+What is this?
+=============
+
+This tool handles building U-Boot to check that you have not broken it
+with your patch series. It can build each individual commit and report
+which boards fail on which commits, and which errors come up. It aims
+to make full use of multi-processor machines.
+
+A key feature of buildman is its output summary, which allows warnings,
+errors or image size increases in a particular commit or board to be
+quickly identified and the offending commit pinpointed. This can be a big
+help for anyone working with >10 patches at a time.
+
+
+Caveats
+=======
+
+Buildman is still in its infancy. It is already a very useful tool, but
+expect to find problems and send patches.
+
+Buildman can be stopped and restarted, in which case it will continue
+where it left off. This should happen cleanly and without side-effects.
+If not, it is a bug, for which a patch would be welcome.
+
+Buildman gets so tied up in its work that it can ignore the outside world.
+You may need to press Ctrl-C several times to quit it. Also it will print
+out various exceptions when stopped.
+
+
+Theory of Operation
+===================
+
+(please read this section in full twice or you will be perpetually confused)
+
+Buildman is a builder. It is not make, although it runs make. It does not
+produce any useful output on the terminal while building, except for
+progress information. All the output (errors, warnings and binaries if you
+are ask for them) is stored in output directories, which you can look at
+while the build is progressing, or when it is finished.
+
+Buildman produces a concise summary of which boards succeeded and failed.
+It shows which commit introduced which board failure using a simple
+red/green colour coding. Full error information can be requested, in which
+case it is de-duped and displayed against the commit that introduced the
+error. An example workflow is below.
+
+Buildman stores image size information and can report changes in image size
+from commit to commit. An example of this is below.
+
+Buildman starts multiple threads, and each thread builds for one board at
+a time. A thread starts at the first commit, configures the source for your
+board and builds it. Then it checks out the next commit and does an
+incremental build. Eventually the thread reaches the last commit and stops.
+If errors or warnings are found along the way, the thread will reconfigure
+after every commit, and your build will be very slow. This is because a
+file that produces just a warning would not normally be rebuilt in an
+incremental build.
+
+Buildman works in an entirely separate place from your U-Boot repository.
+It creates a separate working directory for each thread, and puts the
+output files in the working directory, organised by commit name and board
+name, in a two-level hierarchy.
+
+Buildman is invoked in your U-Boot directory, the one with the .git
+directory. It clones this repository into a copy for each thread, and the
+threads do not affect the state of your git repository. Any checkouts done
+by the thread affect only the working directory for that thread.
+
+Buildman automatically selects the correct toolchain for each board. You
+must supply suitable toolchains, but buildman takes care of selecting the
+right one.
+
+Buildman always builds a branch, and always builds the upstream commit as
+well, for comparison. It cannot build individual commits at present, unless
+(maybe) you point it at an empty branch. Put all your commits in a branch,
+set the branch's upstream to a valid value, and all will be well. Otherwise
+buildman will perform random actions. Use -n to check what the random
+actions might be.
+
+Buildman is optimised for building many commits at once, for many boards.
+On multi-core machines, Buildman is fast because it uses most of the
+available CPU power. When it gets to the end, or if you are building just
+a few commits or boards, it will be pretty slow. As a tip, if you don't
+plan to use your machine for anything else, you can use -T to increase the
+number of threads beyond the default.
+
+Buildman lets you build all boards, or a subset. Specify the subset using
+the board name, architecture name, SOC name, or anything else in the
+boards.cfg file. So 'at91' will build all AT91 boards (arm), powerpc will
+build all PowerPC boards.
+
+Buildman does not store intermediate object files. It optionally copies
+the binary output into a directory when a build is successful. Size
+information is always recorded. It needs a fair bit of disk space to work,
+typically 250MB per thread.
+
+
+Setting up
+==========
+
+1. Get the U-Boot source. You probably already have it, but if not these
+steps should get you started with a repo and some commits for testing.
+
+$ cd /path/to/u-boot
+$ git clone git://git.denx.de/u-boot.git .
