CorebootPayloadPkg/CorebootPayloadPkgIa32X64.dsc seems to correctly include the general SerialDxe driver: # # ISA Support # MdeModulePkg/Universal/SerialDxe/SerialDxe.inf and on top of that, the terminal and console drivers: # # Console Support # MdeModulePkg/Universal/Console/ConPlatformDxe/ConPlatformDxe.inf MdeModulePkg/Universal/Console/ConSplitterDxe/ConSplitterDxe.inf MdeModulePkg/Universal/Console/GraphicsConsoleDxe/GraphicsConsoleDxe.inf MdeModulePkg/Universal/Console/TerminalDxe/TerminalDxe.inf I imagine SerialDxe is not configured correctly for the platform. Can you look into the PCDs that SerialDxe consumes (see the INF file), and/or whether "CorebootModulePkg/Library/BaseSerialPortLib16550/BaseSerialPortLib16550.inf", which SerialDxe depends on in the CorebootPayloadPkg build, is appropriate for your hardware? (This lib instance also consumes a large set of PCDs.)
