Hi, Thanks for the dram timing patches. Since they do not make any changes without them being explictly enabled in Kconfig, I've queued up patches 1 2 into u-boot-sunxi/next for merging upstream. I would like to see this one handled slightly different though, see below. I assume you're also

[U-Boot] [PATCH 3/3] sunxi: dram: Allow to configure vdd-dll voltage on sun[457]i

Higher vdd-dll voltage allows to use higher dram and mbus clock speeds. The vdd-int/vdd-dll voltage is currently set to 1.25V by default, which is much lower than 1.4V, allowed by datasheets (the exact maximum differs for different SoCs). There are different use cases. For a tablet, it may be
