I just skimmed over this for now, and it seems to look good. I have some gripes with the name BOARD_SUNXI though. Bad enough we have board-agnostic generic code in board/sunxi, but maybe we shouldn't add to the confusion. Would PLAT_SUNXI be a better name?

Yeah, I will definitely cherry-pick some patches, especially the more innocent ones. I will run my before/after defconfig comparisons to test them.
