-(Please read 'How to change from MAKEALL' if you are used to that tool)
-
-Quick-start
-===========
-
-If you just want to quickly set up buildman so you can build something (for
-example Raspberry Pi 2):
-
- cd /path/to/u-boot
- PATH=$PATH:`pwd`/tools/buildman
- buildman --fetch-arch arm
- buildman -k rpi_2
- ls ../current/rpi_2
- # u-boot.bin is the output image
-
-
-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 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. You may have to kill it since the
-Ctrl-C handling is somewhat broken.
-
-
-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 (but see -v below). All the output (errors, warnings and
-binaries if you ask for them) is stored in output directories, which you can
-look at from a separate 'buildman -s' instance while the build is progressing,
-or when it is finished.
-
-Buildman is designed to build entire git branches, i.e. muliple commits. It
-can be run repeatedly on the same branch after making changes to commits on
-that branch. In this case it will automatically rebuild commits which have
-changed (and remove its old results for that commit). It is possible to build
-a branch for one board, then later build it for another board. This adds to
-the output, so now you have results for two boards. If you want buildman to
-re-build a commit it has already built (e.g. because of a toolchain update),
-use the -f flag.
-
-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 (with yellow/cyan for warnings). 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 (i.e. not using 'make xxx_defconfig' unless you use -C).
-Eventually the thread reaches the last commit and stops. If a commit causes
-an error or warning, buildman will try it again after reconfiguring (but see
--Q). Thus some commits may be built twice, with the first result silently
-discarded. Lots of errors and warnings will causes lots of reconfigures 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. Once a thread finishes
-building all the commits for a board, it starts on the commits for another
-board.
-
-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 (but see -P).
-
-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 tool chain for each board. You
-must supply suitable tool chains (see --fetch-arch), but buildman takes care
-of selecting the right one.
-
-Buildman generally builds a branch (with the -b flag), and in this case
-builds the upstream commit as well, for comparison. So even if you have one
-commit in your branch, two commits will be built. 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 effectively has two modes: without -s it builds, with -s it
-summarises the results of previous (or active) builds.
-
-If you just want to build the current source tree, leave off the -b flag.
-This will display results and errors as they happen. You can still look at
-them later using -se. Note that buildman will assume that the source has
-changed, and will build all specified boards in this case.
-
-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.
-
-
-Selecting which boards to build
-===============================
-
-Buildman lets you build all boards, or a subset. Specify the subset by passing
-command-line arguments that list the desired build target, architecture,
-CPU, board name, vendor, SoC or options. Multiple arguments are allowed. Each
-argument will be interpreted as a regular expression, so behaviour is a superset
-of exact or substring matching. Examples are:
-
-* 'tegra20' All boards with a Tegra20 SoC
-* 'tegra' All boards with any Tegra Soc (Tegra20, Tegra30, Tegra114...)
-* '^tegra[23]0$' All boards with either Tegra20 or Tegra30 SoC
-* 'powerpc' All PowerPC boards
-
-While the default is to OR the terms together, you can also make use of
-the '&' operator to limit the selection:
-
-* 'freescale & arm sandbox' All Freescale boards with ARM architecture,
- plus sandbox
-
-You can also use -x to specifically exclude some boards. For example:
-
- buildman arm -x nvidia,freescale,.*ball$
-
-means to build all arm boards except nvidia, freescale and anything ending
-with 'ball'.
-
-For building specific boards you can use the --boards (or --bo) option, which
-takes a comma-separated list of board target names and be used multiple times
-on the command line:
-
- buildman --boards sandbox,snow --boards
-
-It is convenient to use the -n option to see what will be built based on
-the subset given. Use -v as well to get an actual list of boards.
-
-Buildman does not store intermediate object files. It optionally copies
-the binary output into a directory when a build is successful (-k). 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 (see 'The
-.buildman file' later for details). As an example:
-
-# Buildman settings file
-
-[toolchain]
-root: /
-rest: /toolchains/*
-eldk: /opt/eldk-4.2
-arm: /opt/linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.08_linux
-aarch64: /opt/linaro/gcc-linaro-aarch64-none-elf-4.8-2013.10_linux
-
-[toolchain-alias]
-x86: i386
-blackfin: bfin
-openrisc: or1k
-
-
-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.
-
-Note that you can also specific exactly toolchain prefixes if you like:
-
-[toolchain-prefix]
-arm: /opt/arm-eabi-4.6/bin/arm-eabi-
-
-or even:
-
-[toolchain-prefix]
-arm: /opt/arm-eabi-4.6/bin/arm-eabi-gcc
-
-This tells buildman that you want to use this exact toolchain for the arm
-architecture. This will override any toolchains found by searching using the
-[toolchain] settings.
-
-Since the toolchain prefix is an explicit request, buildman will report an
-error if a toolchain is not found with that prefix. The current PATH will be
-searched, so it is possible to use:
-
-[toolchain-prefix]
-arm: arm-none-eabi-
-
-and buildman will find arm-none-eabi-gcc in /usr/bin if you have it installed.
-
-[toolchain-wrapper]
-wrapper: ccache
-
-This tells buildman to use a compiler wrapper in front of CROSS_COMPILE. In
-this example, ccache. It doesn't affect the toolchain scan. The wrapper is
-added when CROSS_COMPILE environtal variable is set. The name in this
-section is ignored. If more than one line is provided, only the last one
-is taken.
-
-3. Make sure you have the require Python pre-requisites
-
-Buildman uses multiprocessing, Queue, shutil, StringIO, ConfigParser and
-urllib2. These should normally be available, but if you get an error like
-this then you will need to obtain those modules:
-
- ImportError: No module named multiprocessing
-
-
-4. Check the available toolchains
-
-Run this check to make sure that you have a toolchain for every architecture.

-
-5. Install new toolchains if needed
-
-You can download toolchains and update the [toolchain] section of the
-settings file to find them.
-
-To make this easier, buildman can automatically download and install
-toolchains from kernel.org. First list the available architectures:
-
-$ ./tools/buildman/buildman --fetch-arch list

-
-Buildman should now be set up to use your new toolchain.
-
-At the time of writing, U-Boot has these architectures:
-
- arc, arm, blackfin, m68k, microblaze, mips, nios2, openrisc
- powerpc, sandbox, sh, sparc, x86
-
-Of these, only arc is not available at kernel.org..

