Out of curiosity, what is the rule for when things are 'm' vs 'y'?

In the Code Aurora repo, it is set to 'y' and the mainline kernel for
the i.MX6/7, the imx_v6_v7_defconfig is also set to 'y' which is why I
used 'y' here.

I can do a V3 to address the other items you noted, but I want to
understand the rules about the defconfig so I don't make the same
mistake again.

thanks,
