2672031b - riscv: dts: Move BUILTIN_DTB_SOURCE to common Kconfig

Wed, 28 Feb 2024 08:52:54 +0000

riscv: dts: Move BUILTIN_DTB_SOURCE to common KconfigThe BUILTIN_DTB_SOURCE was only configured for K210 before. SinceSOC_BUILTIN_DTB_DECLARE was removed at commit d5805af9fe9f ("riscv: Fixbuiltin DTB handling") from patch [1], the kernel cannot choose one of thedtbs from then on and always take the first one dtb to use. Then, anothercommit 0ddd7eaffa64 ("riscv: Fix BUILTIN_DTB for sifive and microchip soc")from patch [2] supports BUILTIN_DTB_SOURCE for other SoCs. However, thisfeature will only work if the Kconfig we use links the dtb we expected inthe first place as mentioned in the thread [3]. Thus, a configBUILTIN_DTB_SOURCE is needed for all SoCs to choose one dtb to use.For some considerations, this patch also removes default y if XIP_KERNELfor BUILTIN_DTB, as this requires setting a proper dtb to use on theBUILTIN_DTB_SOURCE, else the kernel with XIP but does not setBUILTIN_DTB_SOURCE or unselect BUILTIN_DTB will not boot.Also, this patch removes the default dtb string for k210 from Kconfig tonommu_k210_defconfig and nommu_k210_sdcard_defconfig to avoid complexKconfig settings for other SoCs in the future.[1] https://lore.kernel.org/linux-riscv/20201208073355.40828-5-damien.lemoal@wdc.com/[2] https://lore.kernel.org/linux-riscv/20210604120639.1447869-1-alex@ghiti.fr/[3] https://lore.kernel.org/linux-riscv/CAK7LNATt_56mO2Le4v4EnPnAfd3gC8S_Sm5-GCsfa=qXy=8Lrg@mail.gmail.com/Signed-off-by: Yangyu Chen Reviewed-by: Conor Dooley Acked-by: Palmer Dabbelt Signed-off-by: Conor Dooley List of files: /linux-6.15/scripts/dtc/include-prefixes/riscv/canaan/Makefile

19ba9cf7 - RISC-V: kbuild: convert all use of SOC_FOO to ARCH_FOO

Sun, 20 Nov 2022 21:34:44 +0000

RISC-V: kbuild: convert all use of SOC_FOO to ARCH_FOOConvert all non user visible use of SOC_FOO symbols to their ARCH_FOOvariants. The canaan DTs are an outlier in that they're gated at thedirectory and the file level. Drop the directory level gating while weare swapping the symbol names over.Signed-off-by: Conor Dooley List of files: /linux-6.15/scripts/dtc/include-prefixes/riscv/canaan/Makefile

riscv: dts: canaan: build all devicetress if SOC_CANAANTesting & checking the Canaan devicetrees is inconvenient as only thedevicetree corresponding to SOC_CANAAN_K210_DTB_BUILTIN will be built.Change the Makefile so that all devicetrees are built by default ifSOC_CANAAN but only the one specified by SOC_CANAAN_K210_DTB_BUILTINgets built as an object.Signed-off-by: Conor Dooley Link: https://lore.kernel.org/r/20220705215213.1802496-14-mail@conchuod.ieSigned-off-by: Palmer Dabbelt List of files: /linux-6.15/scripts/dtc/include-prefixes/riscv/canaan/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/riscv/canaan/Makefile
