Pick up latest branch from there. I'm prepping a rebased version
with some new stuff but might take a few more days.

Note my main development work is on arm64 so that tends to work
more reliably than x86 which I only lightly test for stuff that
isn't ready for upstream yet.

Give me a shout if you run into any problems.

The main blocker on upstreaming this is resolving the missing device tree
support for PCI expander bridges.  I've not made any progress on this since
talk at Linaro connect in 2023.
