+What is this?
+=============
+
+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
+
+It is intended to automate patch creation and make it a less
+error-prone process. It is useful for U-Boot and Linux work so far,
+since it uses the checkpatch.pl script.
+
+It is configured almost entirely by tags it finds in your commits.
+This means that you can work on a number of different branches at
+once, and keep the settings with each branch rather than having to
+git format-patch, git send-email, etc. with the correct parameters
+each time. So for example if you put:
+
+Series-to: fred.blogs@napier.co.nz
+
+in one of your commits, the series will be sent there.
+
+
+How to use this tool
+====================
+
+This tool requires a certain way of working:
+
+- Maintain a number of branches, one for each patch series you are
+working on
+- Add tags into the commits within each branch to indicate where the
+series should be sent, cover letter, version, etc. Most of these are
+normally in the top commit so it is easy to change them with 'git
+commit --amend'
+- Each branch tracks the upstream branch, so that this script can
+automatically determine the number of commits in it (optional)
+- Check out a branch, and run this script to create and send out your
+patches. Weeks later, change the patches and repeat, knowing that you
+will get a consistent result each time.
+
+
+How to configure it
+===================
+
+For most cases patman will locate and use the file 'doc/git-mailrc' in
+your U-Boot directory. This contains most of the aliases you will need.
+
+To add your own, create a file ~/.config/patman directory like this:
+
+>>>>
+# patman alias file
+
+[alias]
+me: Simon Glass <sjg@chromium.org>
+
+u-boot: U-Boot Mailing List <u-boot@lists.denx.de>
+wolfgang: Wolfgang Denk <wd@denx.de>
+others: Mike Frysinger <vapier@gentoo.org>, Fred Bloggs <f.bloggs@napier.net>
+
+<<<<
+
+Aliases are recursive.
+
+The checkpatch.pl in the U-Boot tools/ subdirectory will be located and
+used. Failing that you can put it into your path or ~/bin/checkpatch.pl
+
+
+How to run it
+=============
+
+First do a dry run:
+
+$ ./tools/scripts/patman/patman -n
+
+If it can't detect the upstream branch, try telling it how many patches
+there are in your series:
+
+$ ./tools/scripts/patman/patman -n -c5
+
+This will create patch files in your current directory and tell you who
+it is thinking of sending them to. Take a look at the patch files.
+
+$ ./tools/scripts/patman/patman -n -c5 -s1
+
+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 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)
+
+Series-cc: email / alias, ...
+ Email address / alias to Cc patch series to (you can add this
+ multiple times)
+
+Series-version: n
+ Sets the version number of this patch series
+
+Series-prefix: prefix
+ Sets the subject prefix. Normally empty but it can be RFC for
+ RFC patches, or RESEND if you are being ignored.
+
+Cover-letter:
+This is the patch set title
+blah blah
+more blah blah
+END
+ Sets the cover letter contents for the series. The first line
+ will become the subject of the cover letter
+
+Series-notes:
+blah blah
+blah blah
+more blah blah
+END
+ Sets some notes for the patch series, which you don't want in
+ the commit messages, but do want to send, The notes are joined
+ together and put after the cover letter. Can appear multiple
+ times.
+
+ Signed-off-by: Their Name <email>
+ A sign-off is added automatically to your patches (this is
+ probably a bug). If you put this tag in your patches, it will
+ override the default signoff that patman automatically adds.
+
+ Tested-by: Their Name <email>
+ Acked-by: Their Name <email>
+ These indicate that someone has acked or tested your patch.
+ When you get this reply on the mailing list, you can add this
+ tag to the relevant commit and the script will include it when
+ you send out the next version. If 'Tested-by:' is set to
+ yourself, it will be removed. No one will believe you.
+
+Series-changes: n
+- Guinea pig moved into its cage
+- Other changes ending with a blank line
+<blank line>
+ This can appear in any commit. It lists the changes for a
+ particular version n of that commit. The change list is
+ created based on this information. Each commit gets its own
+ change list and also the whole thing is repeated in the cover
+ letter (where duplicate change lines are merged).
+
+ By adding your change lists into your commits it is easier to
+ keep track of what happened. When you amend a commit, remember
+ to update the log there and then, knowing that the script will
+ do the rest.
+
+Cc: Their Name <email>
+ This copies a single patch to another email address.
+
+Various other tags are silently removed, like these Chrome OS and
+Gerrit tags:
+
+BUG=...
+TEST=...
+Change-Id:
+Review URL:
+Reviewed-on:
+Reviewed-by:
+
+
+Exercise for the reader: Try adding some tags to one of your current
+patch series and see how the patches turn out.
+
+
+Where Patches Are Sent
+======================
+
+Once the patches are created, patman sends them using gti 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 Cc: tag. Tags in the
+subject are also picked up to Cc patches. For example, a commit like this:
+
+>>>>
+commit 10212537b85ff9b6e09c82045127522c0f0db981
+Author: Mike Frysinger <vapier@gentoo.org>
+Date: Mon Nov 7 23:18:44 2011 -0500
+
+ x86: arm: add a git mailrc file for maintainers
+
+ This should make sending out e-mails to the right people easier.
+
+ Cc: sandbox, mikef, ag
+ Cc: afleming
+<<<<
+
+will create a patch which is copied to x86, arm, sandbox, mikef, ag and
+afleming.
+
+
+Example Work Flow
+=================
+
+The basic workflow is to create your commits, add some tags to the top
+commit, and type 'patman' to check and send them.
