arc: add support for generic Add support for a "generic" ARC implementation. This is a misnomer since ARC platforms are synthesized by the SOC vendor and are specifc to a given vendors implementation/configuration. This platform support if for an SOC where we are allowed to let the code to support the SOC into the wild but not allowed to name it in public. This change allows to work on support for the SOC in the open and let the rest of the community see the evolution of of the platform.

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.

*/
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>
