Looking at the rest of the series, and then going back to v1 and:
https://lore.kernel.org/all/b6bc14fc-c823-4376-939f-2c0e6b120a2c@ti.com/
we're IH_TYPE_STANDALONE which *does* require a load address (see
boot/image-fit.c). You might need to look in to a new type or see if
another type is reasonable, that doesn't already expect a load address
set.