+$ git checkout -b my-branch origin/master
+$ # Add some commits to the branch, reading for testing
+
+2. Create ~/.buildman to tell buildman where to find tool chains. As an
+example:
+
+# Buildman settings file
+
+[toolchain]
+root: /
+rest: /toolchains/*
+eldk: /opt/eldk-4.2
+
+[toolchain-alias]
+x86: i386
+blackfin: bfin
+sh: sh4
+nds32: nds32le
+openrisc: or32
+
+
+This selects the available toolchain paths. Add the base directory for
+each of your toolchains here. Buildman will search inside these directories
+and also in any '/usr' and '/usr/bin' subdirectories.
+
+Make sure the tags (here root: rest: and eldk:) are unique.
+
+The toolchain-alias section indicates that the i386 toolchain should be used
+to build x86 commits.
+
+
+2. Check the available toolchains
+
+Run this check to make sure that you have a toolchain for every architecture.

+
+
+How to run it
+=============
+
+First do a dry run using the -n flag: (replace <branch> with a real, local
+branch with a valid upstream)
+
+$ ./tools/buildman/buildman -b <branch> -n
+
+If it can't detect the upstream branch, try checking out the branch, and
+doing something like 'git branch --set-upstream <branch> upstream/master'
+or something similar.
+
+As an exmmple:
+
+Dry run, so not doing much. But I would do this:
+

+
+Total boards to build for each commit: 1059
+
+This shows that it will build all 1059 boards, using 4 threads (because
+we have a 4-core CPU). Each thread will run with -j1, meaning that each
+make job will use a single CPU. The list of commits to be built helps you
+confirm that things look about right. Notice that buildman has chosen a
+'base' directory for you, immediately above your source tree.
+
+Buildman works entirely inside the base directory, here ../lcd9b,
+creating a working directory for each thread, and creating output
+directories for each commit and board.
+
+
+Suggested Workflow
+==================
+
+To run the build for real, take off the -n:
+
+$ ./tools/buildman/buildman -b <branch>
+
+Buildman will set up some working directories, and get started. After a
+minute or so it will settle down to a steady pace, with a display like this:
+
+Building 18 commits for 1059 boards (4 threads, 1 job per thread)
+ 528 36 124 /19062 1:13:30 : SIMPC8313_SP
+
+This means that it is building 19062 board/commit combinations. So far it
+has managed to succesfully build 528. Another 36 have built with warnings,
+and 124 more didn't build at all. Buildman expects to complete the process
+in an hour and 15 minutes. Use this time to buy a faster computer.
+
+
+To find out how the build went, ask for a summary with -s. You can do this
+either before the build completes (presumably in another terminal) or or
+afterwards. Let's work through an example of how this is used:
+
+$ ./tools/buildman/buildman -b lcd9b -s
+...
+01: Merge branch 'master' of git://git.denx.de/u-boot-arm
+ powerpc: + galaxy5200_LOWBOOT
+02: tegra: Use const for pinmux_config_pingroup/table()
+03: tegra: Add display support to funcmux
+04: tegra: fdt: Add pwm binding and node
+05: tegra: fdt: Add LCD definitions for Tegra
+06: tegra: Add support for PWM
+07: tegra: Add SOC support for display/lcd
+08: tegra: Add LCD driver
+09: tegra: Add LCD support to Nvidia boards
+10: arm: Add control over cachability of memory regions
+11: lcd: Add CONFIG_LCD_ALIGNMENT to select frame buffer alignment
+12: lcd: Add support for flushing LCD fb from dcache after update
+ arm: + lubbock
+13: tegra: Align LCD frame buffer to section boundary
+14: tegra: Support control of cache settings for LCD
+15: tegra: fdt: Add LCD definitions for Seaboard
+16: lcd: Add CONFIG_CONSOLE_SCROLL_LINES option to speed console
+17: tegra: Enable display/lcd support on Seaboard
+18: wip
+
+This shows which commits have succeeded and which have failed. In this case
+the build is still in progress so many boards are not built yet (use -u to
+see which ones). But still we can see a few failures. The galaxy5200_LOWBOOT
+never builds correctly. This could be a problem with our toolchain, or it
+could be a bug in the upstream. The good news is that we probably don't need
+to blame our commits. The bad news is it isn't tested on that board.
