Zephyr module and build settings. (BOARD, SOC, DTS, and ARCH root support)
Rasmussen, Torsten
Hi,
Zephyr modules has been extended to support multiple BOARD_ROOT, SOC_ROOT, DTS_ROOT, and ARCH_ROOT on command line. Also Zephyr modules `module.yml` schema has been extended to allow modules to describe those roots as build settings.
For example: build: settings: board_root: . dts_root: . soc_root: . arch_root: .
See more here: https://docs.zephyrproject.org/latest/guides/modules.html#build-settings
As part of this, the `SOC_DIR` in Kconfig files has been removed, and any Kconfig code relying on `SOC_DIR` must be updated, for example to use `rsource`. If your code is currently having a Kconfig in `<my_soc_root>/<arch>/Kconfig` sourcing other files based on `SOC_DIR`:
<my_soc_root>/<arch>/Kconfig: source $(SOC_DIR)/$(ARCH)/Kconfig.soc
then such code can be updated to: rsource Kconfig.soc
