# Host target configuration
# ===========================
common:k_host --config=k_common
common:k_host --platforms=//pw_kernel/target/host:host

# TODO: davidroth - Each config also sets the platform.  This isn't strictly
# necessary when building system images as it will transition to the correct
# platform. This would however break the rust_analyzer gen_rust_project flow
# as it currently assumes the platform is associated with the config.
# In the future we should update the tooling to not require a platform and
# potentially even a config to be set when building the system image.
