Once the kernel is loaded and and the android system is initializing there is a bootanimation that is shown. Documentation for the format can be found online. Source for triggering it is in a strange place in the aosp source tree (`./frameworks/base/cmds/bootanimation`). For the most part, once you have a bootanimation.zip that you want to use you can place it in the device folder (`device/rockchip/rk312x`) and use the following in your device.mk to copy it to the correct location. The system should just play it once it finds it there. Once the kernel is loaded and and the android system is initializing there is a bootanimation that is shown.
