87e917a925 kconfig: Remove redundant 'default n' and 'prompt' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Also replace some

    config
    	prompt "foo"
    	bool/int

with the more common shorthand

    config
    	bool/int "foo"

2d7460482d headers: Refactor kernel and arch headers.
This commit refactors kernel and arch headers to establish a boundary
between private and public interface headers.

The refactoring strategy used in this commit is detailed in the issue

This commit introduces the following major changes:

1. Establish a clear boundary between private and public headers by
  removing "kernel/include" and "arch/*/include" from the global
  include paths. Ideally, only kernel/ and arch/*/ source files should
  reference the headers in these directories. If these headers must be
  used by a component, these include paths shall be manually added to
  the CMakeLists.txt file of the component. This is intended to
  discourage applications from including private kernel and arch
  headers either knowingly and unknowingly.

  - kernel/include/ (PRIVATE)
    This directory contains the private headers that provide private
   kernel definitions which should not be visible outside the kernel
   and arch source code. All public kernel definitions must be added
   to an appropriate header located under include/.

  - arch/*/include/ (PRIVATE)
    This directory contains the private headers that provide private
   architecture-specific definitions which should not be visible
   outside the arch and kernel source code. All public architecture-
   specific definitions must be added to an appropriate header located
   under include/arch/*/.

  - include/ AND include/sys/ (PUBLIC)
    This directory contains the public headers that provide public
   kernel definitions which can be referenced by both kernel and
   application code.

  - include/arch/*/ (PUBLIC)
    This directory contains the public headers that provide public
   architecture-specific definitions which can be referenced by both
   kernel and application code.

2. Split arch_interface.h into "kernel-to-arch interface" and "public
  arch interface" divisions.

  - kernel/include/kernel_arch_interface.h
    * provides private "kernel-to-arch interface" definition.
    * includes arch/*/include/kernel_arch_func.h to ensure that the
     interface function implementations are always available.
    * includes sys/arch_interface.h so that public arch interface
     definitions are automatically included when including this file.

  - arch/*/include/kernel_arch_func.h
    * provides architecture-specific "kernel-to-arch interface"
     implementation.
    * only the functions that will be used in kernel and arch source
     files are defined here.

  - include/sys/arch_interface.h
    * provides "public arch interface" definition.
    * includes include/arch/arch_inlines.h to ensure that the
     architecture-specific public inline interface function
     implementations are always available.

  - include/arch/arch_inlines.h
    * includes architecture-specific arch_inlines.h in
     include/arch/*/arch_inline.h.

  - include/arch/*/arch_inline.h
    * provides architecture-specific "public arch interface" inline
     function implementation.
    * supersedes include/sys/arch_inline.h.

3. Refactor kernel and the existing architecture implementations.

  - Remove circular dependency of kernel and arch headers. The
   following general rules should be observed:

    * Never include any private headers from public headers
    * Never include kernel_internal.h in kernel_arch_data.h
    * Always include kernel_arch_data.h from kernel_arch_func.h
    * Never include kernel.h from kernel_struct.h either directly or
     indirectly. Only add the kernel structures that must be referenced
     from public arch headers in this file.

  - Relocate syscall_handler.h to include/ so it can be used in the
   public code. This is necessary because many user-mode public codes
   reference the functions defined in this header.

  - Relocate kernel_arch_thread.h to include/arch/*/thread.h. This is
   necessary to provide architecture-specific thread definition for
   'struct k_thread' in kernel.h.

  - Remove any private header dependencies from public headers using
   the following methods:

    * If dependency is not required, simply omit
    * If dependency is required,
      - Relocate a portion of the required dependencies from the
       private header to an appropriate public header OR
      - Relocate the required private header to make it public.

This commit supersedes #20047, addresses #19666, and fixes #3056.

bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

2b61031c8f kconfig: Remove symbol types from Kconfig.defconfig files
Same deal as in commit 7fdb525754 ("kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), but I hacked Kconfiglib to also
find cases where the type is given separately as e.g.

    config FOO
            int
            default 3

Motivation (from a note in
https://docs.zephyrproject.org/latest/guides/kconfig/index.html):

    For a symbol defined in multiple locations (e.g., in a
    Kconfig.defconfig file in Zephyr), it is best to only give the
    symbol type for the "base" definition of the symbol, and to use
    'default' (instead of 'def_<type>' value) for the remaining
    definitions. That way, if the base definition of the symbol is
    removed, the symbol ends up without a type, which generates a
    warning that points to the other definitions. That makes the extra
    definitions easier to discover and remove.

It's also nice if 'def_bool' and the like turn into a semi-reliable flag
that the symbol is only defined in Kconfig.defconfig files. That might
be a sign that things could be cleaned up.

Will do a separate pass later to remove some symbols only defined in
Kconfig.defconfig files.

ac9fe11f2f Kconfig: Remove copy-pasted comments on some promptless symbols
Remove the

    # Omit prompt to signify a "hidden" option

comments that appear on some symbols. They seem to have been copy-pasted
at random, as there are lots of promptless symbols that don't have them
(that's confusing in itself, because it might give the idea that the
ones with comments are special in some way).

I suspect those comments wouldn't have helped me much if I didn't know
Kconfig either. There's a lot more Kconfig documentation now too, e.g.
https://docs.zephyrproject.org/latest/guides/kconfig/index.html.

Keep some comments that give more information than the symbol having no
prompt.

Also do some minor drive-by cleanup.

7fdb525754 kconfig: Use 'default' instead of 'def_bool' in Kconfig.defconfig files
Same deal as in commit 4638652214 ("Kconfig: Use 'default' instead of

Some symbols, like ALTERA_AVALON_PIO, are only defined in
Kconfig.defconfig files, and so need the def_bool.

Motivation (from the note at the end of

For a symbol defined in multiple locations (e.g., in a Kconfig.defconfig
file in Zephyr), it is best to only give the symbol type for the "base"

value) for the remaining definitions. That way, if the base definition

c5592de5ae uart/ns16550: Give CONFIG_NS16550_REG_SHIFT a DT_* prefix instead
This value always comes from DTS. No Kconfig symbol named
NS16550_REG_SHIFT ever existed.

Might've been missed in commit 603f068690 ("uart/ns16550: Use DT_ prefix
for remaining device configs").

603f068690 uart/ns16550: Use DT_ prefix for remaining device configs
Previous rename from CONFIG_* to DT_* left a few remaining
CONFIG_*. So rename them manually now.

Fix #13753
