       *  Add "select ADD_FSP_PDAT_FILE"
       *  Add "select ADD_FSP_RAW_BIN"
       *  Add "select ADD_RMU_FILE"
    *  Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
    *  Place the pdat.bin files in the location specified by
    CONFIG_FSP_PDAT_FILE
    *  Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
    *  Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate
    UEFIPAYLOAD.fd
    *  Edit .config file and add the following lines:
       *  CONFIG_PAYLOAD_ELF=y
       *  CONFIG_PAYLOAD_FILE="path to UEFIPAYLOAD.fd"
    *  Testing successful when at the UEFI shell prompt:
       *  After issuing:
          *  "connect -r"
          *  "map -r"
       *  The "dir" command displays the contents of the SD flash card
       *  The "drivers" command shows an SD host and SD media connection
