# 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:
