kernel/arch: consolidate tTCS and TNANO definitions There was a lot of duplication between architectures for the definition of threads and the "nanokernel" guts. These have been consolidated. Now, a common file kernel/unified/include/kernel_structs.h holds the common definitions. Architectures provide two files to complement it: kernel_arch_data.h and kernel_arch_func.h. The first one contains at least the struct _thread_arch and struct _kernel_arch data structures, as well as the struct _callee_saved and struct _caller_saved register layouts. The second file contains anything that needs what is provided by the common stuff in kernel_structs.h. Those two files are only meant to be included in kernel_structs.h in very specific locations. The thread data structure has been separated into three major parts: common struct _thread_base and struct k_thread, and arch-specific struct _thread_arch. The first and third ones are included in the second. The struct s_NANO data structure has been split into two: common struct _kernel and arch-specific struct _kernel_arch. The latter is included in the former. Offsets files have also changed: nano_offsets.h has been renamed kernel_offsets.h and is still included by the arch-specific offsets.c. Also, since the thread and kernel data structures are now made of sub-structures, offsets have to be added to make up the full offset. Some of these additions have been consolidated in shorter symbols, available from kernel/unified/include/offsets_short.h, which includes an arch-specific offsets_arch_short.h. Most of the code include offsets_short.h now instead of offsets.h. Change-Id: I084645cb7e6db8db69aeaaf162963fe157045d5a Signed-off-by: Benjamin Walsh <benjamin.walsh@windriver.com>

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.

Introduce new sized integer typedefs This is a start to move away from the C99 {u}int{8,16,32,64}_t types to Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr to define the sized types in a consistent manor across all the architectures we support and not conflict with what various compilers and libc might do with regards to the C99 types. We introduce <zephyr/types.h> as part of this and have it include <stdint.h> for now until we transition all the code away from the C99 types. We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some existing variables defined u8 & u16 as well as to be consistent with Zephyr naming conventions.

arc: rearrange for standard use of extern "C" Consistently place C++ use of extern "C" after all include directives, within the negative branch of _ASMLANGUAGE if used. Remove extern "C" support from files that don't declare objects or functions. In arch/arc/arch.h the extern "C" in the including context is left active during an include to avoid more complex restructuring. Background from issue #17997: Declarations that use C linkage should be placed within extern "C" so the language linkage is correct when the header is included by a C++ compiler. Similarly #include directives should be outside the extern "C" to ensure the language-specific default linkage is applied to any declarations provided by the included header.

kernel/arch: consolidate tTCS and TNANO definitions There was a lot of duplication between architectures for the definition of threads and the "nanokernel" guts. These have been consolidated. Now, a common file kernel/unified/include/kernel_structs.h holds the common definitions. Architectures provide two files to complement it: kernel_arch_data.h and kernel_arch_func.h. The first one contains at least the struct _thread_arch and struct _kernel_arch data structures, as well as the struct _callee_saved and struct _caller_saved register layouts. The second file contains anything that needs what is provided by the common stuff in kernel_structs.h. Those two files are only meant to be included in kernel_structs.h in very specific locations. The thread data structure has been separated into three major parts: common struct _thread_base and struct k_thread, and arch-specific struct _thread_arch. The first and third ones are included in the second. The struct s_NANO data structure has been split into two: common struct _kernel and arch-specific struct _kernel_arch. The latter is included in the former. Offsets files have also changed: nano_offsets.h has been renamed kernel_offsets.h and is still included by the arch-specific offsets.c. Also, since the thread and kernel data structures are now made of sub-structures, offsets have to be added to make up the full offset. Some of these additions have been consolidated in shorter symbols, available from kernel/unified/include/offsets_short.h, which includes an arch-specific offsets_arch_short.h.

arch: arc: Add the support of secure mode for em In ARC's SecureShield, a new secure mode (currently only em) is added. The secure/normal mode is orthogonal to kernel/user mode. The differences between secure mode and normal mode are following: * different irq stack frame. so need to change the definition of _irq_stack_frame, assembly code. * new aux regs, e.g, secure status(SEC_STAT), secure vector base (VECT_BASE_S) * interrupts and exceptions, secure mode has its own vector base; interrupt can be configured as secure or normal through the interrupt priority aux reg. * secure timers. Two secure timers (secure timer 0 and timer 1) are added.Here, for simplicity and backwards compatibility original internal timers (timer 0 and timer1) are used as sys clock of zephyr * on reset, the processor is in secure mode and secure vector base is used. Note: the mix of secure and normal mode is not supported, i.e. it's assumed that the processor is always in secure mode. Signed-off-by: Wayne Ren <wei.ren@synopsys.com>

kernel/arch: consolidate tTCS and TNANO definitions There was a lot of duplication between architectures for the definition of threads and the "nanokernel" guts. These have been consolidated. Now, a common file kernel/unified/include/kernel_structs.h holds the common definitions. Architectures provide two files to complement it: kernel_arch_data.h and kernel_arch_func.h. The first one contains at least the struct _thread_arch and struct _kernel_arch data structures, as well as the struct _callee_saved and struct _caller_saved register layouts. The second file contains anything that needs what is provided by the common stuff in kernel_structs.h. Those two files are only meant to be included in kernel_structs.h in very specific locations. The thread data structure has been separated into three major parts: common struct _thread_base and struct k_thread, and arch-specific struct _thread_arch. The first and third ones are included in the second. The struct s_NANO data structure has been split into two: common struct _kernel and arch-specific struct _kernel_arch. The latter is included in the former. Offsets files have also changed: nano_offsets.h has been renamed kernel_offsets.h and is still included by the arch-specific offsets.c. Also, since the thread and kernel data structures are now made of sub-structures, offsets have to be added to make up the full offset. Some of these additions have been consolidated in shorter symbols, available from kernel/unified/include/offsets_short.h, which includes an arch-specific offsets_arch_short.h.

arc: rearrange for standard use of extern "C" Consistently place C++ use of extern "C" after all include directives, within the negative branch of _ASMLANGUAGE if used. Remove extern "C" support from files that don't declare objects or functions. In arch/arc/arch.h the extern "C" in the including context is left active during an include to avoid more complex restructuring. Background from issue #17997: Declarations that use C linkage should be placed within extern "C" so the language linkage is correct when the header is included by a C++ compiler. Similarly #include directives should be outside the extern "C" to ensure the language-specific default linkage is applied to any declarations provided by the included header.
