Makefile: Improve generated_defconfig file handling

Commit 2027e99e61aa ("Makefile: Run defconfig files through the C
preprocessor") adds `generated_defconfig' file, but fails to clean that
up. It might be useful to have that file around after `make' is done,
but it's better to clean that up on `make clean'. Also we probably want
to hide it in `git status' list. This patch makes the described changes,
and also adds `-P' parameter to the CPP command that produces the
`generated_defconfig' to avoid generating linemarkers.

tools: gitignore: Fix tools/generated path

'git status' shows 'tools/generated/' after running the build, which is
wrong. The corresponding .gitignore rule was already added in commit
c623642d29be ("Adjust gitignore for tools/generated/"), but because of
superfluous 'tools/' part it wasn't in effect. Remove incorrect 'tools/'
part to fix it.

While at it, remove tools/ path incorrectly added to the top-level
.gitignore in commit 801c482207c7 (".gitignore: ignore misc include,
simple-bin, and tools/generated build artifacts"), as it's required in
the comment on the top of .gitignore:

# NOTE! Don't add files that are generated in specific
# subdirectories here. Add them in the ".gitignore" file
# in that subdirectory instead.

kconfig: re-sync with Linux 4.17-rc4

Align Kconfig to Linux 4.17-rc4 with minimal impact on non-kconfig files.

Previous Kconfig sync was done by commit bf7ab1e70fd762 ("kconfig:
re-sync with Linux 4.10") and it achieved almost perfect alignment with
a few (intended) exceptions, caused by below U-boot commits:

[A] v2015.04 5f9eb2207500 ("kbuild: remove scripts/multiconfig.sh")
[B] v2015.07 20c20826efab ("Kconfig: Enable usage of escape char '\' in string values")
[C] v2016.01 da58dec86616 ("Various Makefiles: Add SPDX-License-Identifier tags")
[D] v2016.03 5b8031ccb4ed ("Add more SPDX-License-Identifier tags")
[E] v2016.03 192bc6948b02 ("Fix GCC format-security errors and convert sprintfs.")

Here is the list of Kconfig commits which followed the v4.10 alignment:

[F] v2018.01 0931ed3c0d0f ("kconfig/symbol.c: use correct pointer type argument for sizeof")
[G] v2018.03 1414e09b4f25 ("kconfig: revert change that was not needed for -Wformat-security")
[H] v2018.05 83d290c56fab ("SPDX: Convert all of our single license tags to Linux Kernel style")

Commit [F] was subsequently applied to Linux kernel as commit [I]
with the same patch id, so it won't contribute to further misalignment.

[I] v4.15-rc1 88127dae6ed9 ("kconfig/symbol.c: use correct pointer type argument for sizeof")

Commit [G] is a Kconfig-specific revert of commit [E].
Commit [H] relocated and reformatted the license doing no functional change.

In summary, the only functional change that makes U-boot Kconfig
diverge from Linux Kconfig is commit [B]. After a brief analysis,
the purpose of [B] seems to be placing "\n" literals in string symbols
like CONFIG_AUTOBOOT_PROMPT="autoboot in %d seconds\n" in order to pass
them directly to printf and expect correct output at runtime. Currently,
Linux doesn't seem to have this requirement, so for the moment [B] looks
like a U-boot specific feature/fix. From point of view of further Kconfig
alignment and backporting efforts, it is highly desired that commits
like [B] are propagated to Linux and any Kconfig fixes/features are
contributed to Linux kernel first. This specific Kconfig re-sync just
keeps [B] in place.

Contrary to 4.10 Kconfig re-sync (which achieves zero non-kconfig
changes), 4.17-rc4 re-sync does some amount of updates in Kbuild
(striving to keep them at minimum), due to a number of reasons:
* Kbuild is affected by the removal of Kconfig "*shipped" files and now
requires flex and bison pre-installed on the host.
* PYTHON{2,3} variables are defined in top-level Makefile as
prerequisite for running the newly developed Kconfig unit tests.
* silentoldconfig becomes an "internal implementation detail" deprecated
for external use, being renamed to syncconfig.