-
-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-to upstream/master'
-or something similar. Buildman will try to guess a suitable upstream branch
-if it can't find one (you will see a message like" Guessing upstream as ...).
-You can also use the -c option to manually specify the number of commits to
-build.
-
-As an example:
-
-Dry run, so not doing much. But I would do this:
-
-Building 18 commits for 1059 boards (4 threads, 1 job per thread)
-Build directory: ../lcd9b
- 5bb3505 Merge branch 'master' of git://git.denx.de/u-boot-arm
- c18f1b4 tegra: Use const for pinmux_config_pingroup/table()
- 2f043ae tegra: Add display support to funcmux
- e349900 tegra: fdt: Add pwm binding and node
- 424a5f0 tegra: fdt: Add LCD definitions for Tegra
- 0636ccf tegra: Add support for PWM
- a994fe7 tegra: Add SOC support for display/lcd
- fcd7350 tegra: Add LCD driver
- 4d46e9d tegra: Add LCD support to Nvidia boards
- 991bd48 arm: Add control over cachability of memory regions
- 54e8019 lcd: Add CONFIG_LCD_ALIGNMENT to select frame buffer alignment
- d92aff7 lcd: Add support for flushing LCD fb from dcache after update
- dbd0677 tegra: Align LCD frame buffer to section boundary
- 0cff9b8 tegra: Support control of cache settings for LCD
- 9c56900 tegra: fdt: Add LCD definitions for Seaboard
- 5cc29db lcd: Add CONFIG_CONSOLE_SCROLL_LINES option to speed console
- cac5a23 tegra: Enable display/lcd support on Seaboard
- 49ff541 wip
-
-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 -18374 1:13:30 : SIMPC8313_SP
-
-This means that it is building 19062 board/commit combinations. So far it
-has managed to successfully build 528. Another 36 have built with warnings,
-and 124 more didn't build at all. It has 18374 builds left to complete.
-Buildman expects to complete the process in around an hour and a quarter.
-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
-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

-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 already 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 that our commits are not tested on that
-board.

-Commit 12 broke lubbock. That's what the '+ lubbock', in red, 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:
-

-
-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

-
-Note that if there were other boards with errors, the above command would
-show their errors also. Each line is shown only once. So if lubbock and snow
-produce the same error, we just see:
-
-12: lcd: Add support for flushing LCD fb from dcache after update

