Enable building all dtb files when CONFIG_OF_ALL_DTBS is enabled. The dtbs are not really dependent on a platform being enabled or any other kernel config, so for testing coverage it is convenient to build all of the dtbs. In order to only build dtbs, this option can be used by creating an allno.config file containing: CONFIG_COMPILE_TEST=y CONFIG_OF=y CONFIG_OF_ALL_DTBS=y And then running: make KCONFIG_ALLCONFIG=1 allnoconfig make dtbs While building the dtbs themselves don't need a cross compiler, the scripts dependency does need one. This can be hacked around by commenting out "subdir-y += mod" in scripts/Makefile.
