To: u-boot
We switched to Kbuild style makefiles at v2014.01-rc1 release.
With that modification, we can write makefiles simpler.
But it is NOT real Kbuild.
As the next step, this series imports (+ adjusts) build scripts
from Linux Kernel under scripts/ directory.
By applying this series, we can get more advantages:
- short log
- perfect dependency tracking
- preparation to the next step: Kconfig
- other things...
Kbuild without Kconfig
----------------------
At first, to make things clearer, let me explain
the difference between "Kbuild" and "Kconfig".
They are, I think, sometimes confusing.
Kbuild - build system used for Linux Kernel.
Some features of Kbuild are:
(a) We can describe makefiles simple.
Just addi objects to "obj-y" like this:
obj-$(CONFIG_FOO) += foo.o
(b) We can describe directory descending nicely
Add a directory name to "obj-y" like this:
obj-$(CONFIG_BAR) += bar/
(c) Short log like follows:
CC common/foo.o
CC common/bar.o
LD common/built-in.o
(d) Perfect dependency tracking
I think this is the biggest advantage.
To be honest, the dependency tracing of U-Boot build system
was not reliable.
Kconfig - A tool to manage CONFIG macros.
We can handle the dependency among CONFIG macros.
Kconfig allows us to modify CONFIG settings easily
by "make config".
GUI interface are also available by "make menuconfig"
All defined CONFIG macros are stored into ".config" file
I think most of you are already familiar with above.
I definitely want to port both of these, but I want to do one by one: Kbuild first.
(If we do Kbuild and Kconfig at the same time, it might be messed up.)
So, I want to do "Kbuild without Kconfig" in this series.
The conventional tool (mkconfig + boards.cfg file)
is used for board configuration.
How to apply this series ?
--------------------------
Before importing new features, I wanted to clean up some parts of makefiles.
I posted many trivial patches to refactor makefiles.
This series uses the followings as prerequisites:
[1] blackfin: Do not generate unused header bootrom-asm-offsets.h
http://patchwork.ozlabs.org/patch/295141/
[2] sandbox: Use system headers first for sandbox's os.c in a different way
http://patchwork.ozlabs.org/patch/294233/
[3] .gitignore: ignore spl/ and tpl/ directories except spl/Makefile
http://patchwork.ozlabs.org/patch/294271/
[4] Makefile: delete a make rule of $(LDSCRIPT)
http://patchwork.ozlabs.org/patch/294717/
[5] post: descend only when CONFIG_HAS_POST is defined
http://patchwork.ozlabs.org/patch/294741/
[6] Makefile: Select objects by CONFIG_ rather than $(ARCH) or $(CPU)
http://patchwork.ozlabs.org/patch/294742/
[7] drivers/usb/gadget: select objects by obj-$(CONFIG-...)
http://patchwork.ozlabs.org/patch/294745/
[8] drivers/mtd: descend into sub directories only when it is necessary
http://patchwork.ozlabs.org/patch/294746/
[9] Makefile: Move some scripts imported from Linux
http://patchwork.ozlabs.org/patch/294780/
[10] Makefile: delete unnecessary CPPFLAGS settings
http://patchwork.ozlabs.org/patch/294829/
[11] Makefile: delete unnecessary lines
http://patchwork.ozlabs.org/patch/295052/
[12] Makefile: Do not create empty autoconf.mk on error
http://patchwork.ozlabs.org/patch/295779/
[13] Makefile: use two double-quotations as a pair
http://patchwork.ozlabs.org/patch/296718/
[14] Makefile: correct dependencies of asm-offsets.[hs]
http://patchwork.ozlabs.org/patch/296722/
[15] examples: x86: delete 82559_eeprom
http://patchwork.ozlabs.org/patch/297608/
[16] Makefile, .gitignore: Cleanup non-existing binaries
http://patchwork.ozlabs.org/patch/297609/
[17] spl/Makefile: merge LIBS-y += arch/$(ARCH)/imx-common
http://patchwork.ozlabs.org/patch/299660/
You need to apply above patches beforehand to use this series.
They are simple patches, so I hope they will be reviewed and applied first.
How to Build ?
--------------
We can build the same as before.
Do board configuraton and then run "make".
$ make omap4_panda_config
Configuring for omap4_panda board...
$ make CROSS_COMPILE=arm-linux-gnueabi-
GEN include/autoconf.mk.dep
GEN include/autoconf.mk
CC lib/asm-offsets.s
GEN include/generated/generic-asm-offsets.h
CC arch/arm/cpu/armv7/omap4/asm-offsets.s
GEN include/generated/asm-offsets.h
HOSTCC scripts/basic/fixdep
...
You will find a difference at a glance, short log
If you need detail log message, please add "V=1".
(You can also use "V=2")
Please note we can not use any more
$ make omap4_panda CROSS_COMPILE=arm-linux-gnueabi-
to do board configuration and "make" at the same time.
Instead, we can use Kbuild-ish way for that purpose:
$ make omap4_panda_config all CROSS_COMPILE=arm-linux-gnuabi-
This series keeps the other features:
- Support out-of-tree build
You can use "O=<dir_name>" like this
$ mkdir build_dir
$ make omap4_panda_config all O=build_dir CROSS_COMPILE=arm-linux-gnueabi-
- Works with parallel make option
Add "-j" option for this. Compiling will get faster.
- Of cource, SPL, TPL build are supported
(nand_spl also works. But "nand_spl" is obsolete and we should switch to "spl".
Until when should we continue to maintain nand_spl?)
- Breaks no boards (except some boards which are already broken)
I built all target boards to prove correctness of this series
at least for compile test.
My Next Plan
------------
- Import Kconfig
Use "make config", "make menuconfig", "make defconfig", etc. in U-Boot.
- More refactoring
Some parts of makefiles are still dirty.
I want to refactor more makefiles in follow-up patches.
- Use "obj-m" for standalone program?? Loadable module??
I have not deceided about this yet.

