[Qemu-ppc] [PATCH 00/15] spapr: Add support for PHB hotplug

[Greg Kurz]

Previous work on PHB hotplug was last posted more than one year ago:

https://lists.gnu.org/archive/html/qemu-devel/2017-07/msg07906.html

Quite a few significant changes happened since then:
- fixed PHB indexes
- fixed IRQ numbers for LSIs
- SLOF capable of updating the FDT in QEMU
- XIVE

First step in this new series is to teach QEMU how to get the FDT from
SLOF thanks to the recent patch from Alexey, rebased against David's
ppc-for-4.0 branch (SHA1: 11ce774130e7).

Most of the other patches come from the previous version with minor
modifications, but I guess even the ones with Reviewed-by tags deserve
to be reviewed again in case I've missed something.

Finally, the XIVE and XICS backends are changed to expose the name of
the interrupt controller node in the device tree. The machine code can
then exploit this to reach out to its phandle property, in case it got
changed by SLOF. This is needed to wire up interrupts during hotplug.

This was only lightly tested at the moment. I'll post about that later.

Please comment.

Cheers,
