Hi Alif,

Just few comments:

- If possible make it inline, extra file means extra time to compile etc.
- To reduce the code size which I tested a bit, the text message is the easiest.
  So possible reuse or cleanup text print if needed.
- use "./scripts/checkpatch.pl" under the u-boot folder to clean things up.

Thanks,
Brian
