util/kconfig: Uprev to Linux 5.13's kconfig

Browse Source 
This was originally several commits that had to be squashed into one
because the intermediate states weren't able to build coreboot:

 - one to remove everything that wasn't our own code, leaving only
   regex.[ch], toada.c, description.md and Makefile.inc.
 - one to copy in Linux 5.13's scripts/kconfig and adapt Makefile.inc
   to make the original Makefile work again.
 - adapt abuild to use olddefconfig, simplifying matters.
 - apply patches in util/kconfig/patches.
 - Some more adaptations to the libpayload build system.

The patches are now in util/kconfig/patches/, reverse applying them
should lead to a util/kconfig/ tree that contains exactly the Linux
version + our own 5 files.

- savedefconfig - Creates a ‘defconfig’ file, stripping out all of the symbols
that were left as default values. This is very useful for debugging, and is
how config files should be saved.
- silentoldconfig - This evaluates the .config file the same way that the
oldconfig target does, but does not print out each question as it is
evaluated. It still stops to query the user if an option with no answer in
the .config file is found.

Subject: [PATCH] Kconfig: Add KCONFIG_STRICT mode
This is basically a -Werror mode for Kconfig. When exporting
KCONFIG_STRICT in the Makefile, warnings in Kconfig will produce
errors instead.
This will make it easier to spot unclean Kconfig files, settings
and dependencies.

Subject: [PATCH] Kconfig: Change symbol override from warning to notice
Overriding symbols within a .config is pretty common when doing
automated builds with various different options. The warning
text makes it sound like this is an issue, so change it to say
'notice' instead. We could get rid of it completely, but it's
not a bad thing to know that we have two copies of the same symbol
in the .config.
BUG=chrome-os-partner:54059
TEST=copy a disabled kconfig option to the end and set it to y.
See notice text instead of warning.

Subject: [PATCH] util/kconfig: Ignore extra symbols in configs instead of
failing
When updating an old .config file that has a symbol that has been
removed from the current Kconfig tree, kconfig will generate a warning
and fail to save the updated file. This is incredibly annoying, and
not the goal when trying to eliminate Kconfig warnings.
Instead of generating a warning, just print a message that it's being
ignored. This will remove the offending symbol, while allowing the
updated config file to be saved.
Split the change from 1 line to 3 lines to keep it at 80 characters.

Subject: [PATCH] kconfig: Allow KCONFIG_STRICT outside of confdata.c
To catch dependency errors in symbol.c (such as the ones
fixed by I51b4ee326f082c6a656a813ee5772e9c34f5c343) we need
to check for global kconfig warnings before saving config
files.
This patch will produce errors for wrong dependencies and
add catching of errors to conf, nconf and mconf. Sorry,
gconf users, you will have to wait.

Subject: [PATCH] kconfig: Add wildcard support for "source"
Kconfig's include directive "source" does not support
wildcards (e.g. source src/mainboard/*/Kconfig) which
makes automatic inclusion of all boards a tedious task
and prevents us from implementing "drop in" boards.
In our Makefile.inc files we already include mainboard
directories per wildcard, so let's add the infrastructure
to do the same with Kconfig.
v2: change from wordexp to glob for better portability.

Kconfig: Write tmp files into same directory as target files
This removes the need for COREBOOT_BUILD_DIR in Kconfig. Since the
original files will be replaced with the tmp file, the parent directory
already needs to be writable.
Before this change, the tmp files would be created in the CWD (src) if
COREBOOT_BUILD_DIR was not specified.
BUG=b:112267918
TEST=emerge-grunt coreboot and verified no tmp files were created in the
src directory.

# is perfect for you.
#
# It gives you the ability to turn off all the modules that are
# not loaded on your system.
#
# Howto:
#
# 1. Boot up the kernel that you want to stream line the config on.
# 2. Change directory to the directory holding the source of the
# kernel that you just booted.
# 3. Copy the configuration file to this directory as .config
# 4. Have all your devices that you need modules for connected and
# operational (make sure that their corresponding modules are loaded)
# 5. Run this script redirecting the output to some other file
# like config_strip.
# 6. Back up your old config (if you want too).
# 7. copy the config_strip file to .config
# 8. Run "make oldconfig"
#
# Now your kernel is ready to be built with only the modules that
# are loaded.
#
# Here's what I did with my Debian distribution.
#
# cd /usr/src/linux-2.6.10
# cp /boot/config-2.6.10-1-686-smp .config
# ~/bin/streamline_config > config_strip
# mv .config config_sav
# mv config_strip .config
# make oldconfig
