It is intended for use by post-ROM boot stage components, via the ROM Vector Table, in order to avoid configuring security-sensitive peripherals, or loading images over sensitive memory regions or outside recognized memory devices in the address map." It is a useful function to support as a precursor to calling into authenticate_image() to validate the target memory region is good.