The exact non-kconfig files touched by this commit are:

$ git show --format="" --stat -- ':!scripts/kconfig'
.gitignore | 2 ++
Makefile | 9 +++++++--
scripts/Makefile.build | 11 +++++++++++
scripts/Makefile.lib | 41 ++++++++++++-----------------------------

The imported Linux commits touching the above files are:

c054be10ffdbd5 ("remove gperf left-overs from build system")
73a4f6dbe70a1b ("kbuild: add LEX and YACC variables")
033dba2ec06c47 ("kbuild: prepare to remove C files pre-generated by flex and bison")
eea199b445f64c ("kbuild: remove unnecessary LEX_PREFIX and YACC_PREFIX")
e71de5ee08dcb0 ("kbuild: remove remaining use of undefined YACC_PREFIX")
d59fbbd09d5d6b ("kbuild: replace hardcoded bison in cmd_bison_h with $(YACC)")
911a91c39cabcb H ("kconfig: rename silentoldconfig to syncconfig")
59889300274569 (".gitignore: move *.lex.c *.tab.[ch] patterns to the top-level .gitignore")
9a8dfb394c0467 ("kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level Makefile")
833e622459432e H ("genksyms: generate lexer and parser during build instead of shipping")
b23d1a241f4eb4 H ("kbuild: add %.lex.c and %.tab.[ch] to 'targets' automatically")
e9781b52d4e0e3 H ("kbuild: add PYTHON2 and PYTHON3 variables")

The commits marked with 'H' are assessed as "hard" (build will fail)
prerequisites and the rest of them are assessed as "soft" prerequisites
for the re-sync. In spite of relatively high number of non-H commits,
they belong to this Kconfig update topic-wise and decrease the number of
cherry pick conflicts for many commits in this series. Additional effort
can be put in eliminating the soft prerequisites, if really needed.

The commits which contributed to this Kconfig re-sync are listed below.
Whenever a conflict resolution has been performed (mostly by hand, but
sometimes automatically by git), it is revealed by the '!' sign in the
second column, which means a patch id mismatch between Linux and U-boot

The current Kconfig update generates below build-time warnings:
YACC scripts/dtc/dtc-parser.tab.h
scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr]
YACC scripts/dtc/dtc-parser.tab.c
scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr]

This seems to happen because the Kbuild updates apparently didn't make
room for both "*shipped"-based builds and flex/bison-based builds. A
similar problem has been reported for genksyms parser in v4.17-rc1
commit 833e622459432e ("genksyms: generate lexer and parser during build
instead of shipping"). I have figured out empirically that the warnings
are healed after updating the in-tree U-boot DTC to upstream v1.4.6-9,
same as done by Linux v4.17-rc1 commit 9130ba88464032 ("scripts/dtc:
Update to upstream version v1.4.6-9-gaadd0b65c987"). Whether fixing the
DTC-related yacc warnings should be done together with the Kconfig
re-sync, I would like to hear from community.

My testing was limited to:
- make defconfig all
- make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- r8a7795_ulcb_defconfig all
- comparing .config before and after the re-sync
- running the newly imported Kconfig unit tests as seen below:

kconfig: switch to Kconfig

This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.

Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.

Usage:

Run "make <board>_defconfig" to do the board configuration.

It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.

You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.

Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.

The generic syntax of configuration targets for SPL, TPL is:

<target_image>/<config_command>

Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.

When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)

For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.

By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.

Prior to Kconfig, we used C headers to define a set of configs.

We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.

In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

spl: common: Properly ignore spl/Makefile in .gitignore

The spl directory is ignored by git as these objects are created
during spl creation. The only file not created is the Makefile.

This file can be modified and checked in via git.

Due to the order of rule precedence having the whole directory
ignored first then indicating not to ignore the Makefile is not correct
the message to force adding the Makefile is still shown.

So reorder the .gitignore for the Makefile and indicate that the Makefile
does not need to be ignored first and then indicate everything else in spl

dts/Makefile: simplify dtc invocation

The invocation of dtc is significantly more complex that it could be,
in order to work around an issue on old versions of dtc, which print
a message to stdout every time they run.

