OK, this is a problem right here.  First, the code no longer compiles as
we don't pass in "load_addr", which is what
imx_hab_authenticate_image() takes to know where in DDR the image is to
validate.  While I could probably work out that value from what we use
now for offset, I would rather someone that can test the code do so.
Thanks!
