[edk2-devel] [PATCH v2 0/4] Add extra pci roots support for Arm

[Jiahui Cen via groups.io]

Changes with v1
v1->v2:
Separated into four patches.
Factor the same logic parts into a new library.

v1: https://edk2.groups.io/g/devel/topic/72723351#56901
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3059
QEMU: https://lore.kernel.org/qemu-devel/20201103120157.2286-1-cenjiahui@huawei.com/

This patch series adds support for extra pci roots for ARM.

In order to avoid duplicated codes, we introduce a new library
PciHostBridgeUtilityLib which extracts common interfaces from
OvmfPkg/PciHostBridgeLib. It provides conflicts informing and extra pci
roots scanning. Using the utility lib, the uefi could scan for extra
root buses and recognize multiple roots for ARM.