Remove this workaround, on the assumption that people have or will
upgrade to a newer version of dtc. This simplifies the build rule
significantly.

Related, split the invocation of cpp and dtc into separate commands
rather than a pipeline, so that if either fail, it is detected. This has
the nice benefit of saving off the result of the pre-processing step,
allowing it to be easily inspected.

Assuming a new enough dtc (which an earlier patch enforces), dtc will
parse #line directives in its input file, and generate correct file and
line numbers in error messages, even though cpp is unconditionally
applied to its input file.

common: Add symbol handling for generic lists into Makefile

This patch adds essential components for generation of the contents of
the linker section that is used by the linker-generated array. All of
the contents is held in a separate file, u-boot.lst, which is generated
at runtime just before U-Boot is linked.

The purpose of this code is to especially generate the appropriate
boundary symbols around each subsection in the section carrying the
linker-generated arrays. Obviously, the interim linker code for actual
placement of the variables into the section is generated too. The
generated file, u-boot.lst, is included into u-boot.lds via the linker
INCLUDE directive in u-boot.lds .

Adjustments are made in the Makefile and spl/Makefile so that the
u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

include/asm-offsets.h: automatically generate assembler constants

A recurrent issue is that certain C level constructs like sizeof() or
offsetof() cannot be used in assembler files, which is inconvenient
when such constructs are used in the definition of macro names etc.

To avoid duplication of such definitions (and thus another cause of
problems), we adapt the Linux way to automatically generate the
respective definitions from the respective C header files.

In Linux, this is implemented in include/linux/kbuild.h, Kbuild, and
arch/*/kernel/asm-offsets.c; we adapt the code from the Linux v2.6.36
kernel tree.

We also copy the concept of the include/generated/ directory which can
be used to hold other automatically generated files as well.

We start with an architecture-independent lib/asm-offsets.c which
generates include/generated/generic-asm-offsets.h (included by
include/asm-offsets.h, which is what will be referred to in the actual
source code). Later this may be extended by architecture-specific
arch/*/lib/asm-offsets.c files that will generate a
include/generated/asm-offsets.h.

kconfig: re-sync with Linux 4.17-rc4

Align Kconfig to Linux 4.17-rc4 with minimal impact on non-kconfig files.

Previous Kconfig sync was done by commit bf7ab1e70fd762 ("kconfig:
re-sync with Linux 4.10") and it achieved almost perfect alignment with
a few (intended) exceptions, caused by below U-boot commits:

[A] v2015.04 5f9eb2207500 ("kbuild: remove scripts/multiconfig.sh")
[B] v2015.07 20c20826efab ("Kconfig: Enable usage of escape char '\' in string values")
[C] v2016.01 da58dec86616 ("Various Makefiles: Add SPDX-License-Identifier tags")
[D] v2016.03 5b8031ccb4ed ("Add more SPDX-License-Identifier tags")
[E] v2016.03 192bc6948b02 ("Fix GCC format-security errors and convert sprintfs.")

Here is the list of Kconfig commits which followed the v4.10 alignment:

[F] v2018.01 0931ed3c0d0f ("kconfig/symbol.c: use correct pointer type argument for sizeof")
[G] v2018.03 1414e09b4f25 ("kconfig: revert change that was not needed for -Wformat-security")
[H] v2018.05 83d290c56fab ("SPDX: Convert all of our single license tags to Linux Kernel style")

Commit [F] was subsequently applied to Linux kernel as commit [I]
with the same patch id, so it won't contribute to further misalignment.

[I] v4.15-rc1 88127dae6ed9 ("kconfig/symbol.c: use correct pointer type argument for sizeof")

Commit [G] is a Kconfig-specific revert of commit [E].
Commit [H] relocated and reformatted the license doing no functional change.

