92c12d1f82 toolchain: add GEN_ABSOLUTE_SYM_KCONFIG()
This adds a new GEN_ABSOLUTE_SYM_KCONFIG() specifically for
generating absolute symbols in assembly for kconfig values.
This is needed as the existing GEN_ABSOLUTE_SYM() with
constraints in extended assembly parses the "value" as
signed 32-bit integers. An unsigned 32-bit integer with
MSB set results in a negative number in the final binary.
This also prevents integers larger than 32-bit. So this
new macro simply puts the value inline within the assembly
instrcution instead of having it as parameter.

Fixes #31562

3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier
Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier.  Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.

By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

970758408b printk: don't print incorrect 64-bit integers
printk is supposed to be very lean, but should at least not
print garbage values. Now when a 64-bit integral value is
passed in to be printed, 'ERR' will be reported if it doesn't
fit in 32-bits instead of truncating it.

The printk documentation was slightly out of date, this has been
updated.

Fixes: #7179

923e1b60e7 misc/printk: Make the default char_out routine weak
Architecture init code and/or HAL layers often have a working
"putchar" routine available long before the Zephyr driver layer is
initialized.

Make the default printk() output a weak symbol, so it can be
overridden on these platforms.

Also remove the kconfig depedency on CONSOLE_HAS_DRIVER, as this is a
non-driver mechanism.

8cf8db3a73 Kconfig: Use a short, consistent style for prompts
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
of the rarer variations had to be converted manually.

ec3eff57e0 Kconfig: Use the first default with a satisfied condition
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.

d1684a83a4 Kconfig: Clean up some symbol definitions
- Remove redundant 'n' defaults. 'n' is the default value for bool
  symbols.

  This makes the auto-generated documentation clearer as well: You get
  "implicitly defaults to n" instead of
  "- n if <propagated dependencies>".

- Shorten

      <type>
      prompt "foo"

  to

      <type> "foo"

  This works for all types, not just bool.

- Various formatting nits.

e67720bbf2 syscalls: Scan multiple folders to build complete syscall list
Previously the syscall list was generated only from the include
folder. This is a limitation when the application tries to create
system calls. This patch create a simple way to include these
new syscalls without the application touching the kernel.

This can be enabled by a Kconfig CONFIG_APPLICATION_DEFINED_SYSCALL.
Once enabled the application source directory will be scanned to
find all application defined syscalls.