Ignore generated files by Kbuild such as .*.cmd, *.order, etc.
Besides above,
- Ignore *.s files
We do not need to ignore with file name, asm-offsets.s
- Do not ignore *.rej (for quilt)
- Ignore backup files, \#*#

This commit adds scripts/Makefile.host.tmp which will
be used in the next commit to convert makefiles
under tools/ directory to Kbuild style.
Notice this script, scripts/Makefile.host.tmp
is temporary.
When switching over to real Kbuild,
it will be replaced with scripts/Makefile.host of Linux Kernel.

To: u-boot
Before this commit, makefiles under tools/ directory
were implemented with their own way.
This commit refactors them by using "hostprogs-y" variable.
Several C sources have been added to wrap other C sources
to simplify Makefile.
For example, tools/crc32.c includes lib/crc32.c

Some Samsung boards have their own tools under board/samsung/<board>/tools/.
This commit refactor more makefiles with "hostprogs-y".
Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
---
Note1:
Samsung boards have tools under board/samsung/<board>/tools/
and have tools/mkexynosspl.c too.
It is inconsistent, so we should choose the appropriate
directory in which Samsung-specific tools are stored.
Note2:
I marded TODO item in board/samsung/origen/Makefile.
Samsung engineers, I hope you will fix the root cause of the warning.
# omit -O2 option to suppress
# warning: dereferencing type-punned pointer will break strict-aliasing rules

# Fix the root cause in tools/mkorigenspl.c and delete the following work-around

This commit moves suffix rules from config.mk
to scripts/Makefile.build, which will allow us
to switch smoothly to real Kbuild.
Note1:
post/lib_powerpc/fpu/Makefile has
its own rule to compile C sources.
We need to tweak it to keep the same behavior.
Note2:
There are two file2 with the same name:
arch/arm/lib/crt0.S and eamples/api/crt0.S.
To keep the same build behavior,
examples/api/Makefile also has to be treaked.

From: Masahiro Yamada @ 2013-12-11 11:01 UTC (permalink / raw)
To: u-boot
This commit moves some variable definitions from config.mk
to the top Makefile:
- HOSTCC, HOSTCFLAGS, HOSTLDFLAGS
- AS, LD, CC, CPP, etc.
- SHELL (renamed to CONFIG_SHELL)
I'd like to slim down config.mk file
because it is included from all resursive make.
It is redundant to re-define the variables
every time descending into sub directories.
We should rather define them at the top Makefile
and export them.
SHELL has been renamed to CONFIG_SHELL because
Kbuild uses CONFIG_SHELL, not SHELL.
Some build scripts will be imported from Linux Kernel
in the upcoming commits.

