RK3326 android10.0(Q) 横屏方案修改

开机logo横屏

U-boot logo 显示的两张图片是 kernel 根目录下的 logo.bmp 和 logo_kernel.bmp，如果
需要更换，用同名的**横屏 bmp **替换掉，重新编译 kernel
附：不一定要两张图片，可以只要一张，如果只有一张就保留 logo.bmp 这一张即可。

注：Android10.0的kernel.img和resource.img包含在boot.img中，更新编译kernel后需要在android根目
录下执行./mkimage.sh重新打包boot.img。打包后烧写rockdev下面的boot.img，即可查看效果。若烧录 kernel 文件夹下
的 boot.img，则设备无法正常开机。

开机动画横屏

修改 device/rockchip/common/BoardConfig.mk 中配置 BOOT_SHUTDOWN_ANIMATION_RINGING ?= true

制作资源图片均为横屏的开机动画，将开机动画.zip 复制到 device/rockchip/common/bootshutdown/bootanimation.zip (源码路径),

编译结束后会拷贝到 out 目录下 odm/media 中，烧写即可

Android 应用层显示横屏

device\rockchip\rk3326\BoardConfig.mk 中增加修改 SF_PRIMARY_DISPLAY_ORIENTATION := 90

搜索 SF_PRIMARY_DISPLAY_ORIENTATION 对应的文件，根据项目名称修改对应位置

./rockchip/common/device.mk:ifneq ($(filter 90 180 270, $(strip $(SF_PRIMARY_DISPLAY_ORIENTATION))), )
./rockchip/common/device.mk:	ro.surface_flinger.primary_display_orientation=ORIENTATION_$(SF_PRIMARY_DISPLAY_ORIENTATION)
./rockchip/common/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION ?= 0
./rockchip/rk3368/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION := 0
./rockchip/rk3326/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION := 0
./rockchip/rk3126c/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION := 0
./rockchip/rk3399/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION := 0
./rockchip/rk3368a/BoardConfig.mk:SF_PRIMARY_DISPLAY_ORIENTATION := 0

TP坐标,交换 x y 坐标实现旋转

gtp_change_x2y：x、y交换方向

gtp_x_reverse：x 方向坐标镜像

gtp_y_reverse：y 方向不镜像

RecoveryUI 横屏

rotation = GRRotation::LEFT; 270

rotation = GRRotation::DOWN; 180

rotation = GRRotation::RIGHT; 90

bootable\recovery\minui\graphics.cpp

int gr_init() {

  //cczheng add rotation = 1 for recoveryUI landscape
