Introduction of board and SoC scheme v2. #50305

Hw model v2 scheme offers SoC and maintainers the possibility to define promptless SoCs settings which must be selected by the board Kconfig. Having a board doing `select SOC_<name>` is a much cleaner approach then selecting the SoC in a configuration file. It furthermore removes the need to present all SoCs in choice groups, as the SoC is now an internal setting to Kconfig. This further has the benefit of not presenting users, especially new-comers to Zephyr, with SoC selection options in menuconfig which has potential to cause confusion. It moves the SOC, SOC_SERIES, and SOC_FAMILY from arch/Kconfig into the soc Kconfig tree, where they rightfully belongs. With hw model v2, BOARD name is now passed from the build system to Kconfig which ensures that the board name used in CMake is always in sync with the board name used in Kconfig for hw model v2.

…SoCs The list_hardware.py script parses archs.yml in all <arch-root>/arch folders and soc.yml in all <soc-root>/soc sub-folders. The archs.yml and soc.yml are introduced with hw model v2. Hw model v2 removes the need for architecture knowledge of the SoCs, and as part of this makes multi-arch and multi-core SoCs possible. Hw model v2 also allows for greater flexibility in arch and SoC organization as they can be organized freely. As example SoCs can be organized by vendors, architecture, or any other way as the socs.yml contains the path to the location of the SoC, instead of relying on a specific arch.

Existing Zephyr architectures are already self-contained and thereby HWMv2 compliant. Add all existing architectures to archs.yml. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>

Introduce dedicated arch and soc hw model v2 CMake module files. Rename existing arch and soc cmake file to have a `_v1` post fix. This help to identify the purpose of each of those files and thus a cleaner implementation. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>

Extend list_boards.py and update boards CMake module to handle HWMv2. list_boards.py is extended to support board.yml file in each board folder with various information related to the board, such as vendor, soc, cpucluster, variants, revisions. The HWMv2 removes the requirement for a _defconfig file. It also unifies how board revisions, cpusets, etc is defined which again provides an option for cleaner build system implementation for handling of boards and their integration to the build system. The CMake boards.cmake module is updated to take advantage of the improved design. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>

This commit updates twister testplan.py to handle HWMv2 boards. It does so by switching to use list_boards.py to obtain a list of folders containing <board>.yaml files for processing instead of a global globbing of sub-folders under boards. With HWMv2, boards can be organized more freely, meaning that a fixed glob hierarchy is no longer safe. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>

This commit extends compliance check to include a KconfigBoardV2 check. This check verifies that a v2 scheme board / SoC does not contain references outside the Kconfig trees. The check is invoked as: `check_compliance.py -m KconfigBoardV2` Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>

This commit introduces support for Zephyr hw model v2 in the arch Kconfig tree. The hw model v2 requires Kconfig trees to be self-contained, meaning that the have no Kconfig references outside the tree itself. For hw model v2, the architecture of a board / SoC is not known until the Kconfig tree and config file has been parsed. There provide a new arch/Kconfig.v2 file to support loading of all arch Kconfigs. Hw model v1 is now placed in arch/Kconfig.v1 and includes only the arch Kconfig files determined by the arch of the board. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>

This commit updates arm mps3 an547 board to use HWMv2. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>

This commit updates testcase.yaml and sample.yaml to use mps3/an547 identifier which replaces former mps3_an547 board name. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>
