Rock Pi 4b plus board is the successor of Rock Pi 4b board. Differences to the original version are - has RK3399 OP1 SoC revision - has eMMC (16 or 32 GB) soldered on board (no changes required, since it is enabled in rk3399-rock-pi-4.dtsi) - dev boards have SPI flash soldered, but as per manufacturer response, this won't be the case for mass production boards I didn't add yet another compatible, since the small set of differences are captured by the device tree.
