      kbuild: handle dtb-y and CONFIG_OF_ALL_DTBS natively in Makefile.lib · 7e7962dd
      Masahiro Yamada authored
      If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each
      DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from
      the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile.
      It could be a race problem when building DTBS in parallel.
      
      Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor
      sub-directories, so this broke when Broadcom added one more hierarchy
      in arch/arm64/boot/dts/broadcom/<soc>/.
      
      One idea to fix the issues in a clean way is to move DTB handling
      to Kbuild core scripts.  Makefile.dtbinst already recognizes dtb-y
      natively, so it should not hurt to do so.
      
      Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is
      enabled.  All clutter things in Makefiles go away.
      
      As a bonus clean-up, I also removed dts-dirs.  Just use subdir-y
      directly to traverse sub-directories.
