CONFIG_DEBUG_CREDENTIALS
kernel upstream already removed the CONFIG_DEBUG_CREDENTIALS[1],
this causes do_kernel_configcheck report warnings:
[INFO]: the following symbols were not found in the active configuration:
- CONFIG_DEBUG_CREDENTIALS
[1] https://git.kernel.org/linus/ae191417
Kernel's 6.7+ need this change.

This patch removes the warning message when enabling debug-info.scc:
WARNING: linux-yocto-${PV} do_kernel_configcheck: \
[kernel config]: This BSP contains fragments with warnings:
[INFO]: the following symbols were not found in the active configuration:
- CONFIG_TEST
CONFIG_TEST is not a real config and is apparently an artifact from an
old test.

Upstream is dropping support for is not set, so we adjust our
configs accordingly.
Commit:
https://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git/commit/?h=for-next&id=55de8686df7ed2b5237867b130e30c728bbd9db4
kconfig: change .config format to use =n instead of "is not set"
The .config file uses "# CONFIG_FOO is not set" form to represent
disabled options. In the old days, it was useful because the .config
was directly included from Makefiles. For example, you can use
"ifdef CONFIG_FOO" in Makefiles to check if the option is enabled.
Commit c955ccafc38e ("kconfig: fix .config dependencies") introduced
include/config/auto.conf, which mirrors the .config, but trims down
all disabled options.
Since then, include/config/auto.conf defines CONFIG options during the
build. The .config is used just for storing the user's configuration.
I do not see a strong reason to use a particular pattern of comment
for disabled options.
With this commit, Kconfig will output disable options in a more natural
form, "CONFIG_FOO=n".
Kconfig accepts both "# CONFIG_FOO is not set" and "CONFIG_FOO=n" as a
valid input. You do not need to update arch/*/configs/*_defconfig files
for now. "git bisect" should be able to cross the commit in both ways
without any issue.
A problem may occur if you parse the .config for the "# ... is not set"
patterns.
I adjusted streamline_config.pl, merge_config.sh,
scripts/kconfig/tests/.

Add a scc file that groups together various debug and emulation features needed
for syzkaller fuzzing. Syzkaller runtime sanity checks now report that most
required features are enabled:
loading corpus...
serving http on http://127.0.0.1:53725
serving rpc on tcp://[::]:39765
booting test machines...
wait for the connection from test machine...

Add support for enabling fault injection debugfs capabilities. It's desirable
to have this feature enabled when doing kernel fuzzing with syzkaller.

KCOV exposes kernel code coverage information in a form suitable for
coverage-guided fuzzing. This debug feature can be enabled to add support for
kernel fuzzing (with tools such as syzkaller).

Remove CONFIG_OPTIMIZE_INLINING and associated features entirely. The
config has been removed starting 5.7.

commit 69c1f396 [efi/x86: Convert x86 EFI earlyprintk into generic
earlycon implementation] changes the location, implementation and
Kconfig option for EFI early console.
So we update our fragments to match.