-+make: *** [build/u-boot] Error 139
-
-But if you did want to see just the errors for lubbock, use:
-
-$ ./tools/buildman/buildman -b <branch> -se lubbock
-
-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 further down the file.
-
-As mentioned, if many boards have the same error, then -e will display the
-error only once. This makes the output as concise as possible. To see which
-boards have each error, use -l. So it is safe to omit the board name - you
-will not get lots of repeated output for every board.
-
-Buildman tries to distinguish warnings from errors, and shows warning lines
-separately with a 'w' prefix. Warnings introduced show as yellow. Warnings
-fixed show as cyan.
-
-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. Use -V to force a verbose build (this passes V=1
- to 'make')
-
- toolchain: Shows information about the toolchain used for the build.
-
- sizes: Shows image size information.
-
-It is possible to get the build binary 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 disabled 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. It will build
-only the upstream commit and your final branch commit.
-
-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 even possible to go a little further with the -B option (--bloat). This
-shows where U-Boot has bloated, 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 reduced codesize for arm slightly and increased
-it for powerpc. This increase was offset in by reductions in rodata and
-data/bss.
-
-Shown below the summary lines are the sizes for each board. Below each board
-are 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.
-
-
-The .buildman file
-==================
-
-The .buildman file provides information about the available toolchains and
-also allows build flags to be passed to 'make'. It consists of several
-sections, with the section name in square brackets. Within each section are
-a set of (tag, value) pairs.
-
-'[toolchain]' section
-
- This lists the available toolchains. The tag here doesn't matter, but
- make sure it is unique. The value is the path to the toolchain. Buildman
- will look in that path for a file ending in 'gcc'. It will then execute
- it to check that it is a C compiler, passing only the --version flag to
- it. If the return code is 0, buildman assumes that it is a valid C
- compiler. It uses the first part of the name as the architecture and
- strips off the last part when setting the CROSS_COMPILE environment
- variable (parts are delimited with a hyphen).
-
- For example powerpc-linux-gcc will be noted as a toolchain for 'powerpc'
- and CROSS_COMPILE will be set to powerpc-linux- when using it.
-
-'[toolchain-alias]' section
-
- This converts toolchain architecture names to U-Boot names. For example,
- if an x86 toolchains is called i386-linux-gcc it will not normally be
- used for architecture 'x86'. Adding 'x86: i386 x86_64' to this section
- will tell buildman that the i386 and x86_64 toolchains can be used for
- the x86 architecture.
-
-'[make-flags]' section
-
- U-Boot's build system supports a few flags (such as BUILD_TAG) which
- affect the build product. These flags can be specified in the buildman
- settings file. They can also be useful when building U-Boot against other
- open source software.
-
- [make-flags]
- at91-boards=ENABLE_AT91_TEST=1
- snapper9260=${at91-boards} BUILD_TAG=442
- snapper9g45=${at91-boards} BUILD_TAG=443
-
- This will use 'make ENABLE_AT91_TEST=1 BUILD_TAG=442' for snapper9260
- and 'make ENABLE_AT91_TEST=1 BUILD_TAG=443' for snapper9g45. A special
- variable ${target} is available to access the target name (snapper9260
- and snapper9g20 in this case). Variables are resolved recursively. Note
- that variables can only contain the characters A-Z, a-z, 0-9, hyphen (-)
- and underscore (_).
-
- It is expected that any variables added are dealt with in U-Boot's
- config.mk file and documented in the README.
-
- Note that you can pass ad-hoc options to the build using environment
- variables, for example:
-
- SOME_OPTION=1234 ./tools/buildman/buildman my_board
-
-
-Quick Sanity Check
-==================
-
-If you have made changes and want to do a quick sanity check of the
-currently checked-out source, run buildman without the -b flag. This will
-build the selected boards and display build status as it runs (i.e. -v is
-enabled automatically). Use -e to see errors/warnings as well.
-
-
-Building Ranges
-===============
-
-You can build a range of commits by specifying a range instead of a branch
-when using the -b flag. For example:
-
- upstream/master..us-buildman
-
-will build commits in us-buildman that are not in upstream/master.
-
-
-Building Faster
-===============
-
-By default, buildman doesn't execute 'make mrproper' prior to building the
-first commit for each board. This reduces the amount of work 'make' does, and
-hence speeds up the build. To force use of 'make mrproper', use -the -m flag.
-This flag will slow down any buildman invocation, since it increases the amount
-of work done on any build.
-
-One possible application of buildman is as part of a continual edit, build,
-edit, build, ... cycle; repeatedly applying buildman to the same change or
-series of changes while making small incremental modifications to the source
-each time. This provides quick feedback regarding the correctness of recent
-modifications. In this scenario, buildman's default choice of build directory
-causes more build work to be performed than strictly necessary.
-
-By default, each buildman thread uses a single directory for all builds. When a
-thread builds multiple boards, the configuration built in this directory will
-cycle through various different configurations, one per board built by the
-thread. Variations in the configuration will force a rebuild of affected source
-files when a thread switches between boards. Ideally, such buildman-induced
-rebuilds would not happen, thus allowing the build to operate as efficiently as
-the build system and source changes allow. buildman's -P flag may be used to
-enable this; -P causes each board to be built in a separate (board-specific)
-directory, thus avoiding any buildman-induced configuration changes in any
-build directory.
-
-U-Boot's build system embeds information such as a build timestamp into the
-final binary. This information varies each time U-Boot is built. This causes
-various files to be rebuilt even if no source changes are made, which in turn
-requires that the final U-Boot binary be re-linked. This unnecessary work can
-be avoided by turning off the timestamp feature. This can be achieved by
-setting the SOURCE_DATE_EPOCH environment variable to 0.
-
-Combining all of these options together yields the command-line shown below.
-This will provide the quickest possible feedback regarding the current content
-of the source tree, thus allowing rapid tested evolution of the code.
-
- SOURCE_DATE_EPOCH=0 ./tools/buildman/buildman -P tegra
-
-
-Checking configuration
-======================
-
-A common requirement when converting CONFIG options to Kconfig is to check
-that the effective configuration has not changed due to the conversion.
-Buildman supports this with the -K option, used after a build. This shows
-differences in effective configuration between one commit and the next.
-
-For example:
-
- $ buildman -b kc4 -sK
- ...
- 43: Convert CONFIG_SPL_USBETH_SUPPORT to Kconfig
- arm:
- + u-boot.cfg: CONFIG_SPL_ENV_SUPPORT=1 CONFIG_SPL_NET=1
- + u-boot-spl.cfg: CONFIG_SPL_MMC=1 CONFIG_SPL_NAND_SUPPORT=1
- + all: CONFIG_SPL_ENV_SUPPORT=1 CONFIG_SPL_MMC=1 CONFIG_SPL_NAND_SUPPORT=1 CONFIG_SPL_NET=1
- am335x_evm_usbspl :
- + u-boot.cfg: CONFIG_SPL_ENV_SUPPORT=1 CONFIG_SPL_NET=1
- + u-boot-spl.cfg: CONFIG_SPL_MMC=1 CONFIG_SPL_NAND_SUPPORT=1
- + all: CONFIG_SPL_ENV_SUPPORT=1 CONFIG_SPL_MMC=1 CONFIG_SPL_NAND_SUPPORT=1 CONFIG_SPL_NET=1
- 44: Convert CONFIG_SPL_USB_HOST to Kconfig
- ...
-
-This shows that commit 44 enabled three new options for the board
-am335x_evm_usbspl which were not enabled in commit 43. There is also a
-summary for 'arm' showing all the changes detected for that architecture.
-In this case there is only one board with changes, so 'arm' output is the
-same as 'am335x_evm_usbspl'/
-
-The -K option uses the u-boot.cfg, spl/u-boot-spl.cfg and tpl/u-boot-tpl.cfg
-files which are produced by a build. If all you want is to check the
-configuration you can in fact avoid doing a full build, using -D. This tells
-buildman to configuration U-Boot and create the .cfg files, but not actually
-build the source. This is 5-10 times faster than doing a full build.
-
-By default buildman considers the follow two configuration methods
-equivalent:
-
- #define CONFIG_SOME_OPTION
-
- CONFIG_SOME_OPTION=y
-
-The former would appear in a header filer and the latter in a defconfig
-file. The achieve this, buildman considers 'y' to be '1' in configuration
-variables. This avoids lots of useless output when converting a CONFIG
-option to Kconfig. To disable this behaviour, use --squash-config-y.
-
-
-Checking the environment
-========================
-
-When converting CONFIG options which manipulate the default environment,
-a common requirement is to check that the default environment has not
-changed due to the conversion. Buildman supports this with the -U option,
-used after a build. This shows differences in the default environment
-between one commit and the next.
-
-For example:
-
-$ buildman -b squash brppt1 -sU
-Summary of 2 commits for 3 boards (3 threads, 3 jobs per thread)
-01: Migrate bootlimit to Kconfig
-02: Squashed commit of the following:
- c brppt1_mmc: altbootcmd=mmc dev 1; run mmcboot0; -> mmc dev 1; run mmcboot0
- c brppt1_spi: altbootcmd=mmc dev 1; run mmcboot0; -> mmc dev 1; run mmcboot0
- + brppt1_nand: altbootcmd=run usbscript
- - brppt1_nand: altbootcmd=run usbscript
-(no errors to report)
-
-This shows that commit 2 modified the value of 'altbootcmd' for 'brppt1_mmc'
-and 'brppt1_spi', removing a trailing semicolon. 'brppt1_nand' gained an a
-value for 'altbootcmd', but lost one for ' altbootcmd'.
