I am trying to create a Yocto Warrior buid for the i.MX6Q SABRE SDP board that I have using the linux-fslc-lts-4.19 kernel.  In my local.conf file I have the following:

MACHINE = “imx6qdlsabresd”

DISTRO = "fslc-framebuffer”

PREFERRED_PROVIDER_virtual/kernel = "linux-fslc-lts-4.19”

When I try to build it fails saying it doesn’t know how to build imx6qp-sabresd-btwifi.dtb

 make[3]: *** No rule to make target 'arch/arm/boot/dts/imx6qp-sabresd-btwifi.dtb'.  Stop.

Is there some magic needed to only get it to use the default DTS file?
