2. Make mkimage

iMX8 is pretty different with iMX6, and actually... not completed enough.
With hybrid structure, bootloader of iMX8 including both uefi and uboot.
Which make us have to build mkimage for booting up.

3. Copy Kernel

• Note: Make sure you already finished setting up SD card partition! Detail: SD Card Setup Run create_kernel.sh, which clones the kernel source code and compile it automatically.
  Run copy_kernel.sh, which copies kernel Image and dtb to SD card.

4. Dump Busybox

Run dump_busybox.sh, which decompresses busybox.tgz and copy it to SD card.