-
-The -U option uses the u-boot.env files which are produced by a build.
-
-
-Building with clang
-===================
-
-To build with clang (sandbox only), use the -O option to override the
-toolchain. For example:
-
- buildman -O clang-7 --board sandbox
-
-
-Doing a simple build
-====================
-
-In some cases you just want to build a single board and get the full output, use
-the -w option, for example:
-
- buildman -o /tmp/build --board sandbox -w
-
-This will write the full build into /tmp/build including object files. You must
-specify the output directory with -o when using -w.
-
-
-Support for IDEs (Integrated Development Environments)
-======================================================
-
-Normally buildman summarises the output and shows information indicating the
-meaning of each line of output. For example a '+' symbol appears at the start of
-each error line. Also, buildman prints information about what it is about to do,
-along with a summary at the end.
-
-When using buildman from an IDE, it is helpful to drop this behaviour. Use the
--I/--ide option for that. You might find -W helpful also so that warnings do
-not cause the build to fail:
-
- buildman -o /tmp/build --board sandbox -wWI
-
-
-Changing the configuration
-==========================
-
-Sometimes it is useful to change the CONFIG options for a build on the fly. This
-can be used to build a board (or multiple) with a few changes to see the impact.
-The -a option supports this:
-
- -a <cfg>
-
-where <cfg> is a CONFIG option (with or without the CONFIG_ prefix) to enable.
-For example:
-
- buildman -a CMD_SETEXPR_FMT
-
-will build with CONFIG_CMD_SETEXPR_FMT enabled.
-
-You can disable options by preceding them with tilde (~). You can specify the
--a option multiple times:
-
- buildman -a CMD_SETEXPR_FMT -a ~CMDLINE
-
-Some options have values, in which case you can change them:
-
- buildman -a 'BOOTCOMMAND="echo hello"' CONFIG_SYS_LOAD_ADDR=0x1000
-
-Note that you must put quotes around string options and the whole thing must be
-in single quotes, to make sure the shell leave it alone.
-
-If you try to set an option that does not exist, or that cannot be changed for
-some other reason (e.g. it is 'selected' by another option), then buildman
-shows an error:
-
- buildman --board sandbox -a FRED
- Building current source for 1 boards (1 thread, 32 jobs per thread)
- 0 0 0 /1 -1 (starting)errs
- Some CONFIG adjustments did not take effect. This may be because
- the request CONFIGs do not exist or conflict with others.
-
- Failed adjustments:
-
- FRED Missing expected line: CONFIG_FRED=y
-
-
-One major caveat with this feature with branches (-b) is that buildman does not
-name the output directories differently when you change the configuration, so
-doing the same build again with different configuration will not trigger a
-rebuild. You can use -f to work around that.
-
-
-Other options
-=============
-
-Buildman has various other command-line options. Try --help to see them.
-
-To find out what toolchain prefix buildman will use for a build, use the -A
-option.
-
-To request that compiler warnings be promoted to errors, use -E. This passes the
--Werror flag to the compiler. Note that the build can still produce warnings
-with -E, e.g. the migration warnings:
-
- ===================== WARNING ======================
- This board does not use CONFIG_DM_MMC. Please update
- ...
- ====================================================
-
-When doing builds, Buildman's return code will reflect the overall result:
-
- 0 (success) No errors or warnings found
- 100 Errors found
- 101 Warnings found (only if no -W)
-
-You can use -W to tell Buildman to return 0 (success) instead of 101 when
-warnings are found. Note that it can be useful to combine -E and -W. This means
-that all compiler warnings will produce failures (code 100) and all other
-warnings will produce success (since 101 is changed to 0).
-
-If there are both warnings and errors, errors win, so buildman returns 100.
-
-The -y option is provided (for use with -s) to ignore the bountiful device-tree
-warnings. Similarly, -Y tells buildman to ignore the migration warnings.
-
-Sometimes you might get an error in a thread that is not handled by buildman,
-perhaps due to a failure of a tool that it calls. You might see the output, but
-then buildman hangs. Failing to handle any eventuality is a bug in buildman and
-should be reported. But you can use -T0 to disable threading and hopefully
-figure out the root cause of the build failure.
-
-Build summary
-=============
-
-When buildman finishes it shows a summary, something like this:
-
- Completed: 5 total built, duration 0:00:21, rate 0.24
-
-This shows that a total of 5 builds were done across all selected boards, it
-took 21 seconds and the builds happened at the rate of 0.24 per second. The
-latter number depends on the speed of your machine and the efficiency of the
-U-Boot build.
-
-
-How to change from MAKEALL
-==========================
-
-Buildman includes most of the features of MAKEALL and is generally faster
-and easier to use. In particular it builds entire branches: if a particular
-commit introduces an error in a particular board, buildman can easily show
-you this, even if a later commit fixes that error.
-
-The reasons to deprecate MAKEALL are:
-- We don't want to maintain two build systems
-- Buildman is typically faster
-- Buildman has a lot more features
-
-But still, many people will be sad to lose MAKEALL. If you are used to
-MAKEALL, here are a few pointers.
-
-First you need to set up your tool chains - see the 'Setting up' section
-for details. Once you have your required toolchain(s) detected then you are
-ready to go.
-
-To build the current source tree, run buildman without a -b flag:
-
- ./tools/buildman/buildman <list of things to build>
-
-This will build the current source tree for the given boards and display
-the results and errors.
-
-However buildman usually works on entire branches, and for that you must
-specify a board flag:
-
- ./tools/buildman/buildman -b <branch_name> <list of things to build>
-
-followed by (afterwards, or perhaps concurrently in another terminal):
-
- ./tools/buildman/buildman -b <branch_name> -s <list of things to build>
-
-to see the results of the build. Rather than showing you all the output,
-buildman just shows a summary, with red indicating that a commit introduced
-an error and green indicating that a commit fixed an error. Use the -e
-flag to see the full errors and -l to see which boards caused which errors.
-
-If you really want to see build results as they happen, use -v when doing a
-build (and -e to see the errors/warnings too).
-
-You don't need to stick around on that branch while buildman is running. It
-checks out its own copy of the source code, so you can change branches,
-add commits, etc. without affecting the build in progress.
-
-The <list of things to build> can include board names, architectures or the
-like. There are no flags to disambiguate since ambiguities are rare. Using
-the examples from MAKEALL:
-
-Examples:
- - build all Power Architecture boards:
- MAKEALL -a powerpc
- MAKEALL --arch powerpc
- MAKEALL powerpc
- ** buildman -b <branch> powerpc
- - build all PowerPC boards manufactured by vendor "esd":
- MAKEALL -a powerpc -v esd
- ** buildman -b <branch> esd
- - build all PowerPC boards manufactured either by "keymile" or "siemens":
- MAKEALL -a powerpc -v keymile -v siemens
- ** buildman -b <branch> keymile siemens
- - build all Freescale boards with MPC83xx CPUs, plus all 4xx boards:
- MAKEALL -c mpc83xx -v freescale 4xx
- ** buildman -b <branch> mpc83xx freescale 4xx
-
-Buildman automatically tries to use all the CPUs in your machine. If you
-are building a lot of boards it will use one thread for every CPU core
-it detects in your machine. This is like MAKEALL's BUILD_NBUILDS option.
-You can use the -T flag to change the number of threads. If you are only
-building a few boards, buildman will automatically run make with the -j
-flag to increase the number of concurrent make tasks. It isn't normally
-that helpful to fiddle with this option, but if you use the BUILD_NCPUS
-option in MAKEALL then -j is the equivalent in buildman.
-
-Buildman puts its output in ../<branch_name> by default but you can change
-this with the -o option. Buildman normally does out-of-tree builds: use -i
-to disable that if you really want to. But be careful that once you have
-used -i you pollute buildman's copies of the source tree, and you will need
-to remove the build directory (normally ../<branch_name>) to run buildman
-in normal mode (without -i).
-
-Buildman doesn't keep the output result normally, but use the -k option to
-do this.
-
-Please read 'Theory of Operation' a few times as it will make a lot of
-things clearer.
-
-Some options you might like are:
-
- -B shows which functions are growing/shrinking in which commit - great
- for finding code bloat.
- -S shows image sizes for each commit (just an overall summary)
- -u shows boards that you haven't built yet
- --step 0 will build just the upstream commit and the last commit of your
- branch. This is often a quick sanity check that your branch doesn't
- break anything. But note this does not check bisectability!
-
-
-Using boards.cfg
-================
-
-This file is no-longer needed by buildman but it is still generated in the
-working directory. This helps avoid a delay on every build, since scanning all
-the Kconfig files takes a few seconds. Use the -R flag to force regeneration
-of the file - in that case buildman exits after writing the file. with exit code
-2 if there was an error in the maintainer files.
-
-You should use 'buildman -nv <criteria>' instead of greoing the boards.cfg file,
-since it may be dropped altogether in future.
-
-
-TODO
-====
-
-Many improvements have been made over the years. There is still quite a bit of
-scope for more though, e.g.:
-
-- easier access to log files
-- 'hunting' 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.