+
+Commit 12 broke lubbock. That's what the '+ lubbock' means. The failure
+is never fixed by a later commit, or you would see lubbock again, in green,
+without the +.
+
+To see the actual error:
+
+$ ./tools/buildman/buildman -b <branch> -se lubbock
+...
+12: lcd: Add support for flushing LCD fb from dcache after update
+ arm: + lubbock

+17: tegra: Enable display/lcd support on Seaboard
+18: wip
+
+So the problem is in lcd.c, due to missing cache operations. This information
+should be enough to work out what that commit is doing to break these
+boards. (In this case pxa did not have cache operations defined).
+
+If you see error lines marked with - that means that the errors were fixed
+by that commit. Sometimes commits can be in the wrong order, so that a
+breakage is introduced for a few commits and fixed by later commits. This
+shows up clearly with buildman. You can then reorder the commits and try
+again.
+
+At commit 16, the error moves - you can see that the old error at line 120
+is fixed, but there is a new one at line 126. This is probably only because
+we added some code and moved the broken line futher down the file.
+
+If many boards have the same error, then -e will display the error only
+once. This makes the output as concise as possible.
+
+The full build output in this case is available in:
+
+../lcd9b/12_of_18_gd92aff7_lcd--Add-support-for/lubbock/
+
+ done: Indicates the build was done, and holds the return code from make.
+ This is 0 for a good build, typically 2 for a failure.
+
+ err: Output from stderr, if any. Errors and warnings appear here.
+
+ log: Output from stdout. Normally there isn't any since buildman runs
+ in silent mode for now.
+
+ toolchain: Shows information about the toolchain used for the build.
+
+ sizes: Shows image size information.
+
+It is possible to get the build output there also. Use the -k option for
+this. In that case you will also see some output files, like:
+
+ System.map toolchain u-boot u-boot.bin u-boot.map autoconf.mk
+ (also SPL versions u-boot-spl and u-boot-spl.bin if available)
+
+
+Checking Image Sizes
+====================
+
+A key requirement for U-Boot is that you keep code/data size to a minimum.
+Where a new feature increases this noticeably it should normally be put
+behind a CONFIG flag so that boards can leave it off and keep the image
+size more or less the same with each new release.
+
+To check the impact of your commits on image size, use -S. For example:
+
+$ ./tools/buildman/buildman -b us-x86 -sS
+Summary of 10 commits for 1066 boards (4 threads, 1 job per thread)
+01: MAKEALL: add support for per architecture toolchains
+02: x86: Add function to get top of usable ram
+ x86: (for 1/3 boards) text -272.0 rodata +41.0
+03: x86: Add basic cache operations
+04: x86: Permit bootstage and timer data to be used prior to relocation
+ x86: (for 1/3 boards) data +16.0
+05: x86: Add an __end symbol to signal the end of the U-Boot binary
+ x86: (for 1/3 boards) text +76.0
+06: x86: Rearrange the output input to remove BSS
+ x86: (for 1/3 boards) bss -2140.0
+07: x86: Support relocation of FDT on start-up
+ x86: + coreboot-x86
+08: x86: Add error checking to x86 relocation code
+09: x86: Adjust link device tree include file
+10: x86: Enable CONFIG_OF_CONTROL on coreboot
+
+
+You can see that image size only changed on x86, which is good because this
+series is not supposed to change any other board. From commit 7 onwards the
+build fails so we don't get code size numbers. The numbers are fractional
+because they are an average of all boards for that architecture. The
+intention is to allow you to quickly find image size problems introduced by
+your commits.
+
+Note that the 'text' region and 'rodata' are split out. You should add the
+two together to get the total read-only size (reported as the first column
+in the output from binutil's 'size' utility).
+
+A useful option is --step which lets you skip some commits. For example
+--step 2 will show the image sizes for only every 2nd commit (so it will
+compare the image sizes of the 1st, 3rd, 5th... commits). You can also use
+--step 0 which will compare only the first and last commits. This is useful
+for an overview of how your entire series affects code size.
