The address was further down this introductory mail, in the footnote referenced by [0] above: https://github.com/linux-sunxi/u-boot-sunxi.git Log log from v3 to v4 is below. You can ignore the A23 and sun6i changes since they don't affect this initial upstreaming series.

And they can be supported, while keeping the PLL5P clock speed at least not higher than the DRAM clock speed. PLL5P output is used to clock a lot of peripherals, so we need to be careful not to break them (or more like some buggy code in the sunxi-3.4 kernel, which just sets hardcoded divisors in some places). Having 396MHz is nice. It can be used with the tight DDR3-800 timings (CL-tRCD-tRP-tRAS). For comparison, moving to 408MHz requires extra cycles for many of these timing parameters, which results in a latency increase. Having 512MHz and 540MHz is also useful, because they provide better granularity of the DRAM clock frequency selection around DDR3-1066 speed. And this is an interesting DRAM overclocking target. The extra five branches add ~120 bytes of code if compiled for ARM and ~90 bytes of code if compiled for Thumb2.
