@Gao, Liming In fact, I also want to move it edk2/MdeModulePkg/Include/UniversalPayload at master · tianocore/edk2 · GitHub to MdePkg step by step, but it another, for the mail thread we can focus on TraceHub Hob move to MdePkg responsibility. As you know, Intel silicon may also provide MMIO UART https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Include/UniversalPayload/SerialPortInfo.h This HOB need to provide by silicon code in the future will be made sense. We can review patch one by one and consider whether it’s make sense or not. In past, we discuss it with Mike, TraceHub can support UPL enable case and UPL disable case. So recommend us to put it into common area. It’s background.

For example, PCI Root Bridges HOB is defined in MdeModulePkg\Include\UniversalPayload\PciRootBridges.h. So, I think this definition should be placed in the same place.
