ce697cce - kbuild: remove head-y syntax

Sat, 24 Sep 2022 18:19:15 +0000

kbuild: remove head-y syntaxKbuild puts the objects listed in head-y at the head of vmlinux.Conventionally, we do this for head*.S, which contains the kernel entrypoint.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 systemperspective, head-y is not mandatory. If you can achieve the proper codeplacement by the linker script only, it would be cleaner.I collected the current head-y objects into head-object-list.txt. It isa whitelist. My hope is it will be reduced in the long run.Signed-off-by: Masahiro Yamada Tested-by: Nick Desaulniers Reviewed-by: Nicolas Schier List of files: /linux-6.15/arch/nios2/Makefile

f774f5bb - kbuild: factor out the common installation code into scripts/install.sh

Tue, 03 May 2022 02:47:16 +0000

kbuild: factor out the common installation code into scripts/install.shMany architectures have similar install.sh scripts.The first half is really generic; it verifies that the kernel imageand System.map exist, then executes ~/bin/${INSTALLKERNEL} or/sbin/${INSTALLKERNEL} if available.The second half is kind of arch-specific; it copies the kernel imageand System.map to the destination, but the code is slightly different.Factor out the generic part into scripts/install.sh.Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier List of files: /linux-6.15/arch/nios2/Makefile

8212f898 - kbuild: use more subdir- for visiting subdirectories while cleaning

Wed, 13 Oct 2021 06:36:22 +0000

kbuild: use more subdir- for visiting subdirectories while cleaningDocumentation/kbuild/makefiles.rst suggests to use "archclean" forcleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement.Since commit d92cc4d51643 ("kbuild: require all architectures to havearch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick forall 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.Signed-off-by: Masahiro Yamada Reviewed-by: Kees Cook Acked-by: Geert Uytterhoeven Acked-by: Michael Ellerman (powerpc) List of files: /linux-6.15/arch/nios2/Makefile

37c8a5fa - kbuild: consolidate Devicetree dtb build rules

Wed, 10 Jan 2018 21:19:37 +0000

kbuild: consolidate Devicetree dtb build rulesThere is nothing arch specific about building dtb files other than theirlocation under /arch/*/boot/dts/. Keeping each arch aligned is a pain.The dependencies and supported targets are all slightly different.Also, a cross-compiler for each arch is needed, but really the hostcompiler preprocessor is perfectly fine for building dtbs. Move thebuild rules to a common location and remove the arch specific ones. Thisis done in a single step to avoid warnings about overriding rules.The build dependencies had been a mixture of 'scripts' and/or 'prepare'.These pull in several dependencies some of which need a target compiler(specifically devicetable-offsets.h) and aren't needed to build dtbs.All that is really needed is dtc, so adjust the dependencies to only bedtc.This change enables support 'dtbs_install' on some arches which weremissing the target.Acked-by: Will Deacon Acked-by: Paul Burton Acked-by: Ley Foon Tan Acked-by: Masahiro Yamada Cc: Michal Marek Cc: Vineet Gupta Cc: Russell King Cc: Catalin Marinas Cc: Yoshinori Sato Cc: Michal Simek Cc: Ralf Baechle Cc: James Hogan Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Cc: Michael Ellerman Cc: Chris Zankel Cc: Max Filippov Cc: linux-kbuild@vger.kernel.orgCc: linux-snps-arc@lists.infradead.orgCc: linux-arm-kernel@lists.infradead.orgCc: uclinux-h8-devel@lists.sourceforge.jpCc: linux-mips@linux-mips.orgCc: nios2-dev@lists.rocketboards.orgCc: linuxppc-dev@lists.ozlabs.orgCc: linux-xtensa@linux-xtensa.orgSigned-off-by: Rob Herring List of files: /linux-6.15/arch/nios2/Makefile

1b4f9e2b - nios2: use common rules to build built-in dtb

Wed, 01 Aug 2018 20:14:12 +0000

nios2: use common rules to build built-in dtbUsing the common build support for built-in dtb files just requiresadding a .dtb.o target to obj-y.This has the side effect that CONFIG_NIOS2_DTB_SOURCE should now be justthe dts filename in arch/nios2/boot/dts/ directory. Before any path wassupported, but if you want to build in your dtb to the kernel, it shouldbe in the kernel tree.Cc: Ley Foon Tan Cc: nios2-dev@lists.rocketboards.orgSigned-off-by: Rob Herring List of files: /linux-6.15/arch/nios2/Makefile

Thu, 08 Oct 2015 00:21:18 +0000

nios2: build .dtb files in dts directoryAlign nios2 with other architectures which build the dtb files in thesame directory as the dts files. This is also in line with most otherbuild targets which are located in the same directory as the source.This move will help enable the 'dtbs' target which builds all the dtbsregardless of kernel config.This transition could break some scripts if they expect dtb files inthe old location.Cc: Ley Foon Tan Cc: nios2-dev@lists.rocketboards.orgSigned-off-by: Rob Herring List of files: /linux-6.15/arch/nios2/Makefile
