Also - is Device_nGnRE a term uniform between ARM32 and ARM64?

Actually it should be Device-nGnRE to match with the spec. This has been
introduced on Armv8. Previously for Armv7, the name was "Device", although the
behavior is exactly the same.

I could say:

"ARM only; the region will be mapped in Stage-2 using the memory attribute
'Device-nGnRE' (previously named 'Device' on ARMv7)".

Small nit: I would say "the region gets mapped" or "is mapped" rather
than "will be" because that makes me think that it is a future behavior
of following Xen releases rather than the current behavior.

Good idea. I sent a v2 yesterday night [1]. So I will fix in the v3.