+Buildman build tool
+===================
+
+Quick-start
+-----------
+
+If you just want to quickly set up buildman so you can build something (for
+example Raspberry Pi 2):
+
+.. code-block:: bash
+
+ cd /path/to/u-boot
+ PATH=$PATH:`pwd`/tools/buildman
+ buildman --fetch-arch arm
+ buildman -k rpi_2
+ ls ../current/rpi_2
+ # u-boot.bin is the output image
+
+
+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 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. You may have to kill it since the
+Ctrl-C handling is somewhat broken.
+
+
+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 (but see -v below). All the output (errors, warnings and
+binaries if you ask for them) is stored in output directories, which you can
+look at from a separate 'buildman -s' instance while the build is progressing,
+or when it is finished.
+
+Buildman is designed to build entire git branches, i.e. muliple commits. It
+can be run repeatedly on the same branch after making changes to commits on
+that branch. In this case it will automatically rebuild commits which have
+changed (and remove its old results for that commit). It is possible to build
+a branch for one board, then later build it for another board. This adds to
+the output, so now you have results for two boards. If you want buildman to
+re-build a commit it has already built (e.g. because of a toolchain update),
+use the -f flag.
+
+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 (with yellow/cyan for warnings). 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 (i.e. not using 'make xxx_defconfig' unless you use -C).
+Eventually the thread reaches the last commit and stops. If a commit causes
+an error or warning, buildman will try it again after reconfiguring (but see
+-Q). Thus some commits may be built twice, with the first result silently
+discarded. Lots of errors and warnings will causes lots of reconfigures 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. Once a thread finishes
+building all the commits for a board, it starts on the commits for another
+board.
+
+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 (but see -P).
+
+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 tool chain for each board. You
+must supply suitable tool chains (see --fetch-arch), but buildman takes care
+of selecting the right one.
+
+Buildman generally builds a branch (with the -b flag), and in this case
+builds the upstream commit as well, for comparison. So even if you have one
+commit in your branch, two commits will be built. 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 effectively has two modes: without -s it builds, with -s it
+summarises the results of previous (or active) builds.
+
+If you just want to build the current source tree, leave off the -b flag.
+This will display results and errors as they happen. You can still look at
+them later using -se. Note that buildman will assume that the source has
+changed, and will build all specified boards in this case.
+
+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.
+
+
+Selecting which boards to build
+-------------------------------
+
+Buildman lets you build all boards, or a subset. Specify the subset by passing
+command-line arguments that list the desired build target, architecture,
+CPU, board name, vendor, SoC or options. Multiple arguments are allowed. Each
+argument will be interpreted as a regular expression, so behaviour is a superset
+of exact or substring matching. Examples are:
+
+- 'tegra20' - all boards with a Tegra20 SoC
+- 'tegra' - all boards with any Tegra Soc (Tegra20, Tegra30, Tegra114...)
+- '^tegra[23]0$' - all boards with either Tegra20 or Tegra30 SoC
+- 'powerpc' - all PowerPC boards
+
+While the default is to OR the terms together, you can also make use of
+the '&' operator to limit the selection:
+
+- 'freescale & arm sandbox' - all Freescale boards with ARM architecture, plus
+ sandbox
+
+You can also use -x to specifically exclude some boards. For example:
+
+ buildman arm -x nvidia,freescale,.*ball$
+
+means to build all arm boards except nvidia, freescale and anything ending
+with 'ball'.
+
+For building specific boards you can use the --boards (or --bo) option, which
+takes a comma-separated list of board target names and be used multiple times
+on the command line:
+
+.. code-block:: bash
+
+ buildman --boards sandbox,snow --boards
+
+It is convenient to use the -n option to see what will be built based on
+the subset given. Use -v as well to get an actual list of boards.
+
+Buildman does not store intermediate object files. It optionally copies
+the binary output into a directory when a build is successful (-k). Size
+information is always recorded. It needs a fair bit of disk space to work,
+typically 250MB per thread.
+
+
+Setting up
+----------
+
+#. 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.
+
+ .. code-block:: bash
+
+ 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
+
+#. Create ~/.buildman to tell buildman where to find tool chains (see
+ buildman_settings_ for details). As an example::
+
+ # Buildman settings file
+
+ [toolchain]
+ root: /
+ rest: /toolchains/*
+ eldk: /opt/eldk-4.2
+ arm: /opt/linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.08_linux
+ aarch64: /opt/linaro/gcc-linaro-aarch64-none-elf-4.8-2013.10_linux
+
+ [toolchain-prefix]
+ arc = /opt/arc/arc_gnu_2021.03_prebuilt_elf32_le_linux_install/bin/arc-elf32-
+
+ [toolchain-alias]
+ riscv = riscv32
+ sh = sh4
+ x86: i386
+
+
+ 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.
+
+ Note that you can also specific exactly toolchain prefixes if you like::
+
+ [toolchain-prefix]
+ arm: /opt/arm-eabi-4.6/bin/arm-eabi-
+
+ or even::
+
+ [toolchain-prefix]
+ arm: /opt/arm-eabi-4.6/bin/arm-eabi-gcc
+
+ This tells buildman that you want to use this exact toolchain for the arm
+ architecture. This will override any toolchains found by searching using the
+ [toolchain] settings.
+
+ Since the toolchain prefix is an explicit request, buildman will report an
+ error if a toolchain is not found with that prefix. The current PATH will be
+ searched, so it is possible to use::
+
+ [toolchain-prefix]
+ arm: arm-none-eabi-
+
+ and buildman will find arm-none-eabi-gcc in /usr/bin if you have it
+ installed.
+
+ Another example::
+
+ [toolchain-wrapper]
+ wrapper: ccache
+
+ This tells buildman to use a compiler wrapper in front of CROSS_COMPILE. In
+ this example, ccache. It doesn't affect the toolchain scan. The wrapper is
+ added when CROSS_COMPILE environtal variable is set. The name in this
+ section is ignored. If more than one line is provided, only the last one
+ is taken.
+
+#. Make sure you have the require Python pre-requisites
+
+ Buildman uses multiprocessing, Queue, shutil, StringIO, ConfigParser and
+ urllib2. These should normally be available, but if you get an error like
+ this then you will need to obtain those modules::
+
+ ImportError: No module named multiprocessing
+
+
+#. Check the available toolchains
+
+ Run this check to make sure that you have a toolchain for every architecture::

