[RK3588 Android12]修改开机logo和播放开机视频

1.修改开机logo

替换kernel-5.10/logo.bmp和logo_kernel.bmp两个图片文件即可修改开机logo，替换后编译报错
error: out/target/product/rk3588_s/boot.img too large (50720768 > 41943040)
修改device/rockchip/common/build/rockchip/Partitions.mk
BOARD_BOOTIMAGE_PARTITION_SIZE的值，将该值改大一些。

2.播放开机视频

查看源码framework/base/cmds/bootanimation/BootAnimation.cpp
可以看到视频存放位置
static const char DATA_BOOTVIDEO_FILE[] = “/data/local/bootanimation.ts”;
static const char SYSTEM_BOOTVIDEO_FILE[] = “/product/media/bootanimation.ts”;

将视频放在device/rockchip/rk3588/下，并改名为bootanimation.ts；
修改device/rockchip/rk3588/device.mk，添加
PRODUCT_COPY_FILES +=
$(LOCAL_PATH)/bootanimation.ts:/product/media/bootanimation.ts
以及
persist.sys.bootvideo.enable = true

3.开机视频播放异常

开机视频会出现不居中显示问题，这主要是开机视频使用的是原始的显示设备宽高，当系统服务起来后，DisplayManagerService获取到display的override信息后会更新分辨率配置信息，因此修改bootanimation获取显示设备的宽高值解决该问题，
修改framework/base/cmds/bootanimation/BootAnimation.cpp中的status_t BootAnimation::readyToRun() 函数，添加如下代码

diff --git a/frameworks/base/cmds/bootanimation/BootAnimation.cpp b/frameworks/base/cmds/bootanimation/BootAnimation.cpp
index 26345c12fd..97e58d039b 100644--- a/frameworks/base/cmds/bootanimation/BootAnimation.cpp

     sp<SurfaceControl> control =session()->createSurface(String8("BootAnimation"),
             resolution.getWidth(), resolution.getHeight(), PIXEL_FORMAT_RGB_565);

解决音视频不同步问题，修改device/rockchip/rk3588/device.mk，添加persist.sys.bootvideo.delaytime = 3
