More background information in case it matters.

I did my original setup with:
EULA=1 MACHINE =imx8mmevk DISTRO=poky source setup-environment build

... because I don't want/need graphics etc.

After Otavio did his change, I smoked sstate and tmp dir and rebuilt core-image-base.  Still get sdma errors and do not have /lib/firmware/imx / binaries.

Starting kernel ...
