It is a standard feature in U-Boot (and has always been right from the start with PPCBoot nearly 10 years ago) that we auto-detected the memory configuration on the boards, both for RAM and flash. Some boards / architectures did not bother to implement this, but the feature itself is present. The details depend on processor, memory controller properties, specific RAM types used, etc. In case of the Micron/Elpida issue on the ADS5121, that should be not too difficult to solve.
