This is easy solved by adding a COMPATIBLE_MACHINE to the imx-test
dummy recipe. I agree with this point.

We shouldn't. The BSP should be easy to extend. This is critical as
the meta-fsl-arm is used for public 3rd party boards but as well for
every custom board product which uses OE-Core-based build system (e.g
Yocto Project).

This imposes more metadata maintenance for no reason. Also breaks
package feeds of current products.

I am sorry but when I created the imx-test dummy, in 2012, it was to
make easy to support non-FSL-kernels without changing image per
machine. It was documented in the commit log:

    imx-test: Add a dummy package

    The dummy package allows for SoCs without imx-test compatible package
    to be used without the need of SoC specific changes in the default
    images.

    To achive it, we used a version 00.00.00 so it will be the "oldest"
    alternative for the recipe and being used only as a fallback.

The dummy package is not beautiful but a solution which scale. A way
nicer solution would be Freescale to fix imx-test and Linux kernel
mainline to properly support each other.