In summary, the only functional change that makes U-boot Kconfig
diverge from Linux Kconfig is commit [B]. After a brief analysis,
the purpose of [B] seems to be placing "\n" literals in string symbols
like CONFIG_AUTOBOOT_PROMPT="autoboot in %d seconds\n" in order to pass
them directly to printf and expect correct output at runtime. Currently,
Linux doesn't seem to have this requirement, so for the moment [B] looks
like a U-boot specific feature/fix. From point of view of further Kconfig
alignment and backporting efforts, it is highly desired that commits
like [B] are propagated to Linux and any Kconfig fixes/features are
contributed to Linux kernel first. This specific Kconfig re-sync just
keeps [B] in place.

Contrary to 4.10 Kconfig re-sync (which achieves zero non-kconfig
changes), 4.17-rc4 re-sync does some amount of updates in Kbuild
(striving to keep them at minimum), due to a number of reasons:
* Kbuild is affected by the removal of Kconfig "*shipped" files and now
requires flex and bison pre-installed on the host.
* PYTHON{2,3} variables are defined in top-level Makefile as
prerequisite for running the newly developed Kconfig unit tests.
* silentoldconfig becomes an "internal implementation detail" deprecated
for external use, being renamed to syncconfig.

The exact non-kconfig files touched by this commit are:

$ git show --format="" --stat -- ':!scripts/kconfig'
.gitignore | 2 ++
Makefile | 9 +++++++--
scripts/Makefile.build | 11 +++++++++++
scripts/Makefile.lib | 41 ++++++++++++-----------------------------

The imported Linux commits touching the above files are:

c054be10ffdbd5 ("remove gperf left-overs from build system")
73a4f6dbe70a1b ("kbuild: add LEX and YACC variables")
033dba2ec06c47 ("kbuild: prepare to remove C files pre-generated by flex and bison")
eea199b445f64c ("kbuild: remove unnecessary LEX_PREFIX and YACC_PREFIX")
e71de5ee08dcb0 ("kbuild: remove remaining use of undefined YACC_PREFIX")

e9781b52d4e0e3 H ("kbuild: add PYTHON2 and PYTHON3 variables")

The commits marked with 'H' are assessed as "hard" (build will fail)
prerequisites and the rest of them are assessed as "soft" prerequisites
for the re-sync. In spite of relatively high number of non-H commits,
they belong to this Kconfig update topic-wise and decrease the number of
cherry pick conflicts for many commits in this series. Additional effort
can be put in eliminating the soft prerequisites, if really needed.

The commits which contributed to this Kconfig re-sync are listed below.
Whenever a conflict resolution has been performed (mostly by hand, but
sometimes automatically by git), it is revealed by the '!' sign in the
second column, which means a patch id mismatch between Linux and U-boot

The current Kconfig update generates below build-time warnings:
YACC scripts/dtc/dtc-parser.tab.h
scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr]
YACC scripts/dtc/dtc-parser.tab.c
scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr]

This seems to happen because the Kbuild updates apparently didn't make
room for both "*shipped"-based builds and flex/bison-based builds. A
similar problem has been reported for genksyms parser in v4.17-rc1
commit 833e622459432e ("genksyms: generate lexer and parser during build
instead of shipping"). I have figured out empirically that the warnings
are healed after updating the in-tree U-boot DTC to upstream v1.4.6-9,
same as done by Linux v4.17-rc1 commit 9130ba88464032 ("scripts/dtc:
Update to upstream version v1.4.6-9-gaadd0b65c987"). Whether fixing the
DTC-related yacc warnings should be done together with the Kconfig
re-sync, I would like to hear from community.

My testing was limited to:
- make defconfig all
- make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- r8a7795_ulcb_defconfig all
- comparing .config before and after the re-sync
- running the newly imported Kconfig unit tests as seen below:

kconfig: switch to Kconfig

This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.

Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.

Usage:

Run "make <board>_defconfig" to do the board configuration.

It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.

You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.

Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.

The generic syntax of configuration targets for SPL, TPL is:

<target_image>/<config_command>

Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.

When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)

For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.

By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.

Prior to Kconfig, we used C headers to define a set of configs.

We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.

