Various DT and fwnode functions take a compatible string as a parameter.
These are often used in cases which don't have a driver, so they've been
missed.
The additional checks add about 400 more undocumented compatible
strings.

The 'dt_binding_check' target shouldn't depend on the kernel
configuration, but it has since commit 604a57ba9781 ("dt-bindings:
kbuild: Add separate target/dependency for processed-schema.json").
That is because CHECK_DT_BINDING make variable was dropped, but
scripts/dtc/Makefile was missed. The CHECK_DTBS variable can be used
instead.

Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:
src := $(obj)
When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.
This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.
To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.
Going forward, the variables used in Makefiles will have the following
meanings:
$(obj) - directory in the object tree
$(src) - directory in the source tree (changed by this commit)
$(objtree) - the top of the kernel object tree
$(srctree) - the top of the kernel source tree
Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).

The iglob function, which we use to find C source files in the kernel
tree, always follows symbolic links. This can cause unintentional
recursions whenever a symbolic link points to a parent directory. A
common scenario is building the kernel with the output set to a
directory inside the kernel tree, which will contain such a symlink.
Instead of using the iglob function, use os.walk to traverse the
directory tree, which by default doesn't follow symbolic links. fnmatch
is then used to match the glob on the filename, as well as ignore hidden
files (which were ignored by default with iglob).
This approach runs just as fast as using iglob.

Add a new flag, '--driver-match', to the dt-extract-compatibles script
that causes it to only print out compatibles that are expected to match
a driver. This output can then be used by tests to detect device probe
failures.
In order to filter the compatibles down to only ones that will match to
a driver, the following is considered:
- A compatible needs to show up in a driver's of_match_table for it to
be matched to a driver
- Compatibles that are used in both of_match_table and OF_DECLARE type
macros can't be expected to match to a driver and so are ignored.
One exception is CLK_OF_DECLARE_DRIVER, since it indicates that a
driver will also later probe, so compatibles in this macro are not
ignored.

annotations
The regex search for declarations of struct of_device_id was missing
cases that had a compiler annotation such as "__maybe_unused". Improve
the regex to allow for these. Use '\S' instead of specific characters to
shorten the regex. That also finds some more compatibles using '.'
characters.
Unfortunately, these changes add ~400 more compatibles without a
schema.

architectures as well, introduce a symlink to the RISC-V DT directory.

Add a make target, dt_compatible_check, to extract compatible strings
from kernel sources and check if they are documented by a schema.
At least version v2022.08 of dtschema with dt-check-compatible is
required.
This check can also be run manually on specific files or directories:
scripts/dtc/dt-extract-compatibles drivers/clk/ | \
xargs dt-check-compatible -v -s Documentation/devicetree/bindings/processed-schema.json
Currently, there are about 3800 undocumented compatible strings. Most of
these are cases where the binding is not yet converted (given there
are 1900 .txt binding files remaining).

Pull devicetree updates from Rob Herring:
- Add Krzysztof Kozlowski as co-maintainer for DT bindings providing
much needed help.
- DT schema validation now takes DTB files as input rather than
intermediate YAML files. This decouples the validation from the
source level syntax information. There's a bunch of schema fixes as a
result of switching to DTB based validation which exposed some errors
and incomplete schemas and examples.
- Kbuild improvements to explicitly warn users running 'make
dt_binding_check' on missing yamllint
- Expand DT_SCHEMA_FILES kbuild variable to take just a partial
filename or path instead of the full path to 1 file.
- Convert various bindings to schema format: mscc,vsc7514-switch,
multiple GNSS bindings, ahci-platform, i2c-at91, multiple UFS
bindings, cortina,gemini-sata-bridge, cortina,gemini-ethernet, Atmel

- New schemas for u-boot environment variable partition, TI clksel

- Vendor prefixes for Xen, HPE, deprecated Synopsys, deprecated

Switch the DT validation to use DTB files directly instead of a DTS to
YAML conversion.
The original motivation for supporting validation on DTB files was to
enable running validation on a running system (e.g. 'dt-validate
/sys/firmware/fdt') or other cases where the original source DTS is not
available.
The YAML format was not without issues. Using DTBs with the schema type
information solves some of those problems. The YAML format relies on the
DTS source level information including bracketing of properties, size
directives, and phandle tags all of which are lost in a DTB file. While
standardizing the bracketing is a good thing, it does cause a lot of
extra warnings and churn to fix them.
Another issue has been signed types are not validated correctly as sign
information is not propagated to YAML. Using the schema type information
allows for proper handling of signed types. YAML also can't represent
the full range of 64-bit integers as numbers are stored as floats by
most/all parsers.
The DTB validation works by decoding property values using the type
information in the schemas themselves. The main corner case this does
not work for is matrix types where neither dimension is fixed. For
now, checking the dimensions in these cases are skipped.

