Revert "Ensure device tree DTS is compiled"
This reverts commit 27cb7300ffda7a3f1581f0f5a2d3bfe59b97ad67. I am not sure if I correctly understood the log of commit 27cb7300ffda ("Ensure device tree DTS is compiled"), but the code-diff looks like it was trying to solve the missed re-compilation when .dts was modified. Recently, commit 2737dfe096b6 ("kbuild: make arch-dtbs target PHONY") fixed the issue in a more correct and more complete way. Anyway, since the former commit, we see a clumsy log like this: make[2]: 'arch/sandbox/dts/sandbox.dtb' is up to date Another problem is, it created multiple paths to descend into arch/*/dts/, causing a race in parallel building. So, let's revert it. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
