Subject[PATCH v4 0/7] jailhouse: Enhance secondary Jailhouse guest support /wrt PCI
Date
Basic x86 support [1] for running Linux as secondary Jailhouse [2] guest
is currently pending in the tip tree. This builds on top and enhances
the PCI support for x86 and also ARM guests (ARM[64] does not require
platform patches and works already).

Key elements of this series are:
- detection of Jailhouse via device tree hypervisor node
- function-level PCI scan if Jailhouse is detected
- MMCONFIG support for x86 guests

As most changes affect x86, I would suggest to route the series also via
tip after the necessary acks are collected.

Changes in v4:
- slit up Kconfig changes
- respect pcibios_last_bus during mmconfig setup
- cosmetic changes requested by Andy

Changes in v3:
- avoided duplicate scans of PCI functions under Jailhouse
- reformated PCI_MMCONFIG condition and rephrase related commit log

Changes in v2:
- adjusted commit log and include ordering in patch 2
- rebased over Linus master
