[PATCH v2 00/20] ppc/pnv: Extend the powernv10 machine

["Cédric Le Goater" <clg@kaod.org>]

Hi,

This series adds the minimum set of models (XIVE2, PHB5) to boot a
baremetal POWER10 machine using the OpenPOWER firmware images.

The major change is the support for the interrupt controller of the
POWER10 processor. XIVE2 is very much like XIVE but the register
interface, the different MMIO regions, the XIVE internal descriptors
have gone through a major cleanup. It was easier to duplicate the
models then to try to adapt the current models. XIVE2 adds some new
set of features. Not all are modeled here but we add the
"Address-based trigger" mode which is activated by default on the
PHB5. When using ABT, the PHB5 offloads all interrupt management on
the IC, this to improve latency.

Thanks,

C.

Changes in v2:

  - Most comments on v1 have been addressed independently and merged
    in ppc-for-6.2.