This commit adjusts some files to use Kbuild.include.
- Use cc-option defined in Kbuild.include
(Delete cc-option in config.mk)
- Use cc-version defined in
(Delete cc-version in config.mk)
- Move binutils-version and dtc-version to Kbuild.include
by analogy to cc-version
This commit also adds srctree (same as SRCTREE)
to use Kbuild scripts.

Before this commit, most of compiler flags were defined in config.mk.
But it is redundant because config.mk is included from all recursive make.
This commit moves many complier flags to the top Makefile
and export them.
And we use new vaiarables to store them:
KBUILD_CPPFLAGS, KBUILD_CFLAGS, KBUILD_AFLAGS.
This will allow us to switch more smoothly to Kbuild.

To: u-boot
This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

This patch seems a big change at a glance.
But the idea is pretty simple.
The major change in the top Makefile is imported
from Linux Kernel from Linux Kernel.
The rest parts are for adjusting prefixes.
- omit $(obj) prefixes for files which are generated in
the top directory
- change $(obj)foo to $(obj)/foo for files which are generated
under sub directories.
- add $(srctree)/ or $(src)/ prefixes when we need to point
to the source files.
- The environmanet BUILD_DIR has been renamed to KBUILD_OUTPUT.
So, this commit modifies MAKEALL too.
FYI:
Basic structure of the top Makefile is as follows:
ifeq ($(KBUILD_SRC),)
ifeq ("$(origin O)", "command line")
KBUILD_OUTPUT := $(O)
endif
ifneq ($(KBUILD_OUTPUT),)
<< define KBUILD_SRC and change directory and restart make >>
skip-makefile := 1
endif
endif
ifeq ($(skip-makefile),)
<<Main part of Makefile>>
endif

We are going to switch over to Kbuild in upcoming commits.
Each makefile must have non-empty obj- or obj-y
to generate built-in.o on Kbuild.

Some build scripts including scripts/Makefile.build
will be imported from Linux Kernel in the next commit.
We need to adjust them for U-Boot in the following commits.
To make it easier for reviewers to track the modification,
this commit renames scripts/Makefile.build to
scripts/Makefile.build.tmp beforehand.

This commit imports build scripts from Linux Kernel v3.12
as they are.
I know they include some trailing spaces
but I keep intentionally them untouched.

+ * "Optimize" a list of dependencies as spit out by gcc -MD
+ * for the kernel build
+ * ===========================================================================
+ *
+ * Author Kai Germaschewski
+ * Copyright 2002 by Kai Germaschewski <kai.germaschewski@gmx.de>
+ *
+ * This software may be used and distributed according to the terms
+ * of the GNU General Public License, incorporated herein by reference.
+ *
+ *
+ * Introduction:
+ *
+ * gcc produces a very nice and correct list of dependencies which
+ * tells make when to remake a file.
+ *
+ * To use this list as-is however has the drawback that virtually
+ * every file in the kernel includes autoconf.h.
+ *
+ * If the user re-runs make *config, autoconf.h will be
+ * regenerated. make notices that and will rebuild every file which
+ * includes autoconf.h, i.e. basically all files. This is extremely
+ * annoying if the user just changed CONFIG_HIS_DRIVER from n to m.
+ *
+ * So we play the same trick that "mkdep" played before. We replace
+ * the dependency on autoconf.h by a dependency on every config
+ * option which is mentioned in any of the listed prequisites.
+ *
+ * kconfig populates a tree in include/config/ with an empty file
+ * for each config symbol and when the configuration is updated
+ * the files representing changed config options are touched
+ * which then let make pick up the changes and the files that use
+ * the config symbols are rebuilt.
+ *
+ * So if the user changes his CONFIG_HIS_DRIVER option, only the objects
+ * which depend on "include/linux/config/his/driver.h" will be rebuilt,
+ * so most likely only his driver ;-)
+ *
+ * The idea above dates, by the way, back to Michael E Chastain, AFAIK.
+ *
+ * So to get dependencies right, there are two issues:
+ * o if any of the files the compiler read changed, we need to rebuild
+ * o if the command line given to the compile the file changed, we
+ * better rebuild as well.
+ *
+ * The former is handled by using the -MD output, the later by saving
+ * the command line used to compile the old object and comparing it
+ * to the one we would now use.
+ *
+ * Again, also this idea is pretty old and has been discussed on
+ * kbuild-devel a long time ago. I don't have a sensibly working
+ * internet connection right now, so I rather don't mention names
+ * without double checking.
+ *
+ * This code here has been based partially based on mkdep.c, which
+ * says the following about its history:
+ *
+ * Copyright abandoned, Michael Chastain, <mailto:mec@shout.net>.
+ * This is a C version of syncdep.pl by Werner Almesberger.
+ *
+ *
+ * It is invoked as
+ *
+ * fixdep <depfile> <target> <cmdline>
+ *
+ * and will read the dependency file <depfile>
+ *
+ * The transformed dependency snipped is written to stdout.
+ *
+ * It first generates a line
+ *
+ * cmd_<target> = <cmdline>
+ *
+ * and then basically copies the .<target>.d file to stdout, in the
+ * process filtering out the dependency on autoconf.h and adding
+ * dependencies on include/config/my/option.h for every
+ * CONFIG_MY_OPTION encountered in any of the prequisites.
+ *
+ * It will also filter out all the dependencies on *.ver. We need
+ * to make sure that the generated version checksum are globally up
+ * to date before even starting the recursive build, so it's too late
+ * at this point anyway.
+ *
+ * The algorithm to grep for "CONFIG_..." is bit unusual, but should
+ * be fast ;-) We don't even try to really parse the header files, but
+ * merely grep, i.e. if CONFIG_FOO is mentioned in a comment, it will
+ * be picked up as well. It's not a problem with respect to
+ * correctness, since that can only give too many dependencies, thus
+ * we cannot miss a rebuild. Since people tend to not mention totally
+ * unrelated CONFIG_ options all over the place, it's not an
+ * efficiency problem either.
+ *
+ * (Note: it'd be easy to port over the complete mkdep state machine,
+ * but I don't think the added complexity is worth it)
+ */
+/*
+ * Note 2: if somebody writes HELLO_CONFIG_BOOM in a file, it will depend onto
+ * CONFIG_BOOM. This could seem a bug (not too hard to fix), but please do not
+ * fix it! Some UserModeLinux files (look at arch/um/) call CONFIG_BOOM as
+ * UML_CONFIG_BOOM, to avoid conflicts with /usr/include/linux/autoconf.h,
+ * through arch/um/include/uml-config.h; this fixdep "bug" makes sure that
+ * those files will have correct dependencies.

