You missed the $your_vendor placeholders, which you need to replace with the toolchain vendor you
configured for your Yocto Toolchain. If in doubt, just

apt install gcc-arm-linux-gnueabihf

and use CROSS_COMPILE=gcc-arm-linux-gnueabihf

You also need to install flex and bison.

You will note that device trees starting with imx6qdl always have a .dtsi extension,
which are device tree source _includes_. They aren't full device trees. Most importantly,
they miss the SoC nodes that differentiate between i.MX6 Quad and DualLite.

This is done this way, so you can have the same dtsi and use it in a dts once with imx6q.dtsi
and once more with imx6dl.dtsi without having to replicate the common parts on the SoM.

As for which one to use, depends on your board. If you have a Quad or Dual, use imx6q-$boardname,
if you have Dual Lite or Solo use imx6dl-.


Cheers
Ahmad
