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.

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>

arc: implement stack checking ARC CPU has stack checking feature that allows to trigger an exception whenever the stack is incorrectly accessed. This patch implements the stack_top and stack_base register updates on context switches, and activates the Stack Checking bit of STATUS32 register when the CPU is in the context of a fiber or task. As GCC accesses the non-yet allocated stack with frame pointer enabled, this patch also add the omit-frame-pointer gcc flag in order to work properly.

arc: fix CONFIG_ARC_STACK_CHECKING - There's no clear need to disable frame pointers if this feature is used, remove this directive. - The 'top' and 'base' terms are reversed. The 'base' is the high address of the stack. The top is the lowest address, where we cannot push further down. Fixup member and offset names to correspond to how these terms are used in hardware documentation. - Use correct pointers for stack top location - Fatal exceptions now go through _NanoFatalErrorHandler to report the faulting ip and thread.

arch: arc: add user space support for arc * add the implementation of syscall * based on 'trap_s' intruction, id = 3 * add the privilege stack * the privilege stack is allocted with thread stack * for the kernel thread, the privilege stack is also a part of thread stack, the start of stack can be configured as stack guard * for the user thread, no stack guard, when the user stack is overflow, it will fall into kernel memory area which requires kernel privilege, privilege violation will be raised * modify the linker template and add MPU_ADDR_ALIGN * add user space corresponding codes in mpu * the user sp aux reg will be part of thread context * When user thread is interruptted for the 1st time, the context is saved in user stack (U bit of IRQ_CTLR is set to 1). When nest interrupt comes, the context is saved in thread's privilege stack * the arc_mpu_regions.c is moved to board folder, as it's board specific * the above codes have been tested through tests/kernel/mem_protect/ userspace for MPU version 2 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. 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>

boards: Update arc em_starterkit support from 2.2 to 2.3 Here are the main changes: * board: Update EMSK onboard resources such as Button, Switch and LEDs + update soc.h for em7d, em9d, em11d + update board.h for em_starterkit board * arc: Add floating point support and code density support + add kconfig configuration + add compiler options + add register definitions, marcos, assembly codes + fixes in existing codes and configurations. * arc: Update detailed board configurations for cores of emsk 2.3 * script: Provide arc_debugger.sh for debugging em_starterkit board + make BOARD=em_starterkit debug This will start openocd server for emsk, and arc gdb will connect to this debug server, user can run `continue` command if user just want to run the application, or other commands if debugging needed. + make BOARD=em_starterkit debugserver This will start an openocd debugger server for emsk, and user can connect to this debugserver using arc gdb and do what they want to. + make BOARD=em_starterkit flash This will download the zephyr application elf file to emsk, and run it.
