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>

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.
