Traditionally we assumed that every Allwinner board would come with at least 256 MB of DRAM, and set our DRAM layout accordingly. This affected both the default load addresses, but also U-Boot's own address expectations (like being loaded at 160 MB). Some SoCs come with co-packaged DRAM, but only provide 32 or 64MB. So far we special-cased those *chips*, as there was only one chip per DRAM size. However new chips force us to take a more general approach. Introduce a Kconfig symbol, which provides the minimum DRAM size of the board. If nothing else is specified, we use 256 MB, and default to smaller values for those co-packaged SoCs. Then select the different DRAM maps according to this new symbol, so that different SoCs with the same DRAM size can share those definitions. Inspired by an idea from Icenowy. This is just refactoring: compiled for all boards before and after this patch: the binaries were identical.
