Shouldn't this go to imxrt1050-evk-u-boot.dts?

This node is responsible for describing the DDR timings. Removing it will cause boot regression.

Yes it will. Linux doesn't have LCD or dram yet, it should be moved into imxrt1050-evk-u-boot.dtsi. If needed I can sync it as well as test.

Thanks, Jesse

I don't have access to this platform. Adding Jesse and Giulio.
