# Configure ARCH settings based on KConfig settings and arch root. |
|
# |
|
# This CMake module will set the following variables in the build system based |
|
# on board directory and arch root. |
|
# |
|
# If no implementation is available for the current arch an error will be raised. |
|
# |
|
# Outcome: |
|
# The following variables will be defined when this CMake module completes: |
|
# |
|
# - ARCH: Name of the arch in use. |
|
# - ARCH_DIR: Directory containing the arch implementation. |
|
# - ARCH_ROOT: ARCH_ROOT with ZEPHYR_BASE appended |
|
# |
|
# Variable dependencies: |
|
# - ARCH_ROOT: CMake list of arch roots containing arch implementations |
|
# |
|
# 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. |
