    The Workload is expecting to find a set of firmare images under

        * bl1.bin (BL1 = Stage 1 Bootloader)
        * fip.bin (FIP = Firmware Image Package):
            BL2, BL31, BL33 binaries compiled under a singe package

    These are the results of the compilation of Arm Trusted Firmware.
