@@ -381,6 +381,10 @@ To enable video you must enable these options in coreboot:
    - Set framebuffer graphics resolution (1280x1024 32k-color (1:5:5))
    - Keep VESA framebuffer
 
+And include coreboot_fb.dtsi in your board's device tree source file, like:
+
+   /include/ "coreboot_fb.dtsi"
+
 At present it seems that for Minnowboard Max, coreboot does not pass through
 the video information correctly (it always says the resolution is 0x0). This
 works correctly for link though.