+ You can see that everything is covered, even some strange ones that won't

+
+ To make this easier, buildman can automatically download and install
+ toolchains from kernel.org. First list the available architectures::

+ At the time of writing, U-Boot has these architectures:

+ arc, arm, m68k, microblaze, mips, nios2, powerpc, sandbox, sh, x86, xtensa
+
+
+How to run it
+-------------
+
+First do a dry run using the -n flag: (replace <branch> with a real, local
+branch with a valid upstream):
+
+.. code-block:: bash
+
+ ./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-to upstream/master'
+or something similar. Buildman will try to guess a suitable upstream branch
+if it can't find one (you will see a message like "Guessing upstream as ...").
+You can also use the -c option to manually specify the number of commits to
+build.
+
+As an example::
+
+ Dry run, so not doing much. But I would do this:
+
+ Building 18 commits for 1059 boards (4 threads, 1 job per thread)
+ Build directory: ../lcd9b
+ 5bb3505 Merge branch 'master' of git://git.denx.de/u-boot-arm

+ cac5a23 tegra: Enable display/lcd support on Seaboard
+ 49ff541 wip
+
+ 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:
+
+.. code-block:: bash
+
+ ./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 -18374 1:13:30 : SIMPC8313_SP
+
+This means that it is building 19062 board/commit combinations. So far it
+has managed to successfully build 528. Another 36 have built with warnings,
+and 124 more didn't build at all. It has 18374 builds left to complete.
+Buildman expects to complete the process in around an hour and a quarter.
+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
+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 already 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 that our commits are not tested on that
+board.
+
+Commit 12 broke lubbock. That's what the '+ lubbock', in red, 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
+ ...
+ 12: lcd: Add support for flushing LCD fb from dcache after update
+ arm: + lubbock
+ +common/libcommon.o: In function `lcd_sync':
+ +common/lcd.c:120: undefined reference to `flush_dcache_range'
+ +arm-none-linux-gnueabi-ld: BFD (Sourcery G++ Lite 2010q1-202) 2.19.51.20090709 assertion fail /scratch/julian/2010q1-release-linux-lite/obj/binutils-src-2010q1-202-arm-none-linux-gnueabi-i686-pc-linux-gnu/bfd/elf32-arm.c:12572
+ +make: *** [build/u-boot] Error 139
+ 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
+ -common/lcd.c:120: undefined reference to `flush_dcache_range'
+ +common/lcd.c:125: undefined reference to `flush_dcache_range'
+ 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).
+
+Note that if there were other boards with errors, the above command would
+show their errors also. Each line is shown only once. So if lubbock and snow
+produce the same error, we just see::
+
+ 12: lcd: Add support for flushing LCD fb from dcache after update
+ arm: + lubbock snow
+ +common/libcommon.o: In function `lcd_sync':
+ +common/lcd.c:120: undefined reference to `flush_dcache_range'
+ +arm-none-linux-gnueabi-ld: BFD (Sourcery G++ Lite 2010q1-202) 2.19.51.20090709 assertion fail /scratch/julian/2010q1-release-linux-lite/obj/binutils-src-2010q1-202-arm-none-linux-gnueabi-i686-pc-linux-gnu/bfd/elf32-arm.c:12572
+ +make: *** [build/u-boot] Error 139
+
+But if you did want to see just the errors for lubbock, use:
+
+.. code-block:: bash
+
+ ./tools/buildman/buildman -b <branch> -se lubbock
+
+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 further down the file.
+
+As mentioned, if many boards have the same error, then -e will display the
+error only once. This makes the output as concise as possible. To see which
+boards have each error, use -l. So it is safe to omit the board name - you
+will not get lots of repeated output for every board.
+
+Buildman tries to distinguish warnings from errors, and shows warning lines
+separately with a 'w' prefix. Warnings introduced show as yellow. Warnings
+fixed show as cyan.
+
+The full build output in this case is available in::
+
+ ../lcd9b/12_of_18_gd92aff7_lcd--Add-support-for/lubbock/
+
+Files:
+
+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. Use -V to force a verbose build (this passes V=1 to 'make')
+
+toolchain
+ Shows information about the toolchain used for the build.
+
+sizes
+ Shows image size information.
+
+It is possible to get the build binary 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
+- SPL/TPL versions like 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 disabled 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

