# Helper macro to build and install Trusted Services Secure Partitions (SPs).
# Invokes CMake to configure, and make to build and install the SP. (CMake's
# Makefile generator backend is used, we can run make in the build directory).
# Adds the SP output image to the optee_os_sp_paths list and complies the SP
# manifest dts to dtb.
#
# For information about the additional dependencies of the project, please see
# https://trusted-services.readthedocs.io/en/latest/developer/software-requirements.html
#
# Parameter list:
# 1 - SP deployment name (e.g. internal-trusted-storage, crypto, etc.)
# 2 - SP canonical UUID (e.g. dc1eef48-b17a-4ccf-ac8b-dfcff7711b14)
# 3 - SP additional build flags (e.g. -DTS_PLATFORM=<...>)
