kbuild: use more subdir- for visiting subdirectories while cleaning

2021-10-24T04:49:46Z

Documentation/kbuild/makefiles.rst suggests to use "archclean" for cleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement. Since commit d92cc4d51643 ("kbuild: require all architectures to have arch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick for all architectures. This can take advantage of the parallel option (-j) for "make clean". I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep" target no longer exists.

Describe the subdirectories under arch/openrisc/ in arch/openrisc/Kbuild so you can use the standard obj-y syntax. I removed the CONFIG_OPENRISC_BUILTIN_DTB conditional because it is already controlled by arch/openrisc/boot/dts/Makefile. Signed-off-by: Masahiro Yamada Signed-off-by: Stafford Horne
