OP-TEE images are normally packaged with type = "tee; os = "tee";
However, fit_image_load() thinks that is somehow invalid. However if they were declared as type = "kernel", os = "linux", fit_image_load() would happily accept them and allow the boot to continue. There is no technical limitation to excluding "tee".
Allowing "tee" images is useful in a boot flow where OP-TEE is executed before linux.
In fact, I think it's unintuitive for a "load"ing function to also do parsing and contain a bunch ad-hoc heuristics that only its caller might know. But I don't make the rules, I just write fixes. In more polite terms: refactoring the fit_image API is beyond the scope of this change.
