missing spidev0.0 in /dev

Hello All,

I cannot find:

/dev/spidev0.0

/dev/spidev0.1

/dev/spidev1.1 on my Galileo Gen1 using iot-dev kit image.

According to  https://communities.intel.com/servlet/JiveServlet/previewBody/22488-102-1-26046/Quark_SWDevManLx_330235_001.pdf section 4.7, I tried "modprobe" but still cannot find it.

Can someone please help me on this?

Thanks
