Vineet Gupta a89516b31c ARC: [kbuild] Avoid DTB rebuilds if DTS are untouched ... Currently, for every ARC kernel build I see the following: --------------->8----------------- DTB arch/arc/boot/dts/angel4.dtb.S AS arch/arc/boot/dts/angel4.dtb.o LD arch/arc/boot/dts/built-in.o rm arch/arc/boot/dts/angel4.dtb.S <-- forces rebuild next iter CHK kernel/config_data.h --------------->8----------------- This is because *.dts.S is intermediate file in dtb generation and is by default deleted by make which needs a ".SECONDARY" hint to NOT do so. This could have ideally been done in scripts/Makefile.lib - for benefit of all, however .SECONDARY doesn't seem to work with wildcards. Thanks to Stephen for suggesting .SECONDARY (vs .PRECIOUS) and making that work using a non wildcard version in arch makefile. Thanks to James Hogan for pointing out that *.dtb.S now needs to be added to clean-files Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>		2013-04-17 18:19:14 +05:30
