Ioannis Glaropoulos 95e8cd0041 soc: arm: nordic_nrf: remove custom fixed MPU region definition
We remove the custom fixed MPU region definition from Nordic
nRF SoC definition, as the common fixed MPU region definition
is now used.

Stephanos Ioannidis 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.

Andrew Fernandes e96673dca7 drivers: spi: nrfx: allow enabling DMA with the nRF52832 despite PAN 58
Add a Kconfig option to enable DMA for SPI with SOC_NRF52832 as long as
it being disabled due to Product Anomaly Notice (PAN) 58 is explicitly
overridden. This allows the SPIM driver to be enabled for the nRF52832
SoC for situations where PAN 58 is not a problem.

Anas Nashif 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.

Piotr Zięcik fdb62f7565 power: Make power_state enum global
Currently each SoC has to define own list of power states.
However all these definitions have to be the same, as common power
management code uses them.

This commit replaces per-soc power state list by global definition.

Sebastian Bøe c4266a8cd2 cmake: Move MDK-defines from 'soc' to the MDK build script
The build script ext/hal/nordic/CMakeLists.txt manages the MDK
dependency. The MDK is not aware of Zephyr and uses it's own defines
to indicate what HW we are building for.

This commit moves these MDK-specific defines out of the 'soc' build
scripts and into the MDK build script where they belong.

This is expected to be a pure refactoring without side-effects.

Piotr Zięcik 9331064ff9 arch: nrf52: Remove ARM_MPU_NRF52X option.
The ARM_MPU_NRF52X option is just selecting ARM_MPU option,
which could be also controlled through menuconfig.

This commit removes the ARM_MPU_NRF52X option and replaces
its usage by ARM_MPU option.
