change lists
- Runs the patches through checkpatch.pl and its own checks
- Optionally emails them out to selected people

- lists comments received on a series

For most cases of using patman for U-Boot development, patman can use the
file 'doc/git-mailrc' in your U-Boot directory to supply the email aliases
you need. To make this work, tell git where to find the file by typing
this once:

you can add a [settings] section to your .patman file. This can be used
for any command line option by referring to the "dest" for the option in
patman.py. For reference, the useful ones (at the moment) shown below

$ ./tools/patman/patman send -n
.. code-block:: bash
./tools/patman/patman send -n

there are in your series:

Similar to the above, but skip the first commit and take the next 5. This
is useful if your top commit is for setting up testing.
How to install it
=================
-----------------
The most up to date version of patman can be found in the U-Boot sources.
However to use it on other projects it may be more convenient to install it as
a standalone application. A distutils installer is included, this can be used
to install patman:
$ cd tools/patman && python setup.py install
.. code-block:: bash
cd tools/patman && python setup.py install
How to add tags
===============
---------------
To make this script useful you must add tags like the following into any
commit. Most can only appear once in the whole series.
Series-to: email / alias
Email address / alias to send patch series to (you can add this
multiple times)

RFC patches, or RESEND if you are being ignored. The patch subject
is like [RFC PATCH] or [RESEND PATCH].

Where Patches Are Sent
======================
----------------------
Once the patches are created, patman sends them using git send-email. The
whole series is sent to the recipients in Series-to: and Series-cc.
You can Cc individual patches to other people with the Patch-cc: tag. Tags
in the subject are also picked up to Cc patches. For example, a commit like
this:
this::

General points
==============
--------------
1. When you change back to the us-cmd branch days or weeks later all your
information is still there, safely stored in the commits. You don't need
to remember what version you are up to, who you sent the last lot of patches
to, or anything about the change logs.

2. If you put tags in the subject, patman will Cc the maintainers
automatically in many cases.

3. If you want to keep the commits from each series you sent so that you can
compare change and see what you did, you can either create a new branch for
each version, or just tag the branch before you start changing it:

6. It is a good idea to add the change log info as you change the commit,
not later when you can't remember which patch you changed. You can always
go back and change or remove logs from commits.
not later when you can't remember which patch you changed. You can always
go back and change or remove logs from commits.
7. Some mailing lists have size limits and when we add binary contents to
our patches it's easy to exceed the size limits. Use "--no-binary" to
generate patches without any binary contents. You are supposed to include
a link to a git repository in your "Commit-notes", "Series-notes" or
"Cover-letter" for maintainers to fetch the original commit.

8. Patches will have no changelog entries for revisions where they did not
change. For clarity, if there are no changes for this patch in the most
recent revision of the series, a note will be added. For example, a patch
