Orange Pi R1 Plus is a Rockchip RK3328 based SBC by Xunlong. This device is similar to the NanoPi R2S, and has a 16MB SPI NOR (mx25l12805d). The reset button is changed to directly reset the power supply, another detail is that both network ports have independent MAC addresses. The device tree and description are taken from kernel v6.3-rc1. Reviewed-by: Kever Yang <kever.yang@rock-chips.com> Signed-off-by: Tianling Shen <cnsztl@gmail.com>
