21bcc499 - sh: Migrate to the generic rule for built-in DTB

Sun, 22 Dec 2024 00:32:07 +0000

sh: Migrate to the generic rule for built-in DTBCommit 654102df2ac2 ("kbuild: add generic support for built-inboot DTBs") introduced generic support for built-in DTBs.Select GENERIC_BUILTIN_DTB when built-in DTB support is enabled.To keep consistency across architectures, this commit also renamesCONFIG_USE_BUILTIN_DTB to CONFIG_BUILTIN_DTB, andCONFIG_BUILTIN_DTB_SOURCE to CONFIG_BUILTIN_DTB_NAME.Signed-off-by: Masahiro Yamada Reviewed-by: John Paul Adrian Glaubitz Signed-off-by: John Paul Adrian Glaubitz List of files: /linux-6.15/scripts/dtc/include-prefixes/sh/Makefile

129ab0d2 - kbuild: do not quote string values in include/config/auto.conf

Tue, 14 Dec 2021 02:53:53 +0000

kbuild: do not quote string values in include/config/auto.confThe previous commit fixed up all shell scripts to not includeinclude/config/auto.conf.Now that include/config/auto.conf is only included by Makefiles,we can change it into a more Make-friendly form.Previously, Kconfig output string values enclosed with double-quotes(both in the .config and include/config/auto.conf): CONFIG_X="foo bar"Unlike shell, Make handles double-quotes (and single-quotes as well)verbatim. We must rip them off when used.There are some patterns: [1] $(patsubst "%",%,$(CONFIG_X)) [2] $(CONFIG_X:"%"=%) [3] $(subst ",,$(CONFIG_X)) [4] $(shell echo $(CONFIG_X))These are not only ugly, but also fragile.[1] and [2] do not work if the value contains spaces, like CONFIG_X=" foo bar "[3] does not work correctly if the value contains double-quotes like CONFIG_X="foo\"bar"[4] seems to work better, but has a cost of forking a process.Anyway, quoted strings were always PITA for our Makefiles.This commit changes Kconfig to stop quoting in include/config/auto.conf.These are the string type symbols referenced in Makefiles or scripts: ACPI_CUSTOM_DSDT_FILE ARC_BUILTIN_DTB_NAME ARC_TUNE_MCPU BUILTIN_DTB_SOURCE CC_IMPLICIT_FALLTHROUGH CC_VERSION_TEXT CFG80211_EXTRA_REGDB_KEYDIR EXTRA_FIRMWARE EXTRA_FIRMWARE_DIR EXTRA_TARGETS H8300_BUILTIN_DTB INITRAMFS_SOURCE LOCALVERSION MODULE_SIG_HASH MODULE_SIG_KEY NDS32_BUILTIN_DTB NIOS2_DTB_SOURCE OPENRISC_BUILTIN_DTB SOC_CANAAN_K210_DTB_SOURCE SYSTEM_BLACKLIST_HASH_LIST SYSTEM_REVOCATION_KEYS SYSTEM_TRUSTED_KEYS TARGET_CPU UNUSED_KSYMS_WHITELIST XILINX_MICROBLAZE0_FAMILY XILINX_MICROBLAZE0_HW_VER XTENSA_VARIANT_NAMEI checked them one by one, and fixed up the code where necessary.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/scripts/dtc/include-prefixes/sh/Makefile

207a369e - sh: fix build error for invisible CONFIG_BUILTIN_DTB_SOURCE

Mon, 04 Feb 2019 09:10:55 +0000

sh: fix build error for invisible CONFIG_BUILTIN_DTB_SOURCEI fixed a similar build error in commit 1b1e4ee86e00 ("sh: fix builderror for empty CONFIG_BUILTIN_DTB_SOURCE"), but it came back again.Since commit 37c8a5fafa3b ("kbuild: consolidate Devicetree dtbbuild rules"), the combination of CONFIG_OF_EARLY_FLATTREE=y andCONFIG_USE_BUILTIN_DTB=n results in the following build error: make[1]: *** No rule to make target 'arch/sh/boot/dts/.dtb.o', needed by 'arch/sh/boot/dts/built-in.a'. Stop.Prior to that commit, there was only one path to descend intoarch/sh/boot/dts/, and arch/sh/Makefile correctly guards it withCONFIG_USE_BUILTIN_DTB: core-$(CONFIG_USE_BUILTIN_DTB) += arch/sh/boot/dts/Now, there is another path to descend there from the top Makefilewhen CONFIG_OF_EARLY_FLATTREE=y. If CONFIG_USE_BUILTIN_DTB is disabled,CONFIG_BUILTIN_DTB_SOURCE is invisible instead of defined as "".Add obj-$(CONFIG_USE_BUILTIN_DTB) guard to avoid the attempt to buildthe non-existing file.Fixes: 37c8a5fafa3b ("kbuild: consolidate Devicetree dtb build rules")Reported-by: kbuild test robot Signed-off-by: Masahiro Yamada List of files: /linux-6.15/scripts/dtc/include-prefixes/sh/Makefile

1b1e4ee8 - sh: fix build error for empty CONFIG_BUILTIN_DTB_SOURCE

Mon, 19 Feb 2018 17:09:42 +0000

sh: fix build error for empty CONFIG_BUILTIN_DTB_SOURCEIf CONFIG_USE_BUILTIN_DTB is enabled, but CONFIG_BUILTIN_DTB_SOURCEis empty (for example, allmodconfig), it fails to build, like this: make[2]: *** No rule to make target 'arch/sh/boot/dts/.dtb.o', needed by 'arch/sh/boot/dts/built-in.o'. Stop.Surround obj-y with ifneq ... endif.I replaced $(CONFIG_USE_BUILTIN_DTB) with 'y' since this is alwaysthe case from the following code from arch/sh/Makefile: core-$(CONFIG_USE_BUILTIN_DTB) += arch/sh/boot/dts/Signed-off-by: Masahiro Yamada List of files: /linux-6.15/scripts/dtc/include-prefixes/sh/Makefile

74ce1896 - kbuild: clean up .dtb and .dtb.S patterns from top-level Makefile

Thu, 02 Nov 2017 02:51:25 +0000

kbuild: clean up *.dtb and *.dtb.S patterns from top-level MakefileWe need to add "clean-files" in Makfiles to clean up DT blobs, but weoften miss to do so.Since there are no source files that end with .dtb or .dtb.S, so wecan clean-up those files from the top-level Makefile.Signed-off-by: Masahiro Yamada Acked-by: Arnd Bergmann Signed-off-by: Rob Herring List of files: /linux-6.15/scripts/dtc/include-prefixes/sh/Makefile
