[RFC PATCH 1/3] kbuild: introduce cmd_dtc_cpp

From: Stephen Warren <hidden>
Date: 2012-09-25 19:06:36 

From: Stephen Warren <redacted>

cmd_dtc_cpp runs the C pre-processor on the input .dts file before
passing it to dtc for final compilation. This allows used of #define
within the .dts file.

this should go to Makefile.build

and we should keep the same nomecalture as lds with lds.S

here dts.S

and is it possible to cmd with it

Best Regards,
