# Configure SoC settings based on Kconfig settings.
#
# This CMake module will set the following variables in the build system based
# on Kconfig settings for the selected SoC.
#
# Outcome:
# The following variables will be defined when this CMake module completes:
#
# - SOC_FULL_DIR: Full directory of where the SoC files are located
# - SOC_DIRECTORIES: List of directories where SoC files which include this SoC are located
# - SOC_TOOLCHAIN_NAME: Optional toolchain name of the SoC
#
# Variables set by this module and not mentioned above are considered internal
# use only and may be removed, renamed, or re-purposed without prior notice.
