This happened twice this week: - My proposed to change to rework the QCOM_SCM firmware symbol broke on ppc64 and others. - The cs_dsp firmware patch added device specific firmware loader into drivers/firmware, which broke on the same set of architectures. We should probably do the same thing for other subsystems as well, but fix this one first as this is a dependency for other patches getting merged.

I'd prefer to merge it along with the QCOM_SCM change through the soc tree, but that leaves the cirrus firmware broken unless we also merge it the same way (rather than through ASoC as it is now). Alternatively, we can try to find a different home for the Cirrus firmware to decouple the two problems. I'd argue that it's actually misplaced here, as drivers/firmware is meant for kernel code that interfaces with system firmware, not for device drivers to load their own firmware blobs from user space. --- arch/arm/Kconfig | 2 -- arch/arm64/Kconfig | 2 -- arch/ia64/Kconfig | 2 -- arch/mips/Kconfig | 2 -- arch/parisc/Kconfig | 2 -- arch/riscv/Kconfig | 2 -- arch/x86/Kconfig | 2 -- drivers/Kconfig | 2 ++ 8 files changed, 2 insertions(+), 14 deletions(-) diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index ad96f3dd7e83..194d10bbff9e 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -1993,8 +1993,6 @@ config ARCH_HIBERNATION_POSSIBLE endmenu -source "drivers/firmware/Kconfig" - if CRYPTO source "arch/arm/crypto/Kconfig" endif diff --git a/arch/arm64/Kconfig b/arch/arm64/Kconfig index ebb49585a63f..8749517482ae 100644 --- a/arch/arm64/Kconfig +++ b/arch/arm64/Kconfig @@ -1931,8 +1931,6 @@ source "drivers/cpufreq/Kconfig" endmenu -source "drivers/firmware/Kconfig" - source "drivers/acpi/Kconfig" source "arch/arm64/kvm/Kconfig" diff --git a/arch/ia64/Kconfig b/arch/ia64/Kconfig index 045792cde481..1e33666fa679 100644 --- a/arch/ia64/Kconfig +++ b/arch/ia64/Kconfig @@ -388,8 +388,6 @@ config CRASH_DUMP help Generate crash dump after being started by kexec. -source "drivers/firmware/Kconfig" - endmenu menu "Power management and ACPI options" diff --git a/arch/mips/Kconfig b/arch/mips/Kconfig index 771ca53af06d..6b8f591c5054 100644 --- a/arch/mips/Kconfig +++ b/arch/mips/Kconfig @@ -3316,8 +3316,6 @@ source "drivers/cpuidle/Kconfig" endmenu -source "drivers/firmware/Kconfig" - source "arch/mips/kvm/Kconfig" source "arch/mips/vdso/Kconfig" diff --git a/arch/parisc/Kconfig b/arch/parisc/Kconfig index 4742b6f169b7..27a8b49af11f 100644 --- a/arch/parisc/Kconfig +++ b/arch/parisc/Kconfig @@ -384,6 +384,4 @@ config KEXEC_FILE endmenu -source "drivers/firmware/Kconfig" - source "drivers/parisc/Kconfig" diff --git a/arch/riscv/Kconfig b/arch/riscv/Kconfig index 301a54233c7e..6a6fa9e976d5 100644 --- a/arch/riscv/Kconfig +++ b/arch/riscv/Kconfig @@ -561,5 +561,3 @@ menu "Power management options" source "kernel/power/Kconfig" endmenu - -source "drivers/firmware/Kconfig" diff --git a/arch/x86/Kconfig b/arch/x86/Kconfig index e5ba8afd29a0..5dcec5f13a82 100644 --- a/arch/x86/Kconfig +++ b/arch/x86/Kconfig @@ -2834,8 +2834,6 @@ config HAVE_ATOMIC_IOMAP def_bool y depends on X86_32 -source "drivers/firmware/Kconfig" - source "arch/x86/kvm/Kconfig" source "arch/x86/Kconfig.assembler" diff --git a/drivers/Kconfig b/drivers/Kconfig index 30d2db37cc87..0d399ddaa185 100644 --- a/drivers/Kconfig +++ b/drivers/Kconfig @@ -17,6 +17,8 @@ source "drivers/bus/Kconfig" source "drivers/connector/Kconfig" +source "drivers/firmware/Kconfig" + source "drivers/gnss/Kconfig" source "drivers/mtd/Kconfig" From patchwork Tue Sep 28 07:50:27 2021 Content-Type: text/plain;

Ideally we'd use a similar dependency here to what we have for QCOM_RPROC_COMMON, but that causes dependency loops from other things selecting QCOM_SCM. This appears to be an endless problem, so try something different this time: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement. According to my testing this still builds fine, and the QCOM platform selects this symbol already.