If unittest detects a problem it will print a warning or error message
to the console. Unittest also triggers warning and error messages from
other kernel code as a result of intentionally bad unittest data. This
has led to confusion as to whether the triggered messages are an
expected result of a test or whether there is a real problem that is
independent of unittest.
EXPECT messages were added to unittest to report each triggered message
that is expected, resulting in verbose console output.
scripts/dtc/of_unittest is a new program that processes the EXPECT
messages to determine whether the triggered messages occurred and
also removes the excess verbosity of the EXPECT messages. More
information is available from 'scripts/dtc/of_unittest_expect --help'.

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
This code was transformed with the help of Coccinelle:
(next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)
@@
identifier S, member, array;
type T1, T2;
@@
struct S {
...
T1 member;
T2 array[
- 0
];
};
UAPI and wireless changes were intentionally excluded from this patch
and will be sent out separately.

dtx_diff suggests to use <(...) syntax to pipe two inputs into it, but
this has never worked: The /proc/self/fds/... paths passed by the shell
will fail the `[ -f "${dtx}" ] && [ -r "${dtx}" ]` check in compile_to_dts,
but even with this check removed, the function cannot work: hexdump will
eat up the DTB magic, making the subsequent dtc call fail, as a pipe
cannot be rewound.
Simply remove this broken example, as there is already an alternative one
that works fine.

To build host programs, you need to add the program names to 'hostprogs'
to use the necessary build rule, but it is not enough to build them
because there is no dependency.
There are two types of host programs: built as the prerequisite of
another (e.g. gen_crc32table in lib/Makefile), or always built when
Kbuild visits the Makefile (e.g. genksyms in scripts/genksyms/Makefile).
The latter is typical in Makefiles under scripts/, which contains host
programs globally used during the kernel build. To build them, you need
to add them to both 'hostprogs' and 'always-y'.
This commit adds hostprogs-always-y as a shorthand.
The same applies to user programs. net/bpfilter/Makefile builds
bpfilter_umh on demand, hence always-y is unneeded. In contrast,
programs under samples/ are added to both 'userprogs' and 'always-y'
so they are always built when Kbuild visits the Makefiles.
userprogs-always-y works as a shorthand.

Commit 067c650c456e ("dtc: Use pkg-config to locate libyaml") added
'pkg-config --libs' to link libyaml installed in a non-standard
location.
yamltree.c includes <yaml.h>, but that commit did not add the search
path for <yaml.h>. If /usr/include/yaml.h does not exist, it fails to
build. A user can explicitly pass HOSTCFLAGS to work around it, but
the policy is not consistent.
There are two ways to deal with libraries in a non-default location.
[1] Use HOSTCFLAGS and HOSTLDFLAGS for additional search paths for
headers and libraries.
They are documented in Documentation/kbuild/kbuild.rst
$ make HOSTCFLAGS='-I <prefix>/include' HOSTLDFLAGS='-L <prefix>/lib'
[2] Use pkg-config
'pkg-config --cflags' for querying the header search path
'pkg-config --libs' for querying the lib and its path
If we go with pkg-config, use [2] consistently. Do not mix up
[1] and [2].

If you run 'make dtbs_check' without installing the libyaml package,
the error message "dtc needs libyaml ..." is shown.
This should be checked also for 'make dt_binding_check' because dtc
needs to validate *.example.dts extracted from *.yaml files.
It is missing since commit 4f0e3a57d6eb ("kbuild: Add support for DT
binding schema checks"), but this fix-up is applicable only after commit
e10c4321dc1e ("kbuild: allow to run dt_binding_check and dtbs_check

I gave the Fixes tag to the latter in case somebody is interested in
back-porting this.

