#
# This file contains the functions needed to setup a target.
# The main function is 'generate_target' which will go over all
# activated modules (symlinks found under core/targets/<target> or
# overlay/targets/<target>) and run the module-specific 'fetch_source',
# 'build' and 'post_copy' functions of the modules.
#
# The functions defined here are module-independent, meaning they
# can process any module, as long as following requirements are met:
#
# - Modules need to have a build-script and a config file,
# i.e. core/module/kernel/module.build
# and core/module/kernel/module.conf
# as these will be read by 'process_module'.
#
# - Modules do not change anything inside the module dirs anymore,
# everything (triggerfiles, source download, build) is done in
# tmp/work/<MODULE>
#
# - Several information have to be set in the config file of
# a module:
# * REQUIRED_BINARIES - list of binaries
# * REQUIRED_FILES - list of regular files
# * REQUIRED_DIRECTORIES - list of directories
# * REQUIRED_SYSTEM_FILES - files to be copied directly from the system
# * REQUIRED_INSTALLED_PACKAGES - list of packages needed at build-time
# * REQUIRED_CONTENT_PACKAGES - list of packages where the contents are to be copied
# * (optional variables needed by the module-build-script)
#
# NOTE: REQUIRED_BINARIES, REQUIRED_FILES, REQUIRED_FILES will be ONLY looked
# for in the module's own build directory!
#
# Optionally, a module can have a static data directory under
# core/modules/<module>/data which will be copied as is to the target build directory.
#
# Moreover modules do not need to specify the dynamic dependencies of given binaries
# as these will be determined automaticly by the helper function 'get_dynamic_dependencies'
