1# SCMI server library is built from SCP-firmware source tree. 2# The firmware is made of a framework, a product and modules. 3# Only modules used by firmware must be built, as stated by 4# CFG_SCPFW_MOD_* swtches. SCP-firmware needs a C source and 5# a header file to be generated to describe embedded modules. 6# This is done through cmake configuration of the package. 7# The toolchain build directive must also
