644f9ecbf0 dts: nordic: introduce wdt0 / wdt1 distinction
Add wdt0 node labels for all watchdogs. Keep the existing wdt node
labels in place for backwards compatibility.

Add a wdt1 node to the nRF5340 application core .dtsi, but leave it
disabled. Leave the wdt node's label set to "WDT" on this core for
backwards compatibility also, in case any users are getting it with a
string literal instead of asking the devicetree. This can be changed
later after this round of watchdog changes has been shaken out and
tested more.

When enabled, instead of erasing entire flash page at once, page will
be erased in defined time slices. Erasing single page stalls CPU
for significant time share (~80ms) and partial erase divides the
operation in to the shorter time periods, resuming CPU operation in

011e9bac0b drivers: nrf: Remove no longer suitable dependencies on Kconfig options
Make I2C and SPI drivers for nRF SoCs no longer dependent on Kconfig
options that enable instances (i.e. I2C_x and SPI_x). Now these drivers
enable hardware instances when corresponding nodes in devicetree are
enabled (have status "okay").
For I2C, SPI, and UART drivers, instead of using Kconfig dependencies
to prevent enabling of hardware instances that cannot be used together
(e.g. SPIM1 and TWIM1), a file that signals invalid configurations with
build assertions is added to compilation.
Also dependencies on HAS_HW_NRF_* options are removed from Kconfigs
of I2C, SPI, and UART drivers, as for hidden options that activate
proper type of driver such dependencies are not actually helpful.

3e93f9f67d modules: hal: nordic: Fix translation of peripheral symbols
Update the hal_nordic module revision, to apply the following changes:

nrfx_config: Fix translation of symbols for _S or _NS only peripherals

For peripherals with only one type of access available (either secure
or non-secure), the common symbol translation scheme cannot be used
as it leads to mapping to non-existing symbols (e.g. NRF_FICR_NS).
Instead, use fixed translations for these symbols (e.g. NRF_FICR to
NRF_FICR_S, only for secure images).

nrfx_config: Add missing _S/_NS symbol translations for nRF5340/nRF9160

Add translations of names with _S and _NS suffixes for peripheral
access symbols that are available for a given chip but were not used
so far in any nrfx HAL or driver, to make the lists of translations
complete and consistent.

This commit corrects also the translation of NRF_I2S symbol for nRF5340
whose name for this SoC contains also the index 0 (so it needs to be
handled similarly like NRF_PDM0 is).

a42a42cd5a kconfig: Replace defconfig singe-symbol 'if's with 'depends on'
Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.

Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.

Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

c5839f834b kconfig: Remove assignments to CONFIG_<arch> syms and hide them
All board defconfig files currently set the architecture in addition to
the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up
defconfig files.

CONFIG_<arch> symbols currently being set in configuration files also
means that they are configurable (can be changed in menuconfig and in
configuration files), even though changing the architecture won't work,
since other things get set from -DBOARD=<board>. Many boards also allow
changing the architecture symbols independently from the SoC symbols,
which doesn't make sense.

Get rid of all assignments to CONFIG_<arch> symbols and clean up the
relationships between symbols and the configuration interface, like
this:

1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and
   turn the CONFIG_<arch> symbols into invisible
   (promptless/nonconfigurable) symbols instead.

   Getting rid of the choice allows the symbols to be 'select'ed (choice
   symbols don't support 'select').

2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols.
   This makes sense since you know the architecture if you know the SoC.

   Put the select on the SOC_* symbol instead for boards that don't have
   a SOC_SERIES_*.

3. Remove all assignments to CONFIG_<arch> symbols. The assignments
   would generate errors now, since the symbols are promptless.

The change was done by grepping for assignments to CONFIG_<arch>
symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the
same defconfig file, and putting a 'select' on it instead.

See
https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed
for a split-up version of this commit, which will make it easier to see
how stuff was done. This needs to go in as one commit though.

This change is safer than it might seem re. outstanding PRs, because any
assignment to CONFIG_<arch> symbols generates an error now, making
outdated stuff easy to catch.

4e85006ba4 dts: Rename generated_dts_board*.{h,conf} to devicetree*.{h,conf}
generated_dts_board.h is pretty redundant and confusing as a name. Call
it devicetree.h instead.

dts.h would be another option, but DTS stands for "devicetree source"
and is the source code format, so it's a bit confusing too.

The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.

with misc. documentation.

hal_ti, mcuboot, and ci-tools updates are included too, in the west.yml

49bd19f3f2 soc: nrf5340: Fix busy waiting on nRF5340 application core
This patch adds a temporary workaround for the incorrect initialization
of the SystemCoreClock global variable that is done for the application
core of nRF5340 (see system_nrf5340_application.c) and that results in
k_busy_wait() producing delays of twice the requested time.
The problem is that the call to SystemCoreClockUpdate() that is done
at the end of SystemInit() correctly sets the value of SystemCoreClock
to reflect the hardware state after reset (HFCLK128M divided by 2),
but then the SystemCoreClock variable is initialized (by z_data_copy()
called from z_arm_prep_c()) to the __SYSTEM_CLOCK value that is defined
as 128000000. This in turn results in nrfx_coredep_delay_us() (used by
k_busy_wait() by default for nRF SoCs) delaying for twice the requested
number of microseconds.
The temporary workaround is to call SystemCoreClockUpdate() at a later
stage of the system initialization, in its nRF53 specific part.

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.

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.)

    git ls-files '*Kconfig*' | \
        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

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.

a02c333963 arm/riscv: kconfig: Remove type from NUM_IRQS in defconfig files
Add a common definition for NUM_IRQS in arch/arm/core/Kconfig and
arch/riscv/Kconfig. That way, the type doesn't have to be given for
NUM_IRQS in all the Kconfig.defconfig files.

Trying to get rid of unnecessary "full" symbol definitions in
Kconfig.defconfig files, to make the organization clearer. It can also
help with finding unused symbols.
