This may become confusing and even lead to wrong results. For example, a composite DTB (created from a base DTB and a set of overlays) might have the same name as one of the overlays that create it. Different files should be generated from differently named sources. .dtb <-> .dts .dtbo <-> .dtso We do not remove the ability to compile DTBO files from .dts files here, only add a new rule allowing the .dtso file name. The current .dts named overlays can be renamed with time. After all have been renamed we can remove the other rule. [Import notes: Adapt to U-Boot by using the cmd_dtco function instead of cmd_dtc just like the current .dts -> .dtbo rule.] Signed-off-by: Rasmus Villemoes Reviewed-by: Simon Glass --- diff --git a/scripts/Makefile.lib b/scripts/Makefile.lib index 651d700369..7362a392ad 100644 --- a/scripts/Makefile.lib +++ b/scripts/Makefile.lib @@ -354,6 +354,9 @@ cmd_dtco = mkdir -p $(dir ${dtc-tmp}) ; \ $(obj)/%.dtbo: $(src)/%.dts $(DTC) FORCE $(call if_changed_dep,dtco) +$(obj)/%.dtbo: $(src)/%.dtso $(DTC) FORCE + $(call if_changed_dep,dtco) + # Fonts # ---------------------------------------------------------------------------