Pull Kbuild updates from Masahiro Yamada:
"Build system:
- add CONFIG_UNUSED_KSYMS_WHITELIST, which will be useful to define a
fixed set of export symbols for Generic Kernel Image (GKI)
- allow to run 'make dt_binding_check' without .config
- use full schema for checking DT examples in *.yaml files
- make modpost fail for missing MODULE_IMPORT_NS(), which makes more
sense because we know the produced modules are never loadable
- Remove unused 'AS' variable
Kconfig:
- sanitize DEFCONFIG_LIST, and remove ARCH_DEFCONFIG from Kconfig
files
- relax the 'imply' behavior so that symbols implied by 'y' can
become 'm'
- make 'imply' obey 'depends on' in order to make 'imply' really weak
Misc:
- add documentation on building the kernel with Clang/LLVM
- revive __HAVE_ARCH_STRLEN for 32bit sparc to use optimized strlen()
- fix warning from deb-pkg builds when CONFIG_DEBUG_INFO=n
- various script and Makefile cleanups"

gcc 10 will default to -fno-common, which causes this error at link
time:
(.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
This is because both dtc-lexer as well as dtc-parser define the same
global symbol yyloc. Before with -fcommon those were merged into one
defintion. The proper solution would be to to mark this as "extern",
however that leads to:
dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]
26 | extern YYLTYPE yylloc;
| ^~~~~~
In file included from dtc-lexer.l:24:
dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here
127 | extern YYLTYPE yylloc;
| ^~~~~~
cc1: all warnings being treated as errors
which means the declaration is completely redundant and can just be
dropped.

The dt_binding_check target is located outside of the
'ifneq ($(dtstree),) ... endif' block.
So, you can run 'make dt_binding_check' on any architecture.
This makes a perfect sense because the dt-schema is arch-agnostic.
The only one problem I see is that scripts/dtc/dtc is not always built.
For example, ARCH=x86 defconfig does not define CONFIG_DTC. Kbuild
descends into scripts/dtc/ with doing nothing. Then, it fails to build
*.example.dt.yaml files.
Let's build scripts/dtc/dtc forcibly when running dt_binding_check.
The dt-schema does not depend on any CONFIG option either, so you
should be able to run dt_binding_check without the .config file.
Going forward, you can directly run 'make dt_binding_check' in a
pristine source tree.

In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.
It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.
This commit renames like follows:
always -> always-y
hostprogs-y -> hostprogs
So, scripts/Makefile will look like this:
always-$(CONFIG_BUILD_BIN2C) += ...
always-$(CONFIG_KALLSYMS) += ...
...
hostprogs := $(always-y) $(always-m)
I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.
The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.

with phandles"
This reverts upstream commit 18d7b2f4ee45fec422b7d82bab0b3c762ee907e4. A
revert in upstream dtc is pending.
This commit didn't work for properties such as 'interrupt-map' that have
phandle in the middle of an entry. It would also not work for a 0 or -1
phandle value that acts as a NULL.

Using Makefile's wildcard with absolute path to detect
the presence of libyaml results in false-positive
detection when cross-compiling e.g. in yocto environment.
The latter results in build error:

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

This adds the build infrastructure for checking DT binding schema
documents and validating dts files using the binding schema.
Check DT binding schema documents:
make dt_binding_check
Build dts files and check using DT binding schema:
make dtbs_check
Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to
use for validation. This makes it easier to find and fix errors
generated by a specific schema.
Currently, the validation targets are separate from a normal build to
avoid a hard dependency on the external DT schema project and because
there are lots of warnings generated.

There is nothing arch specific about building dtb files other than their
location under /arch/*/boot/dts/. Keeping each arch aligned is a pain.
The dependencies and supported targets are all slightly different.
Also, a cross-compiler for each arch is needed, but really the host
compiler preprocessor is perfectly fine for building dtbs. Move the
build rules to a common location and remove the arch specific ones. This
is done in a single step to avoid warnings about overriding rules.
The build dependencies had been a mixture of 'scripts' and/or 'prepare'.
These pull in several dependencies some of which need a target compiler
(specifically devicetable-offsets.h) and aren't needed to build dtbs.
All that is really needed is dtc, so adjust the dependencies to only be
dtc.
This change enables support 'dtbs_install' on some arches which were
missing the target.

Major changes are I2C and SPI bus checks, YAML output format (for
future validation), some new libfdt functions, and more libfdt
validation of dtbs.
The YAML addition adds an optional dependency on libyaml. pkg-config is
used to test for it and pkg-config became a kconfig dependency in 4.18.

