[U-Boot] [PATCH 0/7] rockchip: Split sdram common function into sdram_common.c

[Dr. Philipp Tomsich]

I just realised this myself after pulling it into my tree to take a closer look
and possibly give it a spin… my euphoria was gone rather quickly.

Since I have SPL set up for the 3368 and have all the "necessary notes”
(which usually leads into the realisation that there’s necessary and sufficient
are two very distinct concepts) on my desk to write the DRAM init code for it,
I might as well sit down and continue down this path.

We have quite a few RK3368-uQ7 modules in the lab—so having mainline
U-Boot support is becoming a priority.
