For rockpro64, I'm trying hard to get things up. neo4 I have tried
many options to dig into existing rk3399-sdram-ddr3-1866.dtsi to
produce 1GB timings but not succeed at the end.

True, indeed I even tried of disabling SPL for these boards but it
rather bit hard to manage lot of Kconfig options to rework since
rk3399 make the boards do use SPL by default. Since the work for ddr
in-progress I mark it as it is.