In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

spl: common: Properly ignore spl/Makefile in .gitignore

The spl directory is ignored by git as these objects are created
during spl creation. The only file not created is the Makefile.

This file can be modified and checked in via git.

Due to the order of rule precedence having the whole directory
ignored first then indicating not to ignore the Makefile is not correct
the message to force adding the Makefile is still shown.

So reorder the .gitignore for the Makefile and indicate that the Makefile
does not need to be ignored first and then indicate everything else in spl
should be ignored after wards.

dts/Makefile: simplify dtc invocation

The invocation of dtc is significantly more complex that it could be,
in order to work around an issue on old versions of dtc, which print
a message to stdout every time they run.

Remove this workaround, on the assumption that people have or will
upgrade to a newer version of dtc. This simplifies the build rule
significantly.

Related, split the invocation of cpp and dtc into separate commands
rather than a pipeline, so that if either fail, it is detected. This has
the nice benefit of saving off the result of the pre-processing step,
allowing it to be easily inspected.

Assuming a new enough dtc (which an earlier patch enforces), dtc will
parse #line directives in its input file, and generate correct file and
line numbers in error messages, even though cpp is unconditionally
applied to its input file.

common: Add symbol handling for generic lists into Makefile

This patch adds essential components for generation of the contents of
the linker section that is used by the linker-generated array. All of
the contents is held in a separate file, u-boot.lst, which is generated
at runtime just before U-Boot is linked.

The purpose of this code is to especially generate the appropriate
boundary symbols around each subsection in the section carrying the
linker-generated arrays. Obviously, the interim linker code for actual
placement of the variables into the section is generated too. The
generated file, u-boot.lst, is included into u-boot.lds via the linker
INCLUDE directive in u-boot.lds .

Adjustments are made in the Makefile and spl/Makefile so that the
u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

include/asm-offsets.h: automatically generate assembler constants

A recurrent issue is that certain C level constructs like sizeof() or
offsetof() cannot be used in assembler files, which is inconvenient
when such constructs are used in the definition of macro names etc.

To avoid duplication of such definitions (and thus another cause of
problems), we adapt the Linux way to automatically generate the
respective definitions from the respective C header files.

In Linux, this is implemented in include/linux/kbuild.h, Kbuild, and
arch/*/kernel/asm-offsets.c; we adapt the code from the Linux v2.6.36
kernel tree.

We also copy the concept of the include/generated/ directory which can
be used to hold other automatically generated files as well.

We start with an architecture-independent lib/asm-offsets.c which
generates include/generated/generic-asm-offsets.h (included by
include/asm-offsets.h, which is what will be referred to in the actual
source code). Later this may be extended by architecture-specific
arch/*/lib/asm-offsets.c files that will generate a
include/generated/asm-offsets.h.

kconfig: re-sync with Linux 4.17-rc4

Align Kconfig to Linux 4.17-rc4 with minimal impact on non-kconfig files.

Previous Kconfig sync was done by commit bf7ab1e70fd762 ("kconfig:
re-sync with Linux 4.10") and it achieved almost perfect alignment with
a few (intended) exceptions, caused by below U-boot commits:

[A] v2015.04 5f9eb2207500 ("kbuild: remove scripts/multiconfig.sh")
[B] v2015.07 20c20826efab ("Kconfig: Enable usage of escape char '\' in string values")
[C] v2016.01 da58dec86616 ("Various Makefiles: Add SPDX-License-Identifier tags")
[D] v2016.03 5b8031ccb4ed ("Add more SPDX-License-Identifier tags")
[E] v2016.03 192bc6948b02 ("Fix GCC format-security errors and convert sprintfs.")

Here is the list of Kconfig commits which followed the v4.10 alignment:

[F] v2018.01 0931ed3c0d0f ("kconfig/symbol.c: use correct pointer type argument for sizeof")
[G] v2018.03 1414e09b4f25 ("kconfig: revert change that was not needed for -Wformat-security")
[H] v2018.05 83d290c56fab ("SPDX: Convert all of our single license tags to Linux Kernel style")

Commit [F] was subsequently applied to Linux kernel as commit [I]
with the same patch id, so it won't contribute to further misalignment.

