SPIDev driver for lora sx1301 based mPCIe card on Atom

I’m trying to upgrade my lorawan concentrator OS. It came with Ubuntu 16.04 installed with kernel 3.0 and a SX1301 based mPCIe lora tranceiver. I can get the new kernel running but the necessary device file, /dev/spidev0.0, needed for the pkt forwarder to work is missing. Tons of articles on how to get the device file to show up on ARM based platforms but nothing for Atom. Has anyone had previous experience getting the spi mapped on Atom based systems?
