Re: [U-Boot] [PATCH v1 3/9] sunxi: initial sun7i dram setup support

Unfortunately the only documentation we have on the sun7i DRAM controller is Allwinner boot0 + boot1 code, and that code uses.. magic numbers & shifts with no explanations.

To avoid having to explain this over-and-over again, the code could include some comment(s) pointing out that these are unexplained magic constants from Allwinner's code.
