From: Stephen Warren Date: Wed, 24 Jul 2013 17:09:24 +0000 (-0700) Subject: dts/Makefile: pass -undef -D__DTS__ to cpp X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f53932addd3169839834829937a3cd7ae912f7ac;p=project%2Fbcm63xx%2Fu-boot.git dts/Makefile: pass -undef -D__DTS__ to cpp This brings U-Boot's cpp invocation into line with the way the Linux kernel invokes cpp on device trees. Consistency will be useful to ensure *.dts is portable between the two. -undef also has the added advantage of not defining "linux", so DT property names such as "linux,keymap" don't get mangled.
