Awesome work!
I'd like to experiment with this series myself. Could there be some "cooking
recipe" in the board documentation for easy reproduction/failsafe tutorial? Is
there perhaps some Buildroot defconfig with the appropriate support enabled? Or
even better: Are there any binary images that could be used in a functional
test in addition?
Last but not least: Wouldn't it be useful if you became co-maintainer of the
imx8mp-evk? Perhaps the two sections in the MAINTAINERS file could be merged.
Best regards,
Bernhard