+
+You can also use -d to see a detailed size breakdown for each board. This
+list is sorted in order from largest growth to largest reduction.
+
+It is possible to go a little further with the -B option (--bloat). This
+shows where U-Boot has bloted, breaking the size change down to the function
+level. Example output is below:
+
+$ ./tools/buildman/buildman -b us-mem4 -sSdB
+...

+
+
+This shows that commit 19 has increased text size for arm (although only one
+board was built) and by 96 bytes for powerpc. This increase was offset in both
+cases by reductions in rodata and data/bss.
+
+Shown below the summary lines is the sizes for each board. Below each board
+is the sizes for each function. This information starts with:
+
+ add - number of functions added / removed
+ grow - number of functions which grew / shrunk
+ bytes - number of bytes of code added to / removed from all functions,
+ plus the total byte change in brackets
+
+The change seems to be that hash_command() has increased by more than the
+do_mem_crc() function has decreased. The function sizes typically add up to
+roughly the text area size, but note that every read-only section except
+rodata is included in 'text', so the function total does not exactly
+correspond.
+
+It is common when refactoring code for the rodata to decrease as the text size
+increases, and vice versa.
+
+
+Other options
+=============
+
+Buildman has various other command line options. Try --help to see them.
+
+
+TODO
+====
+
+This has mostly be written in my spare time as a response to my difficulties
+in testing large series of patches. Apart from tidying up there is quite a
+bit of scope for improvement. Things like better error diffs, easier access
+to log files, error display while building. Also it would be nice it buildman
+could 'hunt' for problems, perhaps by building a few boards for each arch,
+or checking commits for changed files and building only boards which use
+those files.
+
+
+Credits
+=======
+
+Thanks to Grant Grundler <grundler@chromium.org> for his ideas for improving
+the build speed by building all commits for a board instead of the other
+way around.

+Theory of Operation
+
+Please see README for user documentation, and you should be familiar with
+that before trying to make sense of this.
+
+Buildman works by keeping the machine as busy as possible, building different
+commits for different boards on multiple CPUs at once.
+
+The source repo (self.git_dir) contains all the commits to be built. Each
+thread works on a single board at a time. It checks out the first commit,
+configures it for that board, then builds it. Then it checks out the next
+commit and builds it (typically without re-configuring). When it runs out
+of commits, it gets another job from the builder and starts again with that
+board.
+
+Clearly the builder threads could work either way - they could check out a
+commit and then built it for all boards. Using separate directories for each
+commit/board pair they could leave their build product around afterwards
+also.
+
+The intent behind building a single board for multiple commits, is to make
+use of incremental builds. Since each commit is built incrementally from
+the previous one, builds are faster. Reconfiguring for a different board
+removes all intermediate object files.
+
+Many threads can be working at once, but each has its own working directory.
+When a thread finishes a build, it puts the output files into a result
+directory.
+
+The base directory used by buildman is normally '../<branch>', i.e.
+a directory higher than the source repository and named after the branch
+being built.
+
+Within the base directory, we have one subdirectory for each commit. Within
+that is one subdirectory for each board. Within that is the build output for
+that commit/board combination.
+
+Buildman also create working directories for each thread, in a .bm-work/
+subdirectory in the base dir.
+
+As an example, say we are building branch 'us-net' for boards 'sandbox' and
+'seaboard', and say that us-net has two commits. We will have directories
+like this:
+
+us-net/ base directory
+ 01_of_02_g4ed4ebc_net--Add-tftp-speed-/
+ sandbox/
+ u-boot.bin
+ seaboard/
+ u-boot.bin
+ 02_of_02_g4ed4ebc_net--Check-tftp-comp/
+ sandbox/
+ u-boot.bin
+ seaboard/
+ u-boot.bin
+ .bm-work/
+ 00/ working directory for thread 0 (contains source checkout)
+ build/ build output
+ 01/ working directory for thread 1
+ build/ build output
+ ...
+u-boot/ source directory
