# SCMI server library is built from SCP-firmware source tree.
# The firmware is made of a framework, a product and modules.
# Only modules used by firmware must be built, as stated by
# CFG_SCPFW_MOD_* switches. SCP-firmware needs a C source and
# a header file to be generated to describe embedded modules.
# This is done through cmake configuration of the package.
# The toolchain build directive must also match the list of
# embedded modules.
