Who do you need to be able to find such memory? Or maybe I'm not
getting what or why you're asking...

don't think the domid field needs an explanation TBH.
Within the register, check if the device is newly added, then call
hypercall XENMEM_add_to_physmap to map the mmio regions.
For PCI bus device, it could reuse the existing PCI bus_notifier l

Can we make this OS agnostic? Could you explain what you mean with the
above sentence without using Linux kernel internals?

This document is going to explain the design details of Xen booting with
ACPI on ARM. Maybe parts of it may not be appropriate. Any comments are
welcome.
Changes v3->v4:
* add explanation for minimal DT and the properties
* drop "linux," prefix of the properties
* add explanation for the event cha
