The Linux kernel moved to sphinx-based documentation and got rid of the
DocBook based documentation quite a while ago. Hence, the DocBook
documentation for U-Boot should be converted as well.
To achieve this, import the necessary files from Linux v4.17, and
convert the current DocBook documentation (three files altogether) to
sphinx/reStructuredText.
For now, all old DocBook documentation was merged into a single
handbook, tentatively named "U-Boot Hacker Manual".
For some source files, the documentation style was changed to comply
with kernel-doc; no functional changes were applied.

As many targets are now commonly built with gcc-6 or later (which
defaults to a newer C standard than older compilers), certain C
constructs are now being used as they produce more readable code. And
while all compilers that we support building with support the C11
standard (and GNU11) they do not default to that standard. Ensure that
we pass along -std=gnu11 when building.

Align Kconfig to Linux 4.17-rc4 with minimal impact on non-kconfig files.
Previous Kconfig sync was done by commit bf7ab1e70f ("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 5f9eb22075 ("kbuild: remove scripts/multiconfig.sh")
[B] v2015.07 20c20826ef ("Kconfig: Enable usage of escape char '\' in string values")
[C] v2016.01 da58dec866 ("Various Makefiles: Add SPDX-License-Identifier tags")
[D] v2016.03 5b8031ccb4 ("Add more SPDX-License-Identifier tags")
[E] v2016.03 192bc6948b ("Fix GCC format-security errors and convert sprintfs.")
Here is the list of Kconfig commits which followed the v4.10 alignment:
[F] v2018.01 0931ed3c0d ("kconfig/symbol.c: use correct pointer type argument for sizeof")
[G] v2018.03 1414e09b4f ("kconfig: revert change that was not needed for -Wformat-security")
[H] v2018.05 83d290c56f ("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 +++++++--

The imported Linux commits touching the above files are:

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.

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.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:

Following the conversion of the SPDX license tags, a number of files
compiled with -pedantic now generate warnings similar to the following
for using C99-style '//' comments in ISO C90 code:
tools/gen_eth_addr.c:1:1: warning: C++ style comments are not allowed in ISO C90
// SPDX-License-Identifier: GPL-2.0+
^
The SPDX comment-style change means that these files have adopted C99,
so need to change the language-standard to --std=gnu99 or --std=gnu11
to let the compiler know this.
As we now require GCC 6 or newer for the cross-compiler, the project has
implicitly moved the project to GNU11: let older GCC versions on various
Linux distros know to treat our host tools as GNU11 as well.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

The __FILE__ macro is used everywhere in U-Boot to locate the file
printing the log message, such as WARN_ON(), etc. If U-Boot is
built out of tree, this can be a long absolute path.
This is because Kbuild runs in the objtree instead of the srctree,
then __FILE__ is expanded to a file path prefixed with $(srctree)/.
A brand-new option from GCC, -fmacro-prefix-map, solves this problem.
If your compiler supports it, __FILE__ is the relative path from the
srctree regardless of O= option. This provides more readable log,
more reproducible builds, and smaller image size.

The current makefile logic disables creation of the
SPL.log/u-boot-ivt.img.log etc. files when V=1 is given on the command
line, the rationale presumably being that the user wants and gets the
information on the console.
However, from general principles, I don't think a higher V= level
should affect which build artifacts get generated (and certainly
shouldn't produce fewer). Concretely, it's also a problem that when
doing a V=1 build in a terminal, the relevant HAB blocks lines easily
drown in all the other V=1 output.
Moreover, build systems such as Yocto by default pass V=1, so in that
case the information gets hidden away in the do_compile log file, making
it nigh impossible to create a recipe for creating signed U-boot images
- I don't want to disable V=1, because having verbose output in the log
file is valuable when things go wrong, but OTOH trying to go digging in
the do_compile log file (and getting exactly the right lines) is not
pleasant to even think about.
So change the logic so that for V=0, the mkimage output is redirected
to MKIMAGEOUTPUT (which is also the current behaviour), while for any
other value of V, we _additionally_ write the information to make's
stdout, whatever that might be.

Modifying the default environment via CONFIG_EXTRA_ENV_SETTINGS is
somewhat inflexible, partly because the cpp language does not allow
appending to an existing macro. This prevents reuse of "environment
fragments" for different boards, which in turn makes maintaining that
environment consistently tedious and error-prone.
This implements a Kconfig option for allowing one to define the entire
default environment in an external file, which can then, for example, be
generated programmatically as part of a Yocto recipe, or simply be kept
in version control separately from the U-boot repository.

