The expected behavior is: - with legacy compatible "st,stm32mp1-m4" the Linux kernel loads a non-signed (ELF) firmware image, - with compatible "st,stm32mp1-m4-tee" the Linux kernel load a signed firmware image. In this case it calls TEE services to manage the firmware loading and the remoteproc life-cycle.
