# This CMake module is only valid for hw model v1.
|
|
# In hw model v1, then arch is determined by the board folder structure.
|
|
#
|
|
# Configure ARCH settings based on board directory 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
|
|
# - BOARD_DIR: CMake variable specifying the directory of the selected BOARD
|
|
#
|
|
# 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.
