reason meta-arm is needed for me is becuase meta-ti asks for it and now 
there is another dependency added so I am a bit not-nice to this because 
this serves no use for me as tf-a and tf-m are not even needed for 
machines of interest,  but it does show up on world builds and broke 
last time.

It doesn't do anything by simply adding the layer, if