+
+Here is an example workflow for a series of 4 patches. Let's say you have
+these rather contrived patches in the following order in branch us-cmd in
+your tree where 'us' means your upstreaming activity (newest to oldest as
+output by git log --oneline):
+
+ 7c7909c wip
+ 89234f5 Don't include standard parser if hush is used
+ 8d640a7 mmc: sparc: Stop using builtin_run_command()
+ 0c859a9 Rename run_command2() to run_command()
+ a74443f sandbox: Rename run_command() to builtin_run_command()
+
+The first patch is some test things that enable your code to be compiled,
+but that you don't want to submit because there is an existing patch for it
+on the list. So you can tell patman to create and check some patches
+(skipping the first patch) with:
+
+ patman -s1 -n
+
+If you want to do all of them including the work-in-progress one, then
+(if you are tracking an upstream branch):
+
+ patman -n
+
+Let's say that patman reports an error in the second patch. Then:
+
+ git rebase -i HEAD~6
+ <change 'pick' to 'edit' in 89234f5>
+ <use editor to make code changes>
+ git add -u
+ git rebase --continue
+
+Now you have an updated patch series. To check it:
+
+ patman -s1 -n
+
+Let's say it is now clean and you want to send it. Now you need to set up
+the destination. So amend the top commit with:
+
+ git commit --amend
+
+Use your editor to add some tags, so that the whole commit message is:
+
+ The current run_command() is really only one of the options, with
+ hush providing the other. It really shouldn't be called directly
+ in case the hush parser is bring used, so rename this function to
+ better explain its purpose.
+
+ Series-to: u-boot
+ Series-cc: bfin, marex
+ Series-prefix: RFC
+ Cover-letter:
+ Unified command execution in one place
+
+ At present two parsers have similar code to execute commands. Also
+ cmd_usage() is called all over the place. This series adds a single
+ function which processes commands called cmd_process().
+ END
+
+ Change-Id: Ica71a14c1f0ecb5650f771a32fecb8d2eb9d8a17
+
+
+You want this to be an RFC and Cc the whole series to the bfin alias and
+to Marek. Two of the patches have tags (those are the bits at the front of
+the subject that say mmc: sparc: and sandbox:), so 8d640a7 will be Cc'd to
+mmc and sparc, and the last one to sandbox.
+
+Now to send the patches, take off the -n flag:
+
+ patman -s1
+
+The patches will be created, shown in your editor, and then sent along with
+the cover letter. Note that patman's tags are automatically removed so that
+people on the list don't see your secret info.
+
+Of course patches often attract comments and you need to make some updates.
+Let's say one person sent comments and you get an Acked-by: on one patch.
+Also, the patch on the list that you were waiting for has been merged,
+so you can drop your wip commit. So you resync with upstream:
+
+ git fetch origin (or whatever upstream is called)
+ git rebase origin/master
+
+and use git rebase -i to edit the commits, dropping the wip one. You add
+the ack tag to one commit:
+
+ Acked-by: Heiko Schocher <hs@denx.de>
+
+update the Series-cc: in the top commit:
+
+ Series-cc: bfin, marex, Heiko Schocher <hs@denx.de>
+
+and remove the Series-prefix: tag since it it isn't an RFC any more. The
+series is now version two, so the series info in the top commit looks like
+this:
+
+ Series-to: u-boot
+ Series-cc: bfin, marex, Heiko Schocher <hs@denx.de>
+ Series-version: 2
+ Cover-letter:
+ ...
+
+Finally, you need to add a change log to the two commits you changed. You
+add change logs to each individual commit where the changes happened, like
+this:
+
+ Series-changes: 2
+ - Updated the command decoder to reduce code size
+ - Wound the torque propounder up a little more
+
+(note the blank line at the end of the list)
+
+When you run patman it will collect all the change logs from the different
+commits and combine them into the cover letter, if you have one. So finally
+you have a new series of commits:
+
+ faeb973 Don't include standard parser if hush is used
+ 1b2f2fe mmc: sparc: Stop using builtin_run_command()
+ cfbe330 Rename run_command2() to run_command()
+ 0682677 sandbox: Rename run_command() to builtin_run_command()
+
+so to send them:
+
+ patman
+
+and it will create and send the version 2 series.
+
+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:
+
+ git tag sent/us-cmd-rfc
+ ...later...
+ git tag sent/us-cmd-v2
+
+4. If you want to modify the patches a little before sending, you can do
+this in your editor, but be careful!
+
+5. If you want to run git send-email yourself, use the -n flag which will
+print out the command line patman would have used.
+
+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.
+
+
+Other thoughts
+==============
+
+This script has been split into sensible files but still needs work.
+Most of these are indicated by a TODO in the code.
+
+It would be nice if this could handle the In-reply-to side of things.
+
+The tests are incomplete, as is customary. Use the -t flag to run them,
+and make sure you are in the tools/scripts/patman directory first:
+
+ $ cd /path/to/u-boot
+ $ cd tools/scripts/patman
+ $ patman -t
+
+Error handling doesn't always produce friendly error messages - e.g.
+putting an incorrect tag in a commit may provide a confusing message.
+
+There might be a few other features not mentioned in this README. They
+might be bugs. In particular, tags are case sensitive which is probably
+a bad thing.

+Subject: [PATCH 1/4] Add microsecond boot time measurement
+
+This defines the basics of a new boot time measurement feature. This allows
+logging of very accurate time measurements as the boot proceeds, by using
+an available microsecond counter.
