Hi Masahiro,

Thanks for these - I've applied patches 1-3, 5 & 6 to mips-next for
4.19.

This isn't really true - to generate the .its we actually do depend on
the ELF, which we read the entry address from (entry-y in
arch/mips/Makefile, provided to arch/mips/boot/Makefile as
VMLINUX_ENTRY_ADDRESS). In practice $(VMLINUX) is built before this
makefile is ever invoked anyway, but the dependency is there.

We don't need the vmlinux.bin.* file until we generate the .itb, so it
should be fine for the .its & .bin steps to be executed in parallel
which this patch would prevent.

Thanks,
    Paul
