Hi Fengguang, I've recently run into a number of cases in which I pulled a branch that was building fine with "make vmlinux", but that failed for "make dtbs", and I wonder if this is something that could be checked by the kbuild test robot so we catch it earlier. There are parts of this: - running "make" without a target will build the default image file and also do the "dtbs" target on ARM and other architectures. I don't know if this is what you do, or if you always build "make vmlinux ; make modules", which doesn't include it. The dtbs makefile target is available on arc, arm, arm64, h8300, metag, mips, nios2, and xtensa but not the others, so if you call it explicitly, that has to be in an architecture specific way. - setting CONFIG_OF_ALL_DTBS will catch all files, not just the ones that are built by default for the set of configurations you have. It's possible to simply override this on the command line, using "make CONFIG_OF_ALL_DTBS=y", it doesn't actually have to be part of the configuration. The result is independent of the actual configuration, so it should be enough to do this once per architecture and source revision. Is this something you can add?
