The Xunlong Orange Pi 3B is a single-board computer based on the Rockchip RK3566 SoC. The two hw revisions use different io-voltage for Ethernet PHY and can be identified using GPIO4_C4: - v1.1.1: x (internal pull-down) - v2.1: PHY_RESET (external pull-up) Implement rk_board_late_init() to set correct fdtfile env var and board_fit_config_name_match() to load correct FIT config based on what board is detected at runtime so a single board target can be used for both hw revisions. Minimal DTs that includ DT from dts/upstream is added to support booting from both hw revision and only set Ethernet PHY io-voltage when the hw revision is detected at runtime. A side-affect of this is that defconfig show OF_UPSTREAM=n, however dts/upstream DTs is used for this board. Features tested on Orange Pi 3B 4GB (v1.1.1 and v2.1): - SD-card boot - eMMC boot - SPI Flash boot - Ethernet - PCIe/NVMe - USB host Signed-off-by: Ricardo Pardini <ricardo@pardini.net> Co-developed-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Jonas Karlman <jonas@kwiboo.se> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
