Some operating systems (e.g. seL4) and embedded applications are ELF images. It is convenient to use FIT-images to implement trusted boot. Added "elf" image type for booting using bootm command.

This does seem like snprintf would be useful here?
""" snprintf(str, 19, "0x%lx", images-ep); """
safest and also merges the two instructions in one.
Also, have another question, do we want to 0-left-pad the value so that it's always a 16 hex-digit number?
e.g. 0x%016lx
