+Someone created a thread on the U-Boot mailing list [1], referencing work
+done to support variants of RK3399 SoCs with different types of DRAM [2].
+This patch configures the Nano Pi R4S to use DDR3 instead of LPDDR4, but
+will be removed once [2] is included in a future U-Boot release. This
+patch was created around April 2023 by Herman Rimm <herman@rimm.ee> for
+personal use and has only been submitted to GNU Guix.