+
+
+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. It will build
+only the upstream commit and your final branch commit.
+
+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 even possible to go a little further with the -B option (--bloat). This
+shows where U-Boot has bloated, 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 reduced codesize for arm slightly and increased
+it for powerpc. This increase was offset in by reductions in rodata and
+data/bss.
+
+Shown below the summary lines are the sizes for each board. Below each board
+are 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.
+
+
+.. _buildman_settings:
+
+The .buildman settings file
+---------------------------
+
+The .buildman file provides information about the available toolchains and
+also allows build flags to be passed to 'make'. It consists of several
+sections, with the section name in square brackets. Within each section are
+a set of (tag, value) pairs.
+
+'[global]' section
+ allow-missing
+ Indicates the policy to use for missing blobs. Note that the flags
+ ``--allow-missing`` (``-M``) and ``--no-allow-missing`` (``--no-a``)
+ override these setting.
+
+ always
+ Run with ``-M`` by default.
+
+ multiple
+ Run with ``-M`` if more than one board is being built.
+
+ branch
+ Run with ``-M`` if a branch is being built.
+
+ Note that the last two can be given together::
+
+ allow-missing = multiple branch
+
+'[toolchain]' section
+ This lists the available toolchains. The tag here doesn't matter, but
+ make sure it is unique. The value is the path to the toolchain. Buildman
+ will look in that path for a file ending in 'gcc'. It will then execute
+ it to check that it is a C compiler, passing only the --version flag to
+ it. If the return code is 0, buildman assumes that it is a valid C
+ compiler. It uses the first part of the name as the architecture and
+ strips off the last part when setting the CROSS_COMPILE environment
+ variable (parts are delimited with a hyphen).
+
+ For example powerpc-linux-gcc will be noted as a toolchain for 'powerpc'
+ and CROSS_COMPILE will be set to powerpc-linux- when using it.
+
+'[toolchain-alias]' section
+ This converts toolchain architecture names to U-Boot names. For example,
+ if an x86 toolchains is called i386-linux-gcc it will not normally be
+ used for architecture 'x86'. Adding 'x86: i386 x86_64' to this section
+ will tell buildman that the i386 and x86_64 toolchains can be used for
+ the x86 architecture.
+
+'[make-flags]' section
+ U-Boot's build system supports a few flags (such as BUILD_TAG) which
+ affect the build product. These flags can be specified in the buildman
+ settings file. They can also be useful when building U-Boot against other
+ open source software.
+
+ [make-flags]
+ at91-boards=ENABLE_AT91_TEST=1
+ snapper9260=${at91-boards} BUILD_TAG=442
+ snapper9g45=${at91-boards} BUILD_TAG=443
+
+ This will use 'make ENABLE_AT91_TEST=1 BUILD_TAG=442' for snapper9260
+ and 'make ENABLE_AT91_TEST=1 BUILD_TAG=443' for snapper9g45. A special
+ variable ${target} is available to access the target name (snapper9260
+ and snapper9g20 in this case). Variables are resolved recursively. Note
+ that variables can only contain the characters A-Z, a-z, 0-9, hyphen (-)
+ and underscore (_).
+
+ It is expected that any variables added are dealt with in U-Boot's
+ config.mk file and documented in the README.
+
+ Note that you can pass ad-hoc options to the build using environment
+ variables, for example:
+
+ SOME_OPTION=1234 ./tools/buildman/buildman my_board
+
+
+Quick Sanity Check
+------------------
+
+If you have made changes and want to do a quick sanity check of the
+currently checked-out source, run buildman without the -b flag. This will
+build the selected boards and display build status as it runs (i.e. -v is
+enabled automatically). Use -e to see errors/warnings as well.
+
+
+Building Ranges
+---------------
+
+You can build a range of commits by specifying a range instead of a branch
+when using the -b flag. For example::
+
+ buildman -b upstream/master..us-buildman
+
+will build commits in us-buildman that are not in upstream/master.
+
+
+Building Faster
+---------------
+
+By default, buildman doesn't execute 'make mrproper' prior to building the
+first commit for each board. This reduces the amount of work 'make' does, and
+hence speeds up the build. To force use of 'make mrproper', use -the -m flag.
+This flag will slow down any buildman invocation, since it increases the amount
+of work done on any build.
+
+One possible application of buildman is as part of a continual edit, build,
+edit, build, ... cycle; repeatedly applying buildman to the same change or
+series of changes while making small incremental modifications to the source
+each time. This provides quick feedback regarding the correctness of recent
+modifications. In this scenario, buildman's default choice of build directory
+causes more build work to be performed than strictly necessary.
+
+By default, each buildman thread uses a single directory for all builds. When a
+thread builds multiple boards, the configuration built in this directory will
+cycle through various different configurations, one per board built by the
+thread. Variations in the configuration will force a rebuild of affected source
+files when a thread switches between boards. Ideally, such buildman-induced
+rebuilds would not happen, thus allowing the build to operate as efficiently as
+the build system and source changes allow. buildman's -P flag may be used to
+enable this; -P causes each board to be built in a separate (board-specific)
+directory, thus avoiding any buildman-induced configuration changes in any
+build directory.
+
+U-Boot's build system embeds information such as a build timestamp into the
+final binary. This information varies each time U-Boot is built. This causes
+various files to be rebuilt even if no source changes are made, which in turn
+requires that the final U-Boot binary be re-linked. This unnecessary work can
+be avoided by turning off the timestamp feature. This can be achieved by
+setting the SOURCE_DATE_EPOCH environment variable to 0.
+
+Combining all of these options together yields the command-line shown below.
+This will provide the quickest possible feedback regarding the current content
+of the source tree, thus allowing rapid tested evolution of the code::
+
+ SOURCE_DATE_EPOCH=0 ./tools/buildman/buildman -P tegra
+
+
+Checking configuration
+----------------------
+
+A common requirement when converting CONFIG options to Kconfig is to check
+that the effective configuration has not changed due to the conversion.
+Buildman supports this with the -K option, used after a build. This shows
+differences in effective configuration between one commit and the next.
+
+For example::
+
+ $ buildman -b kc4 -sK
+ ...
+ 43: Convert CONFIG_SPL_USBETH_SUPPORT to Kconfig
+ arm:
+ + u-boot.cfg: CONFIG_SPL_ENV_SUPPORT=1 CONFIG_SPL_NET=1
+ + u-boot-spl.cfg: CONFIG_SPL_MMC=1 CONFIG_SPL_NAND_SUPPORT=1
+ + all: CONFIG_SPL_ENV_SUPPORT=1 CONFIG_SPL_MMC=1 CONFIG_SPL_NAND_SUPPORT=1 CONFIG_SPL_NET=1
+ am335x_evm_usbspl :
+ + u-boot.cfg: CONFIG_SPL_ENV_SUPPORT=1 CONFIG_SPL_NET=1
+ + u-boot-spl.cfg: CONFIG_SPL_MMC=1 CONFIG_SPL_NAND_SUPPORT=1
+ + all: CONFIG_SPL_ENV_SUPPORT=1 CONFIG_SPL_MMC=1 CONFIG_SPL_NAND_SUPPORT=1 CONFIG_SPL_NET=1
+ 44: Convert CONFIG_SPL_USB_HOST to Kconfig
+ ...
+
+This shows that commit 44 enabled three new options for the board
+am335x_evm_usbspl which were not enabled in commit 43. There is also a
+summary for 'arm' showing all the changes detected for that architecture.
+In this case there is only one board with changes, so 'arm' output is the
+same as 'am335x_evm_usbspl'/
+
+The -K option uses the u-boot.cfg, spl/u-boot-spl.cfg and tpl/u-boot-tpl.cfg
+files which are produced by a build. If all you want is to check the
+configuration you can in fact avoid doing a full build, using -D. This tells
+buildman to configuration U-Boot and create the .cfg files, but not actually
+build the source. This is 5-10 times faster than doing a full build.
+
+By default buildman considers the follow two configuration methods
+equivalent::
+
+ #define CONFIG_SOME_OPTION
