Rock960 is a family of boards based on Rockchip RK3399 SoC from Vamrs. It consists of Rock960 (Consumer Edition) and Ficus (Enterprise Edition) 96Boards.
Below are some of the key differences between both Rock960 and Ficus boards:
1. Different host enable GPIO for USB 2. Different power and reset GPIO for PCI-E 3. No Ethernet port on Rock960
The common board support will be utilized by both boards. The device tree has been organized in such a way that only the properties which differ between both boards are placed in the board specific dts and the reset of the nodes are placed in common dtsi file.
