Overview
========
This patch series merged two patch series sent earlier:
"Testcase improvements for PowerNV"
"Remove deprecated Power8E and 8NVL CPUs"
since the Power8E removal series depended on the former due to pnv-spi
test
Broadly contains 3 changes:
1. Testcase improvements:
Add a testcase to detect regression in remote interrupts when XIVE
changes,
since such regression had occurred during Power11 XIVE changes:
https://lore.kernel.org/qemu-devel/[email protected]/
Also add Power11 chip and testcase in qtests, and fadump functional
test
2. Power8E/Power8NVL removal
Power8E and Power8NVL were deprecated since QEMU 10.1, with
commit 264a604e7163 ("target/ppc: Deprecate Power8E and Power8NVL")
Hence, remove usage (chip and core types) of Power8E and 8NVL from
PowerNV,
PSeries as well as testcases.
3. Maintainer changes
Add myself as maintainer for PowerNV machine
Testing
=======
* Git tree for testing:

* Gitlab pipeline:
https://gitlab.com/adi-g15-ibm/qemu/-/pipelines/2635562383
* Successful ppc64 functional tests, qtests, boot tests, builds at all
commits
Changelog
=========
v3:
+ #3: use machine_type array in pnv_xscom_addr, as suggested by
shivang, harsh and balaton
v2:
+ #1: put e1000e on socket 1, and disable it's cpu, as suggested by
cedric
+ #1: pull out command fail checks into a helper, as suggested by
shivang
+ #2: use g_autofree, suggested by cedric
+ #3: use g_autofree in tests updated
+ #8: remove G:, as suggested by daniel
+ rebased to upstream
from previous split series:
+ #1: added checks to see if network is up and interrupts happened,
based on shivang's review
+ #3: replaced common if-else-if check for machine type with
pnv_get_machine_type
+ #7: added doc in removed-features, as suggested by cedric
+ #6,7: added rb from philippe
+ #8: new patch, maintainer change
