license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

ARC: Add support for ARC HS family of CPU cores The ARC HS is a family of high performance CPUs from Synopsys capable of running wide range of applications from heavy DPS calculation to full-scale OS. Still as with other ARC cores ARC HS might be tailored to a particular application. As opposed to EM cores ARC HS cores always have support of unaligned data access and by default GCC generates such a data layout with so we have to always enable unaligned data access in runtime otherwise on attempt to access such data we'd see "Unaligned memory exception". Note we had to explicitly mention CONFIG_CPU_ARCEM=y in all current defconfigs as CPU_ARC{EM|HS} are now parts of a choice so we cannot simply select ether option in board's Kconfig. And while at it change "-mmpy-option" of ARC EM to "wlh1" which is the same as previously used "6" but matches Programmer's Reference Manual (PRM) and is more human-friendly.

soc: arc: optmize and bug fix the compile options * when -mcpu is given, e.g. -mcpu=em4_dmips,-mnorm,-mdiv_em etc. are already given, no need to duplicate * use zephyr_compiler_options to replace zephyr_cc_option zephyr_cc_option will do compile option check first then add the checked options into option list. It's too strict that makes options like -mfpu, -mmpy-option cannot be added. Signed-off-by: Wayne Ren <wei.ren@synopsys.com>
