How to make .dtb from .dts file (how to set include path for #include .. ?)

[ckim at etri.re.kr]

Hello Ahmad,

Thanks for the kind reply.
I've checked adding a .dts file in the directory and adding it in the
Makefile there, and doing "make dts" at the build top does the job. As you
said, I think I can just do with this method.
Thank you!
Best regards,

Chan
