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/mips/boot/Makefile

5f2fb52f - kbuild: rename hostprogs-y/always to hostprogs/always-y

Sat, 01 Feb 2020 16:49:24 +0000

kbuild: rename hostprogs-y/always to hostprogs/always-yIn old days, the "host-progs" syntax was used for specifying hostprograms. It was renamed to the current "hostprogs-y" in 2004.It is typically useful in scripts/Makefile because it allows Kbuild toselectively compile host programs based on the kernel configuration.This commit renames like follows: always -> always-y hostprogs-y -> hostprogsSo, scripts/Makefile will look like this: always-$(CONFIG_BUILD_BIN2C) += ... always-$(CONFIG_KALLSYMS) += ... ... hostprogs := $(always-y) $(always-m)I think this makes more sense because a host program is always a hostprogram, irrespective of the kernel configuration. We want to specifywhich ones to compile by CONFIG options, so always-y will be handier.The "always", "hostprogs-y", "hostprogs-m" will be kept for backwardcompatibility for a while.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/mips/boot/Makefile

858805b3 - kbuild: add $(BASH) to run scripts with bash-extension

Sun, 25 Aug 2019 13:28:37 +0000

kbuild: add $(BASH) to run scripts with bash-extensionCONFIG_SHELL falls back to sh when bash is not installed on the system,but nobody is testing such a case since bash is usually installed.So, shell scripts invoked by CONFIG_SHELL are only tested with bash.It makes it difficult to test whether the hashbang #!/bin/sh is real.For example, #!/bin/sh in arch/powerpc/kernel/prom_init_check.sh isfalse. (I fixed it up)Besides, some shell scripts invoked by CONFIG_SHELL use bash-extensionand #!/bin/bash is specified as the hashbang, while CONFIG_SHELL maynot always be set to bash.Probably, the right thing to do is to introduce BASH, which is bash bydefault, and always set CONFIG_SHELL to sh. Replace $(CONFIG_SHELL)with $(BASH) for bash scripts.If somebody tries to add bash-extension to a #!/bin/sh script, it willbe caught in testing because /bin/sh is a symlink to dash on some majordistributions.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/mips/boot/Makefile

afa974b7 - kbuild: add real-prereqs shorthand for $(filter-out FORCE,$^)

Thu, 17 Jan 2019 10:02:43 +0000

kbuild: add real-prereqs shorthand for $(filter-out FORCE,$^)In Kbuild, if_changed and friends must have FORCE as a prerequisite.Hence, $(filter-out FORCE,$^) or $(filter-out $(PHONY),$^) is a commonidiom to get the names of all the prerequisites except phony targets.Add real-prereqs as a shorthand.Note:We cannot replace $(filter %.o,$^) in cmd_link_multi-m because $^ mayinclude auto-generated dependencies from the .*.cmd file when a singleobject module is changed into a multi object module.

eed0eabd - MIPS: generic: Introduce generic DT-based board support

Wed, 05 Oct 2016 17:18:20 +0000

MIPS: generic: Introduce generic DT-based board supportIntroduce a "generic" platform, which aims to be board-agnostic bymaking use of device trees passed by the boot protocol defined in theMIPS UHI (Universal Hosting Interface) specification. Provision is madefor supporting boards which use a legacy boot protocol that can't bechanged, but adding support for such boards or any others is left tofollowon patches.Right now the built kernels expect to be loaded to 0x80100000, ie. inkseg0. This is fine for the vast majority of MIPS platforms, butnevertheless it would be good to remove this limitation in the future bymapping the kernel via the TLB such that it can be loaded anywhere & mapitself appropriately.Configuration is handled by dynamically generating configs usingscripts/kconfig/merge_config.sh, somewhat similar to the way powerpcmakes use of it. This allows for variations upon the configuration, eg.differing architecture revisions or subsets of driver support fordiffering boards, to be handled without having a large number ofdefconfig files.Signed-off-by: Paul Burton Cc: linux-mips@linux-mips.orgPatchwork: https://patchwork.linux-mips.org/patch/14353/Signed-off-by: Ralf Baechle List of files: /linux-6.15/arch/mips/boot/Makefile

cf2a5e0b - MIPS: Support generating Flattened Image Trees (.itb)

Wed, 05 Oct 2016 17:18:19 +0000

MIPS: Support generating Flattened Image Trees (.itb)Add support for generating kernel images in the Flattened Image Tree(.itb) format as supported by U-Boot. This format is essentially aFlattened Device Tree binary containing images (kernels, DTBs, ramdisks)and configurations which link those images together. The big advantagesof FIT images over the uImage format are: - We can include FDTs in the kernel image in a way that the bootloader can extract it & manipulate it before providing it to the kernel. Thus we can ship FDTs as part of the kernel giving us the advantages of being able to develop & maintain the DT within the kernel tree, but also have the benefits of the bootloader being able to manipulate the FDT. Example uses for this would be to inject the kernel command line into the chosen node, or to fill in the correct memory size. - We can include multiple configurations in a single kernel image. This means that a single FIT image can, given appropriate bootloaders, be booted on different boards with the bootloader selecting an appropriate configuration & providing the correct FDT to the kernel. - We can support a multitude of hashes over the data.Signed-off-by: Paul Burton Cc: linux-mips@linux-mips.orgPatchwork: https://patchwork.linux-mips.org/patch/14352/Signed-off-by: Ralf Baechle List of files: /linux-6.15/arch/mips/boot/Makefile
