Re-testing with master as of Sep 12 and the wrong memory size continues to be detected (2G detected while the board has 4G).
The board has the following marking on it: Rockpro64_V2.1 2018-07-02 RAM Chips: PS052-053 BT 83RL I'd be happy to test any proposed patches to correct the memory size detection on this board.
