The Allwinner R528/T113-s/D1/D1s SoCs all share the same die, so use the same DRAM initialisation code. Make use of prior art here and lift some code from awboot[1], which carried init code based on earlier decompilation efforts, but with a GPL2 license tag. This code has been heavily reworked and cleaned up, to match previous DRAM routines for other SoCs, and also to be closer to U-Boot's coding style and support routines. The actual DRAM chip timing parameters are included in the main file, since they cover all DRAM types, and are protected by a new Kconfig CONFIG_SUNXI_DRAM_TYPE symbol, which allows the compiler to pick only the relevant settings, at build time. The relevant DRAM chips/board specific configuration parameters are delivered via Kconfig, so this code here should work for all supported SoCs and DRAM chips combinations.
