Add foreign currency files to the file system

Save all the files to be added to rootfs in project/image/rootfs_add_Files/.
For example, add an audio file in wav format and put it into rootfs_ add_ Under files / Midea:

# mkdir ./project/image/rootfs_add_files/media
# mv ../ssd20x/pizzicato.wav  ./project/image/rootfs_add_files/media/

Implement the copy function in rootfs.mk:

 vi project/image/configs/i2m/rootfs.mk

Compile：

./Release_to_customer.sh -f nand -p ssd201 -o 2D06