It is tedious to specify extra compiler options for every file.
HOST_EXTRACFLAGS is useful to add options to all files in a
directory.
-I$(src)/libfdt is needed for all the files in this directory
to include libfdt_env.h etc. from scripts/dtc/libfdt/.
On the other hand, -I$(src) is used to include check-in headers
from generated C files. Thus, I added it only to dtc-lexer.lex.o
and dtc-parser.tab.o .

Cherry-picked from dtc upstream commit e1f139ea4900fd0324c646822b4061fec6e08321.
Having a 'bus-range' property for PCI bridges should not be required,
so remove the warning when missing. There was some confusion with the
Linux kernel printing a message that no property is present and the OS
assigned the bus number. This message was intended to be informational
rather than a warning.
When the firmware doesn't enumerate the PCI bus and leaves it up to the
OS to do, then it is perfectly fine for the OS to assign bus numbers
and bus-range is not necessary.
There are a few cases where bus-range is needed or useful as Arnd
Bergmann summarized:
- Traditionally Linux avoided using multiple PCI domains, but instead
configured separate PCI host bridges to have non-overlapping
bus ranges so we can present them to user space as a single
domain, and run the kernel without CONFIG_PCI_DOMAINS.
Specifying the bus ranges this way would and give stable bus
numbers across boots when the probe order is not fixed.
- On certain ARM64 systems, we must only use the first
128 bus numbers based on the way the IOMMU identifies
the device with truncated bus/dev/fn number. There are probably
others like this, with various limitations.
- To leave some room for hotplugged devices, each slot on
a host bridge can in theory get a range of bus numbers
that are available when assigning bus numbers at boot time

Pull asm-generic fixes from Arnd Bergmann:
"I have one regression fix for a minor build problem after the
architecture removal series, plus a rework of the barriers in the
readl/writel functions, thanks to work by Sinan Kaya:
This started from a discussion on the linuxpcc and rdma mailing
lists[1]. To summarize, we decided that architectures are responsible
to serialize readl() and writel() accesses on a device MMIO space
relative to DMA performed by that device.
This series provides a pessimistic implementation of that behavior for
asm-generic/io.h, which is in turn used by a number of architectures
(h8300, microblaze, nios2, openrisc, s390, sparc, um, unicore32, and
xtensa). Some of those presumably need no extra barriers, or something
weaker than rmb()/wmb(), and they are advised to override the new
default for better performance.
For inb()/outb(), the same barriers are used, but architectures might
want to add another barrier to outb() here if that can guarantee
non-posted behavior (some architectures can, others cannot do that).
The readl_relaxed()/writel_relaxed() family of functions retains the
existing behavior with no extra barriers"

Files generated by if_changed* must be added to 'targets' to include
*.cmd files. Otherwise, they would be regenerated every time.
The build system automatically adds objects to 'targets' where
appropriate, such as obj-y, extra-y, etc. but does nothing for
intermediate files. So, each Makefile needs to add them by itself.
There are some common cases where objects are generated by chained
rules. Lexers and parsers are compiled like follows:
%.lex.o <- %.lex.c <- %.l
%.tab.o <- %.tab.c <- %.y
They are common patterns, so it is reasonable to take care of them
in the core Makefile instead of requiring each Makefile to do so.
At this moment, you cannot delete 'target += zconf.lex.c' in the
Kconfig Makefile because zconf.lex.c is included from zconf.tab.c
instead of being compiled separately. It should be deleted after
Kconfig is more refactored.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

Remove proposed include path kernel/dts/, which was never implemented
for the dtb build.
For the diff case, each source file is compiled separately. For
each of those compiles, provide the location of the source file
as an include path, not the location of both source files.

dtc uses an incorrect format specifier for printing a uint64_t value.
uint64_t may be either 'unsigned long' or 'unsigned long long' depending
on the host architecture.
Fix this by using %llx and casting to unsigned long long, which ensures
that we always have a wide enough variable to print 64 bits of hex.

