Curious why does this have to be a white-list? As opposed to all - supported?

Hm. The current logic is that we have a list of (TOSA-)supported ops, a.k.a. ops that we have implemented. The support on Ethos-U55 is that list minus this list (and some additional constraints, these are just the completely unsupported ops) We don't have an explicit list of ops supported on Ethos-U55. Maybe I am missing your point 😬
