fb0 is the HDMI port on RaspberryPi. If there is no fb1 you have to check your setup for the SPI display. It should be part of the documentation for your display. Start by loading the modules for SPI and the display manually. Once that works use the device tree to load the modules.

The above applies to displays using fbtft module. Otherwise you have to use a compiled module supplied by the display manufacturer (which is always for a specific kernel / Raspbian version) or build it for your kernel.
