Hi all,

This is the remaining series for the full functional "dynamic node
programming using overlay dtbo" feature. The first part [1] has
already been merged.

Quoting from the original series, the first part has already made
Xen aware of new device tree node which means updating the dt_host
with overlay node information, and in this series, the goal is to
map IRQ and IOMMU during runtime, where we will do the actual IOMMU
and IRQ mapping to a running domain and will call unmap_mmio_regions()
to remove the mapping.

Also, documentation of the "dynamic node programming using overlay dtbo"
feature is added.

Patch 1 is a fix of [1] which is noticed during my local test, details
please see the commit message.

Gitlab CI for this series can be found in [2].

For all the replies I sent, Vikram's addresses - Xilinx or AMD - bounced.
What's the value of Cc-ing dead addresses?
