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 := 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"? -- Cheers, Stephen Rothwell [unhandled content-type:application/pgp-signature] | |
