As currently the board uses the mainline kernel, it does not offers
the i.MX specific headers and drivers so the recipes which require
those drivers and headers won't build.

Some of the recipes going to fail are:

Until someone adds proper support for the board in the linux-fslc-imx
it cannot be enabled. Same is valid for WaRP.

Good, so you could instead contribute with the community and prepare
proper patches,

This is not wrong, it is a valid architecture for a Cortex A9. In fact
I have customers which use it due valid reasons.