[I] v4.15-rc1 88127dae6ed9 ("kconfig/symbol.c: use correct pointer type argument for sizeof")

Commit [G] is a Kconfig-specific revert of commit [E].
Commit [H] relocated and reformatted the license doing no functional change.

In summary, the only functional change that makes U-boot Kconfig
diverge from Linux Kconfig is commit [B]. After a brief analysis,
the purpose of [B] seems to be placing "\n" literals in string symbols
like CONFIG_AUTOBOOT_PROMPT="autoboot in %d seconds\n" in order to pass
them directly to printf and expect correct output at runtime. Currently,
Linux doesn't seem to have this requirement, so for the moment [B] looks
like a U-boot specific feature/fix. From point of view of further Kconfig
alignment and backporting efforts, it is highly desired that commits
like [B] are propagated to Linux and any Kconfig fixes/features are
contributed to Linux kernel first. This specific Kconfig re-sync just
keeps [B] in place.

Contrary to 4.10 Kconfig re-sync (which achieves zero non-kconfig
changes), 4.17-rc4 re-sync does some amount of updates in Kbuild
(striving to keep them at minimum), due to a number of reasons:
* Kbuild is affected by the removal of Kconfig "*shipped" files and now
requires flex and bison pre-installed on the host.
* PYTHON{2,3} variables are defined in top-level Makefile as
prerequisite for running the newly developed Kconfig unit tests.
* silentoldconfig becomes an "internal implementation detail" deprecated
for external use, being renamed to syncconfig.

The exact non-kconfig files touched by this commit are:

.gitignore | 2 ++

The commits marked with 'H' are assessed as "hard" (build will fail)
prerequisites and the rest of them are assessed as "soft" prerequisites
for the re-sync. In spite of relatively high number of non-H commits,
they belong to this Kconfig update topic-wise and decrease the number of
cherry pick conflicts for many commits in this series. Additional effort
can be put in eliminating the soft prerequisites, if really needed.

The commits which contributed to this Kconfig re-sync are listed below.
Whenever a conflict resolution has been performed (mostly by hand, but
sometimes automatically by git), it is revealed by the '!' sign in the

The current Kconfig update generates below build-time warnings:

YACC scripts/dtc/dtc-parser.tab.c
scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr]

This seems to happen because the Kbuild updates apparently didn't make
room for both "*shipped"-based builds and flex/bison-based builds. A
similar problem has been reported for genksyms parser in v4.17-rc1
commit 833e622459432e ("genksyms: generate lexer and parser during build
instead of shipping"). I have figured out empirically that the warnings
are healed after updating the in-tree U-boot DTC to upstream v1.4.6-9,
same as done by Linux v4.17-rc1 commit 9130ba88464032 ("scripts/dtc:
Update to upstream version v1.4.6-9-gaadd0b65c987"). Whether fixing the
DTC-related yacc warnings should be done together with the Kconfig
re-sync, I would like to hear from community.

My testing was limited to:
- make defconfig all
- make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- r8a7795_ulcb_defconfig all
- comparing .config before and after the re-sync
- running the newly imported Kconfig unit tests as seen below:

kconfig: switch to Kconfig

This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.

Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.

Usage:

Run "make <board>_defconfig" to do the board configuration.

It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.

You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.

Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.

The generic syntax of configuration targets for SPL, TPL is:

<target_image>/<config_command>

Here, <target_image> is either 'spl' or 'tpl'
<config_command> is 'config', 'menuconfig', 'xconfig', etc.

When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)

For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.

By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.

Prior to Kconfig, we used C headers to define a set of configs.

We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.

In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

spl: common: Properly ignore spl/Makefile in .gitignore

The spl directory is ignored by git as these objects are created
during spl creation. The only file not created is the Makefile.

This file can be modified and checked in via git.

Due to the order of rule precedence having the whole directory
ignored first then indicating not to ignore the Makefile is not correct
the message to force adding the Makefile is still shown.

