VS-RK3288板卡HDMI显示uboot和kernel的logo图片

　　修改uboot源码：

　　include/configs/rk32plat.h

　　#define CONFIG_ROCKCHIP_MIPI_DSI

　　#define CONFIG_ROCKCHIP_DW_MIPI_DSI

　　#define CONFIG_ROCKCHIP_ANALOGIX_DP

　　+#define CONFIG_DRM_ROCKCHIP_DW_HDMI

　　#define CONFIG_ROCKCHIP_PANEL

　　#define CONFIG_I2C_EDID

　　#endIF

　　修改kernel源码：

　　/arch/ARM/boot/dts/rk3288-android.dtsi

　　connect = <&vopl_out_edp>;

　　};

　　+ route_hdmi: route-hdmi {

　　+ status = "disabLED";

　　+ logo,uboot = "logo.bmp";

　　+ logo,kernel = "logo_kernel.bmp";

　　+ logo,mode = "center";

　　+ charge_logo,mode = "center";

　　+ connect = <&vopb_out_hdmi>;

　　+ };

　　+

　　route_dsi0: route-dsi0 {

　　status = "disabled";

　　logo,uboot = "logo.bmp";

　　/arch/arm/boot/dts/rk3288-evb-android-rk808-mipi.dts

　　status = "okay";

　　};

　　+&route_hdmi {

　　+ status = "okay";

　　+ connect = <&vopb_out_hdmi>;

　　+};

　　+

　　&gpu {

　　status = "okay";

　　mali-supply = <&vdd_gpu>;

　　重新编译uboot和kernel，烧录并测试。
