[PATCH v2 0/3] xen: arm: Parse PCI DT nodes' ranges and interrupt-map

[Ian Campbell <ian.campbell@citrix.com>]

This series adds parsing of the DT ranges and interrupt-map properties
for PCI devices, these contain the MMIOs and IRQs used by children on
the bus. This replaces the specific mapping stuff on xgene.

This is pretty much a rewrite of v1, which was wrong in several aspects
relating to its parsing of the various properties.

There are several TODOs in the final patch, I'm mainly sending this now
because in [0] I suggested to Vijay that this might make the need for
the GSER specific mapping on ThunderX. Vijay, it would be great if you
could confirm or deny this in practice.

Suravee, I think you were interested in this for Seattle too so I'm
interested how you get on there.

I've tested on Mustang and on a FastModel with virtio-pci based rootfs.

Ian.
