Ann, Nikolay,

Currently on 1.8 (fido) of meta-fsl-arm we already have 3 different
product lines from Freescale: i.MX, Layerscape/QoirQ and Vybrid. And
currently the OVERRIDE "imx" is not exactly needed (if you think
everything has been working fine so far).

Please see [1], the heads (imx, vybrid and layerscape) are not from
the meta-fsl-arm source code, but faked for the picture.

Back to 1.6 RN I was able to find vybrid already being graphically
represented in a SOC Family tree.

So, the argument that imx is needed because of meta-freescale is not
right. Having a OVERRIDE for imx and vybrid and layerscape may make
sense because of some future differentiation on the BSP regarding
product lines.

On the other hand, if we have time, we can discuss it a lot. For
example, if you take the imx6, you see, from BSP point of view, we
have more diverging than converging packages. Would it make sense to
keep the "imx6" OVERRIDE today?

I would like to have the SOC_FAMILY tree reviewed for sure. I know we
have a lot of possible enhancement there. But I really don't get the
overall picture only with this patch.

And, the commit log is wrong. We already have non-imx machines in meta-fsl-arm.
