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

And as for the rest of the code, lots of magic numbers to #define what/why (why udelay(2) and 22?)

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.

We have guessed some small bits, but a lot is completely unknown.
