Hi Loïc

The Device Path is applicable across all architectures. There's nothing ARM 
specific.

As far as I know there's no registry of GUIDs. When GUIDs are used in Device 
Paths they are vendor specific and outside the remit of the UEFI specification. 
Perhaps some individual vendors maintain their own GUID registry?

Regards

Dan.

 I had a couple of questions on this:
 * is the definition ARM specific or across all arches?
 * is there a registry of GUID and allowed interfaces?
