The patch series removes PciExpressLib and enables CCIX port as PCIe root on N1SDP.
V4: - Remove PciExpressLib and use PciSegmentLib instead. More detailed explanation is included in the patch. V3: - The conditional logic in GetPciExpressAddress is made simple. - Removed few more PCD entries that were unused. - Removed hardcoded entries. V2: - Removed few PCDs entries that were not used. - Migrated to latest version edk2-platform and validated the patches. V1: - The PciExpressLib is updated to validate the PCIe addresses and introducing corresponding PCD entries. - A custom PCI Segment library is adapted from SynQuacerPciSegmentLib and ported for N1Sdp. - The root complex node info in PciHostBridge library is updated to include the CCIX port information.
