license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

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.

kernel: activate arch interface headers Duplicate definitions elsewhere have been removed. A couple functions which are defined by the arch interface to be non-inline, but were implemented inline by native_posix and intel64, have been moved to non-inline. Some missing conditional compilation for z_arch_irq_offload() has been fixed, as this is an optional feature. Some massaging of native_posix headers to get everything in the right scope.

arch: arm: Move ARM code to AArch32 sub-directory Before introducing the code for ARM64 (AArch64) we need to relocate the current ARM code to a new AArch32 sub-directory. For now we can assume that no code is shared between ARM and ARM64. There are no functional changes. The code is moved to the new location and the file paths are fixed to reflect this change.

nios2: basic build, non-functional Basic build framework for Nios2. Everything is stubbed out, we just want to have a build going so that we can start to parallelize implementation tasks. This patch is not intended to be functional, but should be able to produce a binary for all the nanokernel-based sanity checks.

riscv32: rename to riscv With the upcoming riscv64 support, it is best to use "riscv" as the subdirectory name and common symbols as riscv32 and riscv64 support code is almost identical. Then later decide whether 32-bit or 64-bit compilation is wanted. Redirects for the web documentation are also included. Then zephyrbot complained about this: " New files added that are not covered in CODEOWNERS: dts/riscv/microsemi-miv.dtsi dts/riscv/riscv32-fe310.dtsi Please add one or more entries in the CODEOWNERS file to cover those files " So I assigned them to those who created them.

arch: Add SPARC processor architecture SPARC is an open and royalty free processor architecture. This commit provides SPARC architecture support to Zephyr. It is compatible with the SPARC V8 specification and the SPARC ABI and is independent of processor implementation. Functionality specific to SPRAC processor implementations should go in soc/sparc. One example is the LEON3 SOC which is part of this patch set. The architecture port is fully SPARC ABI compatible, including trap handlers and interrupt context. Number of implemented register windows can be configured. Some SPARC V8 processors borrow the CASA (compare-and-swap) atomic instructions from SPARC V9. An option has been defined in the architecture port to forward the corresponding code-generation option to the compiler. Stack size related config options have been defined in sparc/Kconfig to match the SPARC ABI.