As the comparison uses process substitution to pass files after
conversion to DTS format, the diff header doesn't show the real
filenames, but the names of the file descriptors used:
--- /dev/fd/63 2017-06-22 11:21:47.531637188 +0200
+++ /dev/fd/62 2017-06-22 11:21:47.531637188 +0200
This is especially annoying when comparing a bunch of DT files in a
loop, as the output doesn't show a clue about which files it refers to.
Fix this by explicitly passing the original file names to the diff
command using the --label option, giving e.g.:
--- arch/arm/boot/dts/r8a7791-koelsch.dtb
+++ arch/arm/boot/dts/r8a7791-porter.dtb

We use a directory under arch/$ARCH/boot/dts as an include path
that has links outside of the subtree to find dt-bindings from under
include/dt-bindings. That's been working well, but new DT architectures
haven't been adding them by default.
Recently there's been a desire to share some of the DT material between
arm and arm64, which originally caused developers to create symlinks or
relative includes between the subtrees. This isn't ideal -- it breaks
if the DT files aren't stored in the exact same hierarchy as the kernel
tree, and generally it's just icky.
As a somewhat cleaner solution we decided to add a $ARCH/ prefix link
once, and allow DTS files to reference dtsi (and dts) files in other
architectures that way.
Original approach was to create these links under each architecture,
but it lead to the problem of recursive symlinks.
As a remedy, move the include link directories out of the architecture
trees into a common location. At the same time, they can now share one
directory and one dt-bindings/ link as well.

The default NetBSD package manager is pkgsrc and it installs Perl
along other third party programs under custom and configurable prefix.
The default prefix for binary prebuilt packages is /usr/pkg, and the
Perl executable lands in /usr/pkg/bin/perl.
This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's
the most portable solution that should work for almost everybody.
Perl's executable is detected automatically.
This change switches -w option passed to the executable with more
modern "use warnings;" approach. There is no functional change to the
default behavior.
While there, drop "require 5" from scripts/namespace.pl (Perl from 1994?).

Create script to diff device trees.
The device tree can be in any of the forms recognized by the dtc compiler:
- source
- binary blob
- file system tree (from /proc/devicetree)
If the device tree is a source file, then it is pre-processed in the
same way as it would be when built in the linux kernel source tree
before diffing.

The following script is used to import dtc upstream
into kernel. It was missing import of dtc/libfdt, with
this commit it will include the same.
Also, currently in arch and driver code that needs early access to
the flattened device tree it is necessary to add specific CFLAGS
so that when scripts/dtc/libfdt/libfdt.h is included the C
preprocessor is able to locate the libfdt versions of libfdt_env.h
and fdt.h without generating an error. So, this script replaces
angular brackets with quotation used to include header files
fdt.h and libfdt_env.h

Previously, the #line parsing regex ended with ({WS}+[0-9]+)?. The {WS}
could match line-break characters. If the #line directive did not contain
the optional flags field at the end, this could cause any integer data on
the next line to be consumed as part of the #line directive parsing. This
could cause syntax errors (i.e. #line parsing consuming the leading 0
from a hex literal 0x1234, leaving x1234 to be parsed as cell data,
which is a syntax error), or invalid compilation results (i.e. simply
consuming literal 1234 as part of the #line processing, thus removing it
from the cell data).
Fix this by replacing {WS} with [ \t] so that it can't match line-breaks.
Convert all instances of {WS}, even though the other instances should be
irrelevant for any well-formed #line directive. This is done for
consistency and ultimate safety.

This patch merely updates the generated dtc parser and lexer files to
the output generated by Bison 2.5. The previous versions were generated
from version 2.4.1. The only reason for this commit is to minimize the
diff on the next commit which fixes a bug in the DTC #line directive
parsing. Otherwise the Bison changes would be intermingled with the
functional changes.

The previous definition of for_each_*() would always include the very
first object within the list, irrespective of whether it was marked
deleted, since the deleted flag was not checked on the first object,
but only on any "next" object.
Fix for_each_*() to check the deleted flag in the loop body every
iteration to correct this.

The powerpc kernel always requires an Open Firmware like device tree
to supply device information. On systems without OF, this comes from
a flattened device tree blob. This blob is usually generated by dtc,
a tool which compiles a text description of the device tree into the
flattened format used by the kernel. Sometimes, the bootwrapper makes
small changes to the pre-compiled device tree blob (e.g. filling in
the size of RAM). To do this it uses the libfdt library.
Because these are only used on powerpc, the code for both these tools
is included under arch/powerpc/boot (these were imported and are
periodically updated from the upstream dtc tree).
However, the microblaze architecture, currently being prepared for
merging to mainline also uses dtc to produce device tree blobs. A few
other archs have also mentioned some interest in using dtc.
Therefore, this patch moves dtc and libfdt from arch/powerpc into
scripts, where it can be used by any architecture.
The vast bulk of this patch is a literal move, the rest is adjusting
the various Makefiles to use dtc and libfdt correctly from their new
locations.
