I will send it separately if the idea is accepted here. Yes, needs to go to devicetree-compiler list. I think this came up before and IIRC David wasn't completely in agreement. I looked briefly and couldn't find the thread though... We really don't need a different extension because we could just examine the dtb to determine if it is an overlay or not. That's less obvious. We could also add meta-data to overlays defining what base they apply to. If we had that, a tool could just list all overlays that should apply to a base and we could use that info for build time applying overlays. Of course, that and a dtbo extension/format are not mutually exclusive. > --- > scripts/dtc/dtc.c | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/scripts/dtc/dtc.c b/scripts/dtc/dtc.c > index bdb3f5945699..40fa7128b3d6 100644 > --- a/scripts/dtc/dtc.c > +++ b/scripts/dtc/dtc.c > @@ -357,6 +357,8 @@ int main(int argc, char *argv[]) > #endif > } else if (streq(outform, "dtb")) { > dt_to_blob(outf, dti, outversion); > + } else if (streq(outform, "dtbo")) { > + dt_to_blob(outf, dti, outversion); > } else if (streq(outform, "asm")) { > dt_to_asm(outf, dti, outversion); > } else if (streq(outform, "null")) { You also need to extend guess_type_by_name().
