ophub/amlogic-s9xxx-openwrt — reverse-engineered prompt

Build me a project that helps turn supported Amlogic, Rockchip, and Allwinner TV boxes into OpenWrt routers.

I want it to produce ready to flash OpenWrt firmware images for common boxes like S905, S905X3, S922X, RK3588, RK3568, RK3399, and H6 devices. It should be easy for me to fork, pick a device, customize the OpenWrt packages I want, build the firmware locally or with GitHub Actions, then download the finished image from releases.

Please include clear scripts, simple setup instructions, a supported device guide, and safe defaults like root login info, SSH port, and the default router IP. It should also support installing to eMMC and updating the kernel when a newer supported kernel is available.

Keep it practical and beginner friendly. I’m okay with shell scripts and config files, but I want the workflow to feel guided and hard to mess up. Look up current OpenWrt docs online if you need to.