+
+ CONFIG_SOME_OPTION=y
+
+The former would appear in a header filer and the latter in a defconfig
+file. The achieve this, buildman considers 'y' to be '1' in configuration
+variables. This avoids lots of useless output when converting a CONFIG
+option to Kconfig. To disable this behaviour, use --squash-config-y.
+
+
+Checking the environment
+------------------------
+
+When converting CONFIG options which manipulate the default environment,
+a common requirement is to check that the default environment has not
+changed due to the conversion. Buildman supports this with the -U option,
+used after a build. This shows differences in the default environment
+between one commit and the next.
+
+For example::
+
+ $ buildman -b squash brppt1 -sU
+ Summary of 2 commits for 3 boards (3 threads, 3 jobs per thread)
+ 01: Migrate bootlimit to Kconfig
+ 02: Squashed commit of the following:
+ c brppt1_mmc: altbootcmd=mmc dev 1; run mmcboot0; -> mmc dev 1; run mmcboot0
+ c brppt1_spi: altbootcmd=mmc dev 1; run mmcboot0; -> mmc dev 1; run mmcboot0
+ + brppt1_nand: altbootcmd=run usbscript
+ - brppt1_nand: altbootcmd=run usbscript
+ (no errors to report)
+
+This shows that commit 2 modified the value of 'altbootcmd' for 'brppt1_mmc'
+and 'brppt1_spi', removing a trailing semicolon. 'brppt1_nand' gained an a
+value for 'altbootcmd', but lost one for ' altbootcmd'.
+
+The -U option uses the u-boot.env files which are produced by a build.
+
+
+Building with clang
+-------------------
+
+To build with clang (sandbox only), use the -O option to override the
+toolchain. For example:
+
+.. code-block:: bash
+
+ buildman -O clang-7 --board sandbox
+
+
+Doing a simple build
+--------------------
+
+In some cases you just want to build a single board and get the full output, use
+the -w option, for example:
+
+.. code-block:: bash
+
+ buildman -o /tmp/build --board sandbox -w
+
+This will write the full build into /tmp/build including object files. You must
+specify the output directory with -o when using -w.
+
+
+Support for IDEs (Integrated Development Environments)
+------------------------------------------------------
+
+Normally buildman summarises the output and shows information indicating the
+meaning of each line of output. For example a '+' symbol appears at the start of
+each error line. Also, buildman prints information about what it is about to do,
+along with a summary at the end.
+
+When using buildman from an IDE, it is helpful to drop this behaviour. Use the
+-I/--ide option for that. You might find -W helpful also so that warnings do
+not cause the build to fail:
+
+.. code-block:: bash
+
+ buildman -o /tmp/build --board sandbox -wWI
+
+
+Support for binary blobs
+------------------------
+
+U-Boot is moving to using Binman (see :doc:`../develop/package/binman`) for
+dealing with the complexities of packaging U-Boot along with binary files from
+other projects. These are called 'external blobs' by Binman.
+
+Typically a missing external blob causes a build failure. For build testing of
+a lot of boards, or boards for which you do not have the blobs, you can use the
+-M flag to allow missing blobs. This marks the build as if it succeeded,
+although with warnings shown, including 'Some images are invalid'. If any boards
+fail in this way, buildman exits with status 101.
+
+To convert warnings to errors, use -E. To make buildman return success with
+these warnings, use -W.
+
+It is generally safe to default to enabling -M for all runs of buildman, so long
+as you check the exit code. To do this, add::
+
+ allow-missing = "always"
+
+to the top of the buildman_settings_ file.
+
+
+Changing the configuration
+--------------------------
+
+Sometimes it is useful to change the CONFIG options for a build on the fly. This
+can be used to build a board (or multiple) with a few changes to see the impact.
+The -a option supports this:
+
+.. code-block:: bash
+
+ -a <cfg>
+
+where <cfg> is a CONFIG option (with or without the `CONFIG_` prefix) to enable.
+For example:
+
+.. code-block:: bash
+
+ buildman -a CMD_SETEXPR_FMT
+
+will build with CONFIG_CMD_SETEXPR_FMT enabled.
+
+You can disable options by preceding them with tilde (~). You can specify the
+-a option multiple times:
+
+.. code-block:: bash
+
+ buildman -a CMD_SETEXPR_FMT -a ~CMDLINE
+
+Some options have values, in which case you can change them:
+
+.. code-block:: bash
+
+ buildman -a 'BOOTCOMMAND="echo hello"' CONFIG_SYS_LOAD_ADDR=0x1000
+
+Note that you must put quotes around string options and the whole thing must be
+in single quotes, to make sure the shell leave it alone.
+
+If you try to set an option that does not exist, or that cannot be changed for
+some other reason (e.g. it is 'selected' by another option), then buildman
+shows an error::
+
+ $ buildman --board sandbox -a FRED
+ Building current source for 1 boards (1 thread, 32 jobs per thread)
+ 0 0 0 /1 -1 (starting)errs
+ Some CONFIG adjustments did not take effect. This may be because
+ the request CONFIGs do not exist or conflict with others.
+
+ Failed adjustments:
+
+ FRED Missing expected line: CONFIG_FRED=y
+
+
+One major caveat with this feature with branches (-b) is that buildman does not
+name the output directories differently when you change the configuration, so
+doing the same build again with different configuration will not trigger a
+rebuild. You can use -f to work around that.
+
+
+Other options
+-------------
+
+Buildman has various other command-line options. Try --help to see them.
+
+To find out what toolchain prefix buildman will use for a build, use the -A
+option.
+
+To request that compiler warnings be promoted to errors, use -E. This passes the
+-Werror flag to the compiler. Note that the build can still produce warnings
+with -E, e.g. the migration warnings::
+
+ ===================== WARNING ======================
+ This board does not use CONFIG_DM_MMC. Please update
+ ...
+ ====================================================
+
+When doing builds, Buildman's return code will reflect the overall result::
+
+ 0 (success) No errors or warnings found
+ 100 Errors found
+ 101 Warnings found (only if no -W)
+
+You can use -W to tell Buildman to return 0 (success) instead of 101 when
+warnings are found. Note that it can be useful to combine -E and -W. This means
+that all compiler warnings will produce failures (code 100) and all other
+warnings will produce success (since 101 is changed to 0).
+
+If there are both warnings and errors, errors win, so buildman returns 100.
+
+The -y option is provided (for use with -s) to ignore the bountiful device-tree
+warnings. Similarly, -Y tells buildman to ignore the migration warnings.
+
+Sometimes you might get an error in a thread that is not handled by buildman,
+perhaps due to a failure of a tool that it calls. You might see the output, but
+then buildman hangs. Failing to handle any eventuality is a bug in buildman and
+should be reported. But you can use -T0 to disable threading and hopefully
+figure out the root cause of the build failure.
+
+Build summary
+-------------
+
+When buildman finishes it shows a summary, something like this::
+
+ Completed: 5 total built, duration 0:00:21, rate 0.24
+
+This shows that a total of 5 builds were done across all selected boards, it
+took 21 seconds and the builds happened at the rate of 0.24 per second. The
+latter number depends on the speed of your machine and the efficiency of the
+U-Boot build.
+
+
+Using boards.cfg
+----------------
+
+This file is no-longer needed by buildman but it is still generated in the
+working directory. This helps avoid a delay on every build, since scanning all
+the Kconfig files takes a few seconds. Use the -R flag to force regeneration
+of the file - in that case buildman exits after writing the file. with exit code
+2 if there was an error in the maintainer files.
+
+You should use 'buildman -nv <criteria>' instead of greoing the boards.cfg file,
+since it may be dropped altogether in future.
+
+
+TODO
+----
+
+Many improvements have been made over the years. There is still quite a bit of
+scope for more though, e.g.:
+
+- easier access to log files
+- 'hunting' 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
