Enabling SPI on SD410

Hi I'm trying to find instructions for enabling the SPI port on the SD410 for a yocto build, i.e. have a device file in place such as /dev/spidev1.0 so that I can run the spidev_test user space application. I haven't found any instructions for doing this for the SD410. I did find some for the VAR-SOM-MX6, but they didn't work.

What I've already tried.

Configure your kernel and add spidev driver. Device Drivers -> SPI support -> <*> User mode SPI device driver support

I ran "bitbake rpb-console-image -c menuconfig", but got the following error

ERROR: Task do_menuconfig does not exist for target rpb-console-image. Close matches:

If menuconfig isn't an option, would manually editing any particular files achieve the same ends, and if so which files with what edits?

Add spidev to your device tree

I don't really know exactly what to add or where.

Compile the Linux kernel and device tree

Obviously, I have't gotten to this stage yet.

Lastly, if there's a different preferred way to communicate over the SPI port that Variscite has, I'm open to such.
