@davemgreen yes, this does change the cortex-r52 default features as well. The 
problem is that the cortex-r52 is the "default" CPU for armv8r (probably 
because it's the only one), so if I don't reduce the feature set of that CPU, 
armv8r will continue to imply features that are not true of all processors in 
that family. I can add this to the release notes if there's no other way to 
achieve what is needed here. Would removing the default CPU for armv8r be 
acceptable?
Regardless, this is an intentional behavior change because currently you get 
all neon and dp features just by using this architecture, so I can add release 
notes.
