From b4f106be2d8a4eb34ce41c5306d5a4fcc37e60e3 Mon Sep 17 00:00:00 2001 From: Horst Kronstorfer Date: Fri, 13 Jul 2012 03:03:40 +0000 Subject: [PATCH] dts/Makefile: Turn off some predefined macros Add '-ansi' to DTS_CPPFLAGS to avoid unwanted expansion of dts content that matches some predefined macros. Example: A number of PowerPC related *.dts files in the kernel define a property named 'linux,network-index' which (w/o '-ansi') is expanded to '1,network-index' by the preprocessor because of '#define linux 1.'
