Back many years ago, we developed an Eclipse plugin that simplified
the usage of Buildroot toolchains. Enabling the BR2_ECLIPSE_REGISTER=y
was registering the Buildroot toolchain into a special file in your
HOME folder that the Eclipse plugin would recognize to allow to
directly use the Buildroot cross-compiler.
This Eclipse plugin has not been maintained for years. The last commit
in the repository dates back from September 2017. Since then Eclipse
has moved on, and the plugin is no longer compatible with current
versions of Eclipse.
Also, Eclipse is probably no longer that widely used in the embedded
Linux space, as other more modern IDEs have become more popular.
All in all, it's time to say good bye to this Eclipse integration.

We want to add more information in the manual about how a system created
with buildroot works overall. We currently already have a chapter about
SELinux, but we want to add more information like that, e.g. details
about how systemd in Buildroot works.
Create a new chapter "Integration topics" with an introductory blurb,
and move the SELinux topic under it (as a section rather than a
chapter).
"Integration topics" is not the best title, but we couldn't find
anything better.

Commit "45aabcddc5 utils/get-developers: really make it callable from
elsewhere than the toplevel directory" had a unforeseen side-effect:
the fact that check-developers with no arguments used to validate the
syntax of the DEVELOPERS no longer works. Indeed, the
parse_developers() call was moved *after* the check that verifies if
at least one action is passed. Due to this, the check-DEVELOPERS
verification in Gitlab CI, which invokes get-developers without
argument to validate the DEVELOPERS file... no longer does anything
useful.
In order to fix this, we introduce an explicit action in
get-developers to request the validation of the DEVELOPERS file. The
implementation is trivial, as the validation is already done by
calling parse_developers(), but at least now we have an action that
does "nothing", except execute until the validation is done.
This is also much more explicit than "invoke get-developers without
arguments to just do validation".
The initial investigation of the issue was done by Ricardo Martincoski
<ricardo.martincoski@gmail.com> and reported at
https://patchwork.ozlabs.org/project/buildroot/patch/20220528014832.289907-1-ricardo.martincoski@gmail.com/,
but we have chosen to introduce a separate -v option rather than
making the validation part of the existing -c action, which serves a
different purpose.

Whenever possible, we want to use the "shortcuts" provided by genimage
for the partition-type-uuid values:
- U for the EFI System Partition
- F for FAT32 partitions
- L for root filesystem partitions and other Linux filesystems
In follow-up commits, we will convert existing genimage.cfg to this
convention, except for the root filesystem, if the existing
genimage.cfg specifies a partition-type-uuid that doesn't match the
one that "L" would imply. In this case, we will keep things as-is to
not break existing setups. However, for all future genimage.cfg files,
we recommend to use "L" for the root filesystem.

The support for this architecture has been removed from the upstream
Linux kernel, as of commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=aec499c75cf8e0b599be4d559e6922b613085f8f
Which states:
The nds32 architecture, also known as AndeStar V3, is a custom
32-bit RISC target designed by Andes Technologies. Support was added
to the kernel in 2016 as the replacement RISC-V based V5 processors
were already announced, and maintained by (current or former) Andes
employees.
As explained by Alan Kao, new customers are now all using RISC-V,
and all known nds32 users are already on longterm stable kernels
provided by Andes, with no development work going into mainline
support any more.
There has also been little to no maintenance done in Buildroot for
this architecture in recent times, so let's follow the Linux kernel
community decision and drop support for this CPU architecture.

With the change of the range of UIDs that is generated from the
automatic ID (-1), it became apparent that there is a potential problem
with these automatic IDs when upgrading: they may have changed, which
means that persistent files that exist outside of the rootfs suddenly
have a different owner.
Add a caveat section to the manual, as well as an explanation of how to
work around the problem.

Some packages have their rust sources as a sub-directory, rather
than at the root of the source tree.
Do like we do for autotools-package, and use the package's _SRCDIR
rather than the top-level directory $(@D).
Additionally, in such a situation, it is more than probable that
the Cargo.toml is also present in that sub-directory, so use that
when vendoring the package.

to this project as well but their Git repo's README includes the
following paragraph:

Remove override of FOO_{CONF_OPTS,DEPENDENCIES} in conditional

The doc-asciidoc infra allows document to define sources and resources,
and those can only be local (there is no download support for documents).
The currently documented way to specify those is to use the $(pkgdir)
macro to point to the document sources and resources when they are along
the .mk.
However, this works only for sources and not for resources.
Indeed, sources are used to generate Makefile dependency rules, so
$(pkgdir) is expanded and evaluated during the call to $(doc-asciidoc),
while resources are expanded and evaluated when the rules are executed,
which always happen after all the parsing has be done, at which point
$(pkgdir) expands to the last Makefile that was parsed, which is always
Buildroot's own manual.
This went unnoticed so far because Buildroot's manual is 1) the last to
be parsed, and 2) not using $(pkgdir) anyway.
Additionally, $(pkgdir) is mostly an internal macro, that is, as this
change demonstrates, difficult to use, and thus should not be used, in
packages or in documents.
We fix that by introducing $(FOO_DOCDIR), similar to $(FOO_PKGDIR),
which points to the document directory. We choose not to name the
variable FOO_PKGDIR, because it semantically is not a package.
As a consequence, the last argument to the doc-asciidoc macro is now
superfluous, so it is removed, which causes a little bit of churn in
the main macro. As a further consequence, the third argument in the
inner macro is no longer needed either, so it too is removed, which
causes a bit more churn yet in the inner macro.

Some software decides based on uid/gid whether a user is a system or
normal (human) user, with different behaviour for those flavors (example
journald [2]).
So adding logic to create system-users is necessary, we take the now
common ranges from [1].
This extends the mkusers script to allow -2 for uid/gid, this argument
will take an identifier from the user range. All identifiers used up to
now should have been from the system range, so -1 is now interpreted as
a system user/group.
Note that after this commit, all the UIDs and GIDs that are created
automatically (with -1) will change. That means if there is peristent
data on an existing system that was created by such an automatic user,
it will suddenly belong to a different user. However, this could already
happen before: if a USERS line is added to a package, then other UIDs
may change as well.
Add system/user ranges as variables, and the argument for user/system
uid variable as well. Thus some magic constants could be removed, some
further occurences of -1 were replaced with equivalent logic. For
consistency, the existing MIN/MAX_UID/GID variables are renamed to
FIRST/LAST_USER_UID/GID.
Update the documentation with the new automatic ranges.

Also, the Config.in example in the manual suggests to use this coding

Use the correct coding style in the chapter "Choosing depends on or select"
