Added checks to FWU_SMC_IMAGE_COPY to prevent loading data into a memory region where another image data is already loaded.
Without this check, if two images are configured to be loaded in overlapping memory regions, one of them can be loaded and authenticated and the copy function is still able to load data from the second image on top of the first one. Since the first image is still in authenticated state, it can be executed, which could lead to the execution of unauthenticated arbitrary code of the second image.
Firmware update documentation updated.
