    SIO_SPI_1 for UART configuration

    yong_hou Green Belt

      Based on Apollo lake SOC which is in MRB board, we want to configure SIO_SPI_1 as one UART port according to the document #562447 (looks SPI_1 can be set as LPSS_UART3).

      however from Intel document #557555 EDS file: "the SPI functionality of SIO_SPI_1 and SIO_SPI_2 is not POR and these signals can be used as GPIOs ONLY."

      Can Intel clarify which one statement is correct ?
