I removed GPIO configuration from board files and enabled them
as default in driver Kconfig file. All boards had GPIO ports
enabled that is why I decided to enable it by default.

There exist two symbols that became equivalent when PR #9383 was
merged; _SYSCALL_LIMIT and K_SYSCALL_LIMIT. This patch deprecates the
redundant _SYSCALL_LIMIT symbol.
_SYSCALL_LIMIT was initally introduced because before PR #9383 was
merged K_SYSCALL_LIMIT was an enum, which couldn't be included into
assembly files. PR #9383 converted it into a define, which can be
included into assembly files, making _SYSCALL_LIMIT redundant.
Likewise for _SYSCALL_BAD.

Consistently use
config FOO
bool/int/hex/string "Prompt text"
instead of
config FOO
bool/int/hex/string
prompt "Prompt text"
(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.
Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some

A design flaw of 'gsource' is that there's no way to require at least
one file to match the glob pattern. This could lead to silent errors.
Switch to a new design, where a plain 'source' is globbing and requires
at least one file to match. A separate 'osource' (optional source)
statement is available for cases where it's okay for a pattern (or plain
filename) to not match any files.
'orsource' combines 'osource' and 'rsource' (relative source).
This commit search-replaces 'gsource' with 'source', but backwards
compatibility with 'gsource' is still maintained by making it an alias
for 'osource' (and by making 'grsource' an alias for 'orsource').
The three Kconfig files arch/{nios2,posix,xtensa}/Kconfig source
arch/{nios2,posix,xtensa}/soc/*/Kconfig, which doesn't match any files.
Use 'osource' for those. The soc/*/Kconfig files seem to be for
additional SoC-specific symbols, only none exist yet on those ARCHes.
Also use 'osource' for the source of $ENV_VAR_BOARD_DIR/Kconfig in
boards/Kconfig, which doesn't exist for all boards.

Up until now, Zephyr has patched Kconfig to use the last 'default' with
a satisfied condition, instead of the first one. I'm not sure why the
patch was added (it predates Kconfiglib), but I suspect it's related to
Kconfig.defconfig files.
There are at least three problems with the patch:
1. It's inconsistent with how Kconfig works in other projects, which
might confuse newcomers.
2. Due to oversights, earlier 'range' properties are still preferred,
as well as earlier 'default' properties on choices.
In addition to being inconsistent, this makes it impossible to
override 'range' properties and choice 'default' properties if the
base definition of the symbol/choice already has 'range'/'default'
properties.
I've seen errors caused by the inconsistency, and I suspect there
are more.
3. A fork of Kconfiglib that adds the patch needs to be maintained.
Get rid of the patch and go back to standard Kconfig behavior, as
follows:
1. Include the Kconfig.defconfig files first instead of last in
Kconfig.zephyr.
2. Include boards/Kconfig and arch/<arch>/Kconfig first instead of
last in arch/Kconfig.
3. Include arch/<arch>/soc/*/Kconfig first instead of last in
arch/<arch>/Kconfig.
4. Swap a few other 'source's to preserve behavior for some scattered
symbols with multiple definitions.
Swap 'source's in some no-op cases too, where it might match the
intent.
5. Reverse the defaults on symbol definitions that have more than one
default.
Skip defaults that are mutually exclusive, e.g. where each default
has an 'if <some board>' condition. They are already safe.
6. Remove the prefer-later-defaults patch from Kconfiglib.
Testing was done with a Python script that lists all Kconfig
symbols/choices with multiple defaults, along with a whitelist of fixed
symbols. The script also verifies that there are no "unreachable"
defaults hidden by defaults without conditions
As an additional test, zephyr/.config was generated before and after the
change for several samples and checked to be identical (after sorting).
This commit includes some default-related cleanups as well:
- Simplify some symbol definitions, e.g. where a default has 'if FOO'
when the symbol already has 'depends on FOO'.
- Remove some redundant 'default ""' for string symbols. This is the
implicit default.
Piggyback fixes for swapped ranges on BT_L2CAP_RX_MTU and
BT_L2CAP_TX_MTU (caused by confusing inconsistency).
Piggyback some fixes for style nits too, e.g. unindented help texts.

This patch adds the RDC (Resource Domain Controller) peripheral
permissions settings for the i.MX applications cores (Cortex A9 on
i.MX6 and Cortex A7 on i.MX7).
This will enable both Linux (on application's core) and Zephyr (on M4
core) to share the peripherals and coexist.
The settings are defined at devicetree level and applied in the soc.c.
A complete solution should involve the SEMA4 to control the peripherals
access and prevent resource deadlocking and misusage.

symbols.
This makes the auto-generated documentation clearer as well: You get

to

This works for all types, not just bool.
