Currently, our bundled kconfig copy does not require that a base
configuration file, with some non-default set in there, be specified
for defconfig, and we only pass one if specified by the user.
Future kconfig versions will require a base config file be always
specified, so prepare for that: if the user did not specify a base
config file, use /dev/null, an empty file, to specify there is no
preset value.

All file paths in patch 23-kconfig-mn-conf-handle-backspace-H-key.patch
have a leading "kconfig/" prefix, unlike all the other kconfig patches.
Therefore, it does not apply or unapply cleanly.
Let's therefore remove that prefix so this patch can be applied along all
its siblings.

Hu? What is this thing?
And what about the other packages that are like openssl, i.e virtual
packages that may have providers in BR2_EXTERNAL trees?
Thanks!

Not exactly sure for this particular entry (maybe you still remember
that part @Peter Seiderer ?). Indeed, if I revert that particular change
everything still works as expected. However, reverting either the
libressl or libopenssl trigger the issue.
What I can tell for sure is that the libressl & libopenssl changes are
required because a choice can no longer contain ifs, and the included
file have some; hence the trickery to move them out of the choice.
I don't know about a publicly available br2-external that provides
openssl, but if you have some I'd be glad to look further into that.

To the extent of my understanding, this is because the included files do
not contain ifs ? At least it is the easier case, as we don't have any
external at the moment.
So maybe we should do it for all places where we include an external as
a preventive measure, in case the external provided config.in contains
any if condition.

Thanks you for looking into this !

I don't have one, but it should be trivial to create a fake/dummy one,
to make sure this continues to work. Or maybe we have a runtime test
for this? (And if not we should have one!)

Since the update of kconfig, $VARIABLES are no longer expanded.
Update the Buildoot user manual accordingly.

As informally proposed during the 2026 Buildroot dev meeting,
this introduces a new kconfig user interface based on Zephyr's kconfiglib.
The name "yellowconfig" is inspired by the yellow-themed curses interface,
as opposed to the classical blue "menuconfig".
Read more about kconfiglib: https://github.com/zephyrproject-rtos/Kconfiglib
To run that target, one has to install kconfiglib beforehand,
for example by issuing the following command:
> pip install kconfiglib
In terms of user interface differences, Zephyr's kconfig brings:
- searching symbols as you type, and more symbols are visible in a single
page of search results [1]
- symbols that aren't selectable (because of unmet dependencies) can be
viewed (toggling them on or off with the key "A") [2]
- symbols y/n dependencies are displayed more clearly, each one on a newline.
This is especially appreciable when there are many of them, whereas in the
classical menuconfig one has to scroll left/right to view them [3]
Having this as a new make target allow for Buildroot users to try it out
and forge their opinion on this different interface without breaking
habits and usual workflows. However, in the longer run, this could possibly
allow to replace the custom-patched kconfig programs we ship in Buildroot
with an unmodified upstream supported codebase.
Moreover, as unselectable symbols can be displayed in the interface, this
would remove the need for comments in the like "<pkg> needs <condition>",
where we need to invert and maintain conditional dependencies.
As a final nice addition, having a Python based kconfiglib allows for
programmatic access to kconfig symbols and settings in scripts, which
could be useful in testing scenarios.