So reorder the .gitignore for the Makefile and indicate that the Makefile
does not need to be ignored first and then indicate everything else in spl

dts/Makefile: simplify dtc invocation

The invocation of dtc is significantly more complex that it could be,
in order to work around an issue on old versions of dtc, which print
a message to stdout every time they run.

Remove this workaround, on the assumption that people have or will
upgrade to a newer version of dtc. This simplifies the build rule
significantly.

Related, split the invocation of cpp and dtc into separate commands
rather than a pipeline, so that if either fail, it is detected. This has
the nice benefit of saving off the result of the pre-processing step,
allowing it to be easily inspected.

Assuming a new enough dtc (which an earlier patch enforces), dtc will
parse #line directives in its input file, and generate correct file and
line numbers in error messages, even though cpp is unconditionally
applied to its input file.

the contents is held in a separate file, u-boot.lst, which is generated
at runtime just before U-Boot is linked.

The purpose of this code is to especially generate the appropriate
boundary symbols around each subsection in the section carrying the
linker-generated arrays. Obviously, the interim linker code for actual
placement of the variables into the section is generated too. The
generated file, u-boot.lst, is included into u-boot.lds via the linker
INCLUDE directive in u-boot.lds .

Adjustments are made in the Makefile and spl/Makefile so that the
u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

Adjust dependency rules to permit per-file flags

The dependency rules are currently done in a shell 'for' loop. This does not
permit Makefile variables to adjust preprocessor flags as is done with normal
compile flags, using the CFLAGS_path/file.o syntax.

This change moves the dependency generation into the Makefile itself, and
permits a CPPFLAGS_path/file.o to adjust preprocessor flags on a file or
directory basis.

The CPPFLAGS_... variable is also folded into CFLAGS during the build.

include/asm-offsets.h: automatically generate assembler constants

A recurrent issue is that certain C level constructs like sizeof() or
offsetof() cannot be used in assembler files, which is inconvenient
when such constructs are used in the definition of macro names etc.

To avoid duplication of such definitions (and thus another cause of
problems), we adapt the Linux way to automatically generate the
respective definitions from the respective C header files.

In Linux, this is implemented in include/linux/kbuild.h, Kbuild, and
arch/*/kernel/asm-offsets.c; we adapt the code from the Linux v2.6.36
kernel tree.

We also copy the concept of the include/generated/ directory which can
be used to hold other automatically generated files as well.

We start with an architecture-independent lib/asm-offsets.c which
generates include/generated/generic-asm-offsets.h (included by
include/asm-offsets.h, which is what will be referred to in the actual
source code). Later this may be extended by architecture-specific
arch/*/lib/asm-offsets.c files that will generate a
include/generated/asm-offsets.h.

kconfig: re-sync with Linux 4.17-rc4

Align Kconfig to Linux 4.17-rc4 with minimal impact on non-kconfig files.

Previous Kconfig sync was done by commit bf7ab1e70fd762 ("kconfig:
re-sync with Linux 4.10") and it achieved almost perfect alignment with
a few (intended) exceptions, caused by below U-boot commits:

[A] v2015.04 5f9eb2207500 ("kbuild: remove scripts/multiconfig.sh")
[B] v2015.07 20c20826efab ("Kconfig: Enable usage of escape char '\' in string values")
[C] v2016.01 da58dec86616 ("Various Makefiles: Add SPDX-License-Identifier tags")
[D] v2016.03 5b8031ccb4ed ("Add more SPDX-License-Identifier tags")
[E] v2016.03 192bc6948b02 ("Fix GCC format-security errors and convert sprintfs.")

Here is the list of Kconfig commits which followed the v4.10 alignment:

[F] v2018.01 0931ed3c0d0f ("kconfig/symbol.c: use correct pointer type argument for sizeof")
[G] v2018.03 1414e09b4f25 ("kconfig: revert change that was not needed for -Wformat-security")
[H] v2018.05 83d290c56fab ("SPDX: Convert all of our single license tags to Linux Kernel style")

Commit [F] was subsequently applied to Linux kernel as commit [I]
with the same patch id, so it won't contribute to further misalignment.

