01 and 02 are kbuild cleanups.
03 and 04 parepare to wrap boot DTBs in scripts/Makefile.vmlinux.

My plan is to 05-13 to each arch ML in the next cycle, but they are included
in this patch set so that reviewers can understand what will happen in
the future.



Masahiro Yamada (15):
  kbuild: add intermediate targets for Flex/Bison in
    scripts/Makefile.host
  kbuild: split device tree build rules into scripts/Makefile.dtbs
  kbuild: move non-boot builtin DTBs to .init.rodata section
  kbuild: add generic support for built-in boot DTBs
  MIPS: migrate to generic rule for built-in DTBs
  riscv: migrate to the generic rule for built-in DTB
  LoongArch:  migrate to the generic rule for built-in DTB
  ARC: migrate to the generic rule for built-in DTB
  openrisc: migrate to the generic rule for built-in DTB
  xtensa: migrate to the generic rule for built-in DTB
  nios2: migrate to the generic rule for built-in DTB
  sh: migrate to the generic rule for built-in DTB
  microblaze: migrate to the generic rule for built-in DTB
  kbuild: rename CONFIG_GENERIC_BUILTIN_DTB to CONFIG_BUILTIN_DTB
  kbuild: use .init.rodata section unconditionally for cmd_wrap_S_dtb
