You are right. Thanks for catching this. -- Best Regards Masahiro Yamada

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

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