From: Masahiro Yamada @ 2013-12-11 11:01 UTC (permalink / raw)
To: u-boot
Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, there are ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
for that purpose.
Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
---
Please note that we are not allowed to change CFLAGS locally.
See the following snippet from scripts/Makefile.build
# If the save-* variables changed error out
ifeq ($(KBUILD_NOPEDANTIC),)
ifneq ("$(save-cflags)","$(CFLAGS)")
$(error CFLAGS was changed in "$(kbuild-file)". Fix it to use ccflags-y)
endif
endif
If you are not familiar with Kbuild style makefiles,
I recommend you to read the document in Linux Kernel:

We can get Kbuild-ish log style like this:
GEN include/autoconf.mk
GEN include/autoconf.mk.dep
We do not need XECHO any more.

This commit changes the location of include directives
of board configuration files.
The purpose of this change is:
- Slim down $(TOPDIR)/config.mk
- Prevent $(TOPDIR)/Makefile from including the same
configuration file twice
- Do not include include/config.mk multiple times
because ARCH, CPU, BOARD, VENDOR, SOC are exported
Before this commit:
- include/autoconf.mk was included from $(TOPDIR)/Makefile
and $(TOPDIR)/config.mk
(This means $(TOPDIR)/Makefile included include/autoconf.mk twice)
- include/{spl,tpl}-autoconf.mk was included from $(TOPDIR)/config.mk
- include/config.mk was included from $(TOPDIR)/Makefile
and $(TOPDIR)/config.mk
(This means $(TOPDIR)/Makefile included include/config.mk twice)
After this commit:
- include/autoconf.mk is included from $(TOPDIR)/Makefile
and $(TOPDIR)/scripts/Makefile.build
- include/{spl,tpl}-autoconf.mk is included from $(TOPDIR)/spl/Makefile
and $(TOPDIR)/scripts/Makefile.build
- include/config.mk is included from $(TOPDIR)/config.mk and
$(TOPDIR)/spl/Makefile

Before this commit, {spl,tpl}-autoconf.mk was always generated
at the top Makefile even if SPL(TPL) build was not selected.
This commit moves the build rule of {spl,tpl}-autoconf.mk
from the top Makefile to spl/Makefile.
It prevents unnecessary {spl,tpl}-autoconf.mk from being
generated.

