Prior to the PCI series landing, and to enable dom0 to use ITS it might
be possible to call this from xen/arch/arm/platforms/thunderx.c via the
specific_mappings platform hook, which would also expose the PCI
controller to dom0 via a series of specific mmio mappings (look at
xen/arch/arm/platforms/xgene-storm.c for the sort of thing I mean).
That would, I think, give basic PCI functionality for dom0 (i.e.
allowing us to boot on thunderx) and decouple things from the PCI series
somewhat, which ought to make things easier overall IMHO.
Ian.
