Skip the following Xen specific host device tree nodes/properties
from being included into hardware domain /chosen node:
- xen,static-heap: this property informs Xen about memory regions
reserved exclusively as static heap,
- xen,domain-shared-memory-v1: node with this compatible informs Xen
about static shared memory region for a domain. Xen exposes a different
node (under /reserved-memory with compatible "xen,shared-memory-v1") to
let domain know about the shared region,
- xen,evtchn-v1: node with this compatible informs Xen about static
event channel configuration for a domain. Xen does not expose
information about static event channels to domUs and dom0 case was
overlooked (by default nodes from host dt are copied to dom0 fdt unless
explicitly marked to be skipped), since the author's idea was not to
expose it (refer docs/misc/arm/device-tree/booting.txt, "Static Event
Channel"). Even if we wanted to expose the static event channel
information, the current node is in the wrong format (i.e. contains
phandle to domU node not visible by dom0). Lastly, this feature is
marked as tech-preview and there is no Linux dt binding in place.

Do we need Henry's explicit approval on bug fixes at this point?
I think it is a bit too early, we can wait for the code freeze for the
release-ack.
Before code freeze, maintainers/committers can push the patch as usual.
Anyway, I agree this patch is definitely qualified to be included in 4.18 so
feel
free to add below tag if you want.

Thanks. It is now committed.
Cheers,
