Linux-5.10移植
先进入kernel/linux/linux-5.10目录
patch -p1 < kernel/linux/patches/linux-5.10/rk3568_patch/kernel.patch
修改device/board/hihope/rk3568/kernel/build_kernel.sh
注释掉
//patch -p1 < ${KERNEL_PATCH}
把设备树放到kernel/linux/linux-5.10/arch/arm64/boot/dts/rockchip/目录
修改kernel/linux/linux-5.10/ make-ohos.sh
model_list=(
"TB-RK3568X0 arm64 0xfe660000 rk3568-toybrick-x0-linux Image rockchip_linux_defconfig"

)
CONFIG_DRM_PANEL_SIMPLE = y
kernel/linux/linux-5.10/drivers/gpu/drm/panel/panel-simple.c
注释掉
