Ummm, arm builds (and many others) select CONFIG_OF_EARLY_FLATTREE (in the case of arm, only if CONFIG_OF is set), and the top level Makefile does this: ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/boot/dts/),) dtstree :=3D arch/$(SRCARCH)/boot/dts endif ifneq ($(dtstree),) . . . ifdef CONFIG_OF_EARLY_FLATTREE all: dtbs endif endif So won't this be the same as doing a separate "make dtbs"? --=20 Cheers, Stephen Rothwell --Sig_/XKZDKnVq=yDSY_XGcsQaGHc Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmUvdvUACgkQAVBC80lX 0GwkKQf+IWyF+mZXfIODoybrGBaxaP/eKxHuTHcfCWlF2bGBlIHVawjjisO7Y7en XRSHKCHoch/OxrnXrxIj6o+nw0LPnkgwMDujuVrWAtz5dhgKpWpJI0S2WO6bpDj4 I6CBpp+X7Pe6PQ1U00vVkJX5UDCu4NaiUTy9VuoH/DPrTRf9Va9MzE0IetERz7Pt 3boOgJG1MNZMPnqEJY1LuKFdA1lVih6InH1Jc5B1H1hACAdTHOrlYiDdcqgSAFjV XgbzrvcAedFeBZS/m9cXGDdWWLU8S4Kh9ifmqEeMMFRGMzzC0QQ6G4sNfwg8Ddsb kandqhOvxPRl723cVC4SYRg5cdYp3w== =5H1I -----END PGP SIGNATURE----- --Sig_/XKZDKnVq=yDSY_XGcsQaGHc--
