I would expect them to work, they seemed happy when I was doing
the async mode support IIRC and a quick spin with -next in qemu
everything seems fine, I'm travelling so don't have the
environment for models to hand right now.

What are you using for EL3 with the model?  Both TF-A and
boot-wrapper are in regular use, TF-A gets *way* more testing
than boot-wrapper which is mostly used by individual developers.