Before this commit, "make tidy" did
"make clean" + delete "*.depend*" files.
But, we do not have "*.depend*" files any more,
which means "make tidy" is the same as "make clean".
This commit removes the redandant target "tidy".

This commit changes the top Makefile to handle various targets
nicely.
Make targets are divided into four categories:
- mixed-targets
We can call a configuration target and build targets
at one command line like follows:
$ make <board_name>_config u-boot
They are handled one by one.
- config targets
<board_name>_config
- no-dot-config-targets
Targets we can run without board configuration such as
clean, mrproper, distclean, TAGS, %docs, etc.
- build targets
The other target which need board configuration.

This commit refactors rules of directory descending
and defines u-boot-dirs and u-boot-all-dirs.
(We will need u-boot-all-dirs when using
scripts/Makefile.clean)
Additionally, rename LIBS-y to libs-y.

$(MTD_VERSION) is used in tools/env/Makefile
If you specify a variable at a command line like:
$ make MTD_VERSION=old env
or specify it thru an envrionment variable like:
$ export MTD_VERSION=old
$ make env
it is inherited to the sub-make too.
We do not need to pass it from the top Makefile explicitely.

This commit refactors cleaning targets such as
clean, clobber, mrpropper, distclean
with scripts/Makefile.clean.
By using scripts/Makefile.clean, we can recursively descend
into subdirectories and delete generated files there.
We do not need add a big list of generated files
to the "clean" target.

We can delete ugly stuff like follows:
clean:

By the way, I am keeping "make clobber" for now.
Do we need "make clobber"?
If we like 3-level cleaning targets, clean, mrproper, distclean,
like Linux Kernel, we can squash "clobber" to "clean".

This commit fixed two problems:
[1] We could not do board configuration and "make all"
in one command line.
For example, the following did not work as we expect:
$ make sandbox_config all
Configuring for sandbox board...
make: Nothing to be done for `all'.
[2] mixed-target build did not work with -j option
For example, the following did not work:
$ make -j8 sandbox_config u-boot
Makefile:481: *** "System not configured - see README". Stop.
make: *** [u-boot] Error 2
make: *** Waiting for unfinished jobs....
Configuring for sandbox board...
Going forward, we can do
$ make -j8 sandbox_config all
This is the same as
$ make sandbox_config
$ make -j8

Can you please push a branch somewhere with all of these and kbuild?

Sure.
u-boot/master was updated after posting this series.
(Prerequisite [1] was merged into the mainline.)
I rebased my local branch and push it to my GitHub space.
Please try this:
git clone git://github.com/masahir0y/u-boot-kbuild.git
cd u-boot-kbuild
git checktout kbuild
Best Regards

Thank you, that is much easier.
I'm very impressed with your efforts here - the commits are clean and
easy to understand. I have been through them in turn. I have a few
minor comments...
I see this error turn up in commit 34 (it is fixed in 38):
34: Kbuild: change out-of-tree building

What will happen with the 'FIX ME's that are generated? e.g.:

Have you done any comparison on build times?

It looks like nand_spl boards are
broken at 29 and fixed at 31.
I will fix this problem at v2.

Sandbox is broken at 34 and fixed at 38.
I will fix this problem too at v2.
buildman is also reporting something about bf561-acvilon and cm-bf537u.
But as long as I tested, I believe it is unrelated to Kbuild.
Sonic Zhang posted some patches to fix errors/warnings of Blackfin
boards.
Please check this again after u-boot-blackfin/mater is merged.

I was thinking to do something about this after Kconfig.
Some Blackfin, M68K boards want to compile lib, lib/lzma, lib/zlib
with -O2 option and other sources with -Os option.
I think this feature is WANT, not MUST.
If this feature deserves maintainance,
how about adding new CONFIG macro like this?
config CC_OPTIMIZE_LIBS_FOR_SPEED
bool "Optimize libraries for speed"
help
Enabling this option will pass "-O2" when compiling C sources
under lib/ directory even if -Os is given to the whole sources.
If unsure, say N.
And add the following line to lib/Makefile.
subdir-ccflags-$(CONFIG_OPTIMIZE_LIBS_FOR_SPEED) += -O2
> Have you done any comparison on build times?
Do you mean Kbuild is slower than U-Boot conventional build system?

No, faster. It could just be that it works better in parallel.
