[PATCH v3 00/11] Power11 support for QEMU

[Aditya Gupta <adityag@linux.ibm.com>]

Overview
============

Add support for Power11 pseries and powernv machine types, to emulate VMs
running on Power11.

As Power11 core is same as Power10, hence much of the code has been reused from
Power10.

Power11 was added in Linux in:
  commit c2ed087ed35c ("powerpc: Add Power11 architected and raw mode")

Git Tree for Testing
====================

QEMU: https://github.com/adi-g15-ibm/qemu/tree/p11-v3

Has been tested with following cases:
* '-M pseries' / '-M pseries -cpu Power11'
* '-M powernv' / '-M powernv10' / '-M powernv11'
* '-smp' option tested
* with compat mode: 'max-cpu-compat=power10' and 'max-cpu-compat=power9'
* with/without device 'virtio-scsi-pci'
* with/without -kernel and -drive with qcow_file

skiboot with Power11 support: https://github.com/maheshsal/skiboot/tree/upstream_power11

Linux with Power11 support: https://github.com/torvalds/linux, since v6.9-rc1

Note: This patch series does not add tests as of now, and will be done as
soon as skiboot support for Power11 gets merged, and op-build adds a
release for Power11

Changelog
=========
v3:
  + patch #1: version power11 as power11_v2.0
  + patch #2: split target hw/pseries code into patch #2
  + patch #3,#4: fix regression due to Power10 and Power11 having same PCR
  + patch #5: create pnv_chip_power11_dt_populate and split pnv_chip_power10_common_realize as per review
  + patch #6-#11: no change
  - remove commit to make Power11 as default

v2:
  + split powernv patch into homer,lpc,occ,psi,sbe
  + reduce code duplication by reusing power10 code
  + make power11 as default
  + rebase on qemu upstream/master
  + add more information in commit descriptions
  + update docs
  + update skiboot.lid
