kbuild: remove head-y syntax

2022-10-02T09:06:03Z

Kbuild puts the objects listed in head-y at the head of vmlinux. Conventionally, we do this for head*.S, which contains the kernel entry point. A counter approach is to control the section order by the linker script. Actually, the code marked as __HEAD goes into the ".head.text" section, which is placed before the normal ".text" section. I do not know if both of them are needed. From the build system perspective, head-y is not mandatory. If you can achieve the proper code placement by the linker script only, it would be cleaner. I collected the current head-y objects into head-object-list.txt. It is a whitelist. My hope is it will be reduced in the long run.

mips: Always permit to build u-boot images

2022-03-07T12:11:20Z

The platforms where the kernel should be loaded above 0x8000.0000 do not support loading u-boot images, that doesn't mean that we shouldn't be able to generate them. Additionally, since commit 79876cc1d7b8 ("MIPS: new Kconfig option ZBOOT_LOAD_ADDRESS"), the $(zload-y) variable was no longer hardcoded, which made it impossible to use the uzImage.bin target.

MIPS: Makefile: Remove "ifdef need-compiler" for Kbuild.platforms

2021-12-14T09:02:48Z

After commit 13ceb48bc19c ("MIPS: Loongson2ef: Remove unnecessary {as,cc}-option calls"), no need to use "ifdef need-compiler" for Kbuild.platforms, because the cause of the build issue mentioned in commit 0706f74f719e ("MIPS: fix *-pkg builds for loongson2ef platform") has been disappeared, so just remove it.

MIPS: fix *-pkg builds for loongson2ef platform

2021-11-09T15:11:48Z

Since commit 805b2e1d427a ("kbuild: include Makefile.compiler only when compiler is needed"), package builds for the loongson2f platform fail. $ make ARCH=mips CROSS_COMPILE=mips64-linux- lemote2f_defconfig bindeb-pkg [ snip ] sh ./scripts/package/builddeb arch/mips/loongson2ef//Platform:36: *** only binutils >= 2.20.2 have needed option -mfix-loongson2f-nop.

Stop. In general, adding $(error ...) in the parse stage is troublesome, and it is pointless to check toolchains even if we are not building anything. Do not include Kbuild.platform in such cases.

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.
