after git apply the patch code

run 
```
export PATH=/data/tina_d1_h_v2.1/prebuilt/gcc/linux-x86/riscv/toolchain-thead-glibc/riscv64-glibc-gcc-thead_20200702/bin/:$PATH
cp arch/riscv/boot/dts/sunxi/uc_board.dts arch/riscv/boot/dts/sunxi/board.dts

make CROSS_COMPILE=riscv64-unknown-linux-gnu- ARCH=riscv sun20iw1p1_d1_r01_defconfig
make CROSS_COMPILE=riscv64-unknown-linux-gnu- ARCH=riscv -j2
make CROSS_COMPILE=riscv64-unknown-linux-gnu- ARCH=riscv INSTALL_MOD_PATH=test/rootfs/ modules_install
make CROSS_COMPILE=riscv64-unknown-linux-gnu- ARCH=riscv INSTALL_PATH=test/boot/ zinstall

```
to compile , you need to change the riscv64-glibc-gcc-thead_20200702 toolchain path to your real local path

after compiling you will get something like 

```
├── boot
│   ├── dt_board.dtb
│   ├── uc_board.dtb
│   └── vmlinuz-5.4.61+
└── rootfs
    └── lib
        └── modules
            └── 5.4.61+
```
