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>

# SPDX-License-Identifier: Apache-2.0
Use SoC instead of platform. Change terminology and use SoC instead of platform. An SoC provides features and default configurations available with an SoC. A board implements the SoC and adds more features and IP block specific to the board to extend the SoC functionality such as sensors and debugging features.

kconfig: Remove assignments to CONFIG_<arch> syms and hide them All board defconfig files currently set the architecture in addition to the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up defconfig files. CONFIG_<arch> symbols currently being set in configuration files also means that they are configurable (can be changed in menuconfig and in configuration files), even though changing the architecture won't work, since other things get set from -DBOARD=<board>. Many boards also allow changing the architecture symbols independently from the SoC symbols, which doesn't make sense. Get rid of all assignments to CONFIG_<arch> symbols and clean up the relationships between symbols and the configuration interface, like this: 1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and turn the CONFIG_<arch> symbols into invisible (promptless/nonconfigurable) symbols instead. Getting rid of the choice allows the symbols to be 'select'ed (choice symbols don't support 'select'). 2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols. This makes sense since you know the architecture if you know the SoC. Put the select on the SOC_* symbol instead for boards that don't have a SOC_SERIES_*. 3. Remove all assignments to CONFIG_<arch> symbols. The assignments would generate errors now, since the symbols are promptless. The change was done by grepping for assignments to CONFIG_<arch> symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the same defconfig file, and putting a 'select' on it instead. See https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed for a split-up version of this commit, which will make it easier to see how stuff was done. This needs to go in as one commit though. This change is safer than it might seem re. outstanding PRs, because any assignment to CONFIG_<arch> symbols generates an error now, making outdated stuff easy to catch.

x86: remove CONFIG_CPU_MINUTEIA Since the removal of Quark-based boards, there are no user of Minute-IA. Also, the generic x86 SoC is not exactly Minute-IA so change it to use a fairly safe CPU_ATOM. Fixes #14442 Signed-off-by: Daniel Leung <daniel.leung@intel.com>

x86: add kconfigs and compiler flags for MMX and SSE* This adds kconfigs and compiler flags to support MMX and SSE* instructions. Signed-off-by: Daniel Leung <daniel.leung@intel.com>

x86: reserve the first megabyte A more comprehensive solution would use E820 enumeration, but we are unlikely to ever care that much, as we intend to use demand paging on microcontrollers and not PC-like hardware. This is really to just prevent QEMU from crashing. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
