MdeModulePkg/PciHostBridgeDxe is a superset of PcAtChipsetPkg/PciHostBridgeDxe. It requires a platform/silicon library instance PciHostBridgeLib which provides the information related to the how many root bridges the platform contains, and which range of MMIO/IO resources for each root bridge. It supports multiple segment access by layering on top of PciSegmentLib.
The PciHostBridgeLib header file path is MdeModulePkg/Include/Library/PciHostBridgeLib.h.

Hi Ruiyu, What's the diffience between PcAtChipsetPkg/PciHostBridgeDxe and MdeModulePkg/PciHostBridgeDxe ? We are now using PcAtChipsetPkg/PciHostBridgeDxe . We can move to MdeModulePkg/PciHostBridgeDxe if the new driver also works. It will be helpful we can know more detail information on MdeModulePkg/PciHostBridgeDxe .
