From f53932addd3169839834829937a3cd7ae912f7ac Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 24 Jul 2013 10:09:24 -0700 Subject: [PATCH] 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.