[I] v4.15-rc1 88127dae6ed9 ("kconfig/symbol.c: use correct pointer type argument for sizeof")

Commit [G] is a Kconfig-specific revert of commit [E].
Commit [H] relocated and reformatted the license doing no functional change.

In summary, the only functional change that makes U-boot Kconfig
diverge from Linux Kconfig is commit [B]. After a brief analysis,
the purpose of [B] seems to be placing "\n" literals in string symbols
like CONFIG_AUTOBOOT_PROMPT="autoboot in %d seconds\n" in order to pass
them directly to printf and expect correct output at runtime. Currently,
Linux doesn't seem to have this requirement, so for the moment [B] looks
like a U-boot specific feature/fix. From point of view of further Kconfig
alignment and backporting efforts, it is highly desired that commits
like [B] are propagated to Linux and any Kconfig fixes/features are
contributed to Linux kernel first. This specific Kconfig re-sync just
keeps [B] in place.

Contrary to 4.10 Kconfig re-sync (which achieves zero non-kconfig
changes), 4.17-rc4 re-sync does some amount of updates in Kbuild
(striving to keep them at minimum), due to a number of reasons:
* Kbuild is affected by the removal of Kconfig "*shipped" files and now
requires flex and bison pre-installed on the host.
* PYTHON{2,3} variables are defined in top-level Makefile as
prerequisite for running the newly developed Kconfig unit tests.
* silentoldconfig becomes an "internal implementation detail" deprecated
for external use, being renamed to syncconfig.

The exact non-kconfig files touched by this commit are:

$ git show --format="" --stat -- ':!scripts/kconfig'
.gitignore | 2 ++
Makefile | 9 +++++++--
scripts/Makefile.build | 11 +++++++++++
scripts/Makefile.lib | 41 ++++++++++++-----------------------------

The imported Linux commits touching the above files are:

c054be10ffdbd5 ("remove gperf left-overs from build system")
73a4f6dbe70a1b ("kbuild: add LEX and YACC variables")
033dba2ec06c47 ("kbuild: prepare to remove C files pre-generated by flex and bison")

e71de5ee08dcb0 ("kbuild: remove remaining use of undefined YACC_PREFIX")

e9781b52d4e0e3 H ("kbuild: add PYTHON2 and PYTHON3 variables")

The commits marked with 'H' are assessed as "hard" (build will fail)
prerequisites and the rest of them are assessed as "soft" prerequisites
for the re-sync. In spite of relatively high number of non-H commits,
they belong to this Kconfig update topic-wise and decrease the number of
cherry pick conflicts for many commits in this series. Additional effort
can be put in eliminating the soft prerequisites, if really needed.

The commits which contributed to this Kconfig re-sync are listed below.
Whenever a conflict resolution has been performed (mostly by hand, but
sometimes automatically by git), it is revealed by the '!' sign in the
second column, which means a patch id mismatch between Linux and U-boot

The current Kconfig update generates below build-time warnings:
YACC scripts/dtc/dtc-parser.tab.h
scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr]
YACC scripts/dtc/dtc-parser.tab.c
scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr]

This seems to happen because the Kbuild updates apparently didn't make
room for both "*shipped"-based builds and flex/bison-based builds. A
similar problem has been reported for genksyms parser in v4.17-rc1
commit 833e622459432e ("genksyms: generate lexer and parser during build
instead of shipping"). I have figured out empirically that the warnings
are healed after updating the in-tree U-boot DTC to upstream v1.4.6-9,
same as done by Linux v4.17-rc1 commit 9130ba88464032 ("scripts/dtc:
Update to upstream version v1.4.6-9-gaadd0b65c987"). Whether fixing the
DTC-related yacc warnings should be done together with the Kconfig
re-sync, I would like to hear from community.

My testing was limited to:
- make defconfig all
- make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- r8a7795_ulcb_defconfig all
- comparing .config before and after the re-sync
- running the newly imported Kconfig unit tests as seen below:

$ make testconfig