Most of architectures have .text section situated in the very beginning

xxx-ld ... -Ttext $(CONFIG_SYS_TEXT_BASE) ...

But there could be exceptions. For example:
1. In case of ARCv2 we want to put vectors table in its own section
.ivt in front of .text section which means we need either add an
offset to CONFIG_SYS_TEXT_BASE to compensate for .ivt or don't
pass "-Ttext" to the LD at all and specify link base in linker
script directly.
2. Some architectures even though have .text section in the very
beginning of the U-Boot image still use different symbols to
specify link-base:
* NIOS2: CONFIG_SYS_MONITOR_BASE (which I really like because
that exactly what makes sense - where out image starts but not
beginning of its .text section which just happened to match the
whole image beginning)
* EXTENSA: CONFIG_SYS_TEXT_ADDR
* X86: Which doesn't use CONFIG_SYS_MONITOR_BASE in case of EFI
otherwise sets explicit link base in u-boot.lds
I think that's good to allow for flexibility and don't require each and
every architecture or even platform to specify CONFIG_SYS_TEXT_BASE as well
as use it to set .text section location.
So let's only pass "-Ttext xxx" for those architectures who don't set
link-base explicitly in their linker scripts.

With CONFIG_SYS_INIT_SP_BSS_OFFSET enabled, the initial (pre-relocation)
stack is placed some distance after bss_start. The control DTB is appended
to the U-Boot binary at bss_start. If the DTB is too large, or the SP BSS
offset too small, then the initial stack could corrupt the DTB. Enhance
the Makefile to check whether this is likely to occur.

Update tegra to use binman for image creation. This still includes the
current Makefile logic, but a later patch will remove this. Three output
files are created, all of which combine
SPL and U-Boot:
u-boot-tegra.bin - standard image
u-boot-dtb-tegra.bin - same as u-boot-tegra.bin
u-boot-nodtb-target.bin - includes U-Boot without the appended device tree
The latter is useful for build systems where the device is appended later,
perhaps after being modified.

With commit 84d46e7e89 ("tools: env: allow to print U-Boot version")
the fw_env utilities need the version.h header file. Building only
the envtools in a pristine build directory will fail due to missing
header files.
Make sure the header files are a dependency of the envtools target.

When building on a multi-core machine for an SPL-enabled board that
also uses CONFIG_OF_EMBED, the following error can be encountered
due to a race condition:
make[3]: *** No rule to make target 'spl/dts/dt.dtb.o', needed by
'spl/dts/built-in.o'. Stop.
../scripts/Makefile.spl:364: recipe for target 'spl/dts' failed
make[2]: *** [spl/dts] Error 2
make[2]: *** Waiting for unfinished jobs....
A reliable way to trigger this race condition is to add "sleep 60" to
the end of the "arch-dtbs" rule's recipe in "dts/Makefile" and to build
U-Boot against a board which uses the CONFIG_OF_EMBED and CONFIG_SPL
options using "make -j8" or a similar command.
This commit corrects this race condition via the use of CONFIG_OF_EMBED
in the same way that commit 3c00a2c8b5 ("Makefile: Correct dependency
race condition with TPL") and commit 054b3a1e80 ("dm: Makefile: Build
of-platdata before SPL") use CONFIG_OF_SEPARATE.

Coccinelle is a program for static code analysis.
For details on Coccinelle see
http://coccinelle.lip6.fr/
Add scripts/coccicheck copied from Linux kernel v4.14.
The coccicheck script executes the tests *.cocci in
directory scripts/coccinelle by calling spatch.
In Makefile add a coccicheck target. You can use it with
make coccicheck MODE=<mode>
where mode in patch, report, context, org.
Add a copy of Linux v4.14 file Documentation/dev-tools/coccinelle.rst
as doc/README.coccinelle.

Currently, pylibfdt is always compiled if swig is installed on your
machine. It is really annoying because most of targets (excepts
x86, sunxi, rockchip) do not use dtoc or binman.
"checkbinman" and "checkdtoc" are wrong. It is odd that the final
build stage checks if we have built necessary tools. If your platform
depends on dtoc/binman, you must be able to build pylibfdt. If swig
is not installed, it should fail immediately.
I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be
property select:ed by platforms that need them. Kbuild will descend
into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.
Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.
I also rewrote the Makefile in a cleaner Kbuild style.
The scripts from the upstream have been moved as follows:
lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped
The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.
