I guess the judges are still out on whether this should only be enabled in the defconfig or selected from the (really broad) ARCH_MXC symbol. My preference is also to have the select, but that means we my end up with a lot of drivers force-enabled that may not be relevant for the SoC the kernel is configured to run on. Like all the i.MX8M stuff being useless on i.MX8X.

So, Mani I think this should also fix the problem on i.MX8 QXP. Can you give it a try?
