From: Stephen Warren Date: Wed, 6 Mar 2013 17:58:37 +0000 (-0700) Subject: kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b40b25ff;p=linux-beck.git kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp Replace cmd_dtc with cmd_dtc_cpp, and delete the latter. Previously, a special file extension (.dtsp) was required to trigger the C pre-processor to run on device tree files. This was ugly. Now that previous changes have enhanced cmd_dtc_cpp to collect dependency information from both gcc -E and dtc, we can transparently run the pre- processor on all device tree files, irrespective of whether they use /include/ or #include syntax to include *.dtsi.
