I remove shared pin to gpio definition as needed , but i forgot that tv_out (that use PI12) in script.bin is enabled , now spidev appears!! My query to add spidev as module is confirmed ......

default cubian script.fex contain wrong 3 pinmux , correct pinmux is 2 (010) as reported below.

spi_cs0 = port:PI10 2 default> default> default> spi_sclk = port:PI11 2 default> default> default> spi_mosi = port:PI12 2 default> default> default> spi_miso = port:PI13 2 default> default> default>
