a2faac39 - ARM: 9263/1: use .arch directives instead of assembler command line flags

Mon, 24 Oct 2022 19:44:41 +0000

ARM: 9263/1: use .arch directives instead of assembler command line flagsSimilar to commit a6c30873ee4a ("ARM: 8989/1: use .fpu assemblerdirectives instead of assembler arguments").GCC and GNU binutils support setting the "sub arch" via -march=,-Wa,-march, target function attribute, and .arch assembler directive.Clang was missing support for -Wa,-march=, but this was implemented inclang-13.The behavior of both GCC and Clang is toprefer -Wa,-march= over -march= for assembler and assembler-with-cppsources, but Clang will warn about the -march= being unused.clang: warning: argument unused during compilation: '-march=armv6k'[-Wunused-command-line-argument]Since most assembler is non-conditionally assembled with one sub arch(modulo arch/arm/delay-loop.S which conditionally is assembled as armv4based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which isconditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the.arch assembler directive.Add a few more instances found in compile testing as found by Arnd andNathan.Link: https://github.com/llvm/llvm-project/commit/1d51c699b9e2ebc5bcfdbe85c74cc871426333d4Link: https://bugs.llvm.org/show_bug.cgi?id=48894Link: https://github.com/ClangBuiltLinux/linux/issues/1195Link: https://github.com/ClangBuiltLinux/linux/issues/1315Suggested-by: Arnd Bergmann Suggested-by: Nathan Chancellor Signed-off-by: Arnd Bergmann Tested-by: Nathan Chancellor Signed-off-by: Nick Desaulniers Signed-off-by: Russell King (Oracle) List of files: /linux-6.15/arch/arm/mach-imx/Makefile

So, only somedead left-over in Kconfig and Makefile remains.Remove this remaining left-over.This issue was identified with ./scripts/checkkconfigsymbols.py,which warns on references to the non-existing configsMACH_MX{27,31,35}_3DS in ./arch/arm/mach-imx/Kconfig.Signed-off-by: Lukas Bulwahn Reviewed-by: Arnd Bergmann Signed-off-by: Shawn Guo List of files: /linux-6.15/arch/arm/mach-imx/Makefile

e34645f4 - ARM: imx: add smp support for imx7d

ARM: imx: add smp support for imx7dAdd SMP support for i.MX7D, including CPU hotplug support, forsystems where TFA is not present.The motivation for bringing up the second i.MX7D core inside the kernelis that legacy vendor bootloaders usually do not implement PSCI support.This is a significant blocker for systems in the field that are running oldbootloader versions to upgrade to a modern mainline kernel version, as onlyone CPU of the i.MX7D would be brought up.Bring up the second i.MX7D core inside the kernel to make the migrationpath to mainline kernel easier for the existing iMX7D users.Signed-off-by: Anson Huang Signed-off-by: Arulpandiyan Vadivel # Fix merge conflictsSigned-off-by: Leonard Crestez Signed-off-by: Marek Vasut # heavy cleanupSigned-off-by: Fabio Estevam Signed-off-by: Shawn Guo List of files: /linux-6.15/arch/arm/mach-imx/Makefile

512a928a - ARM: imx: build v7_cpu_resume() unconditionally

Thu, 16 Jan 2020 14:18:49 +0000

ARM: imx: build v7_cpu_resume() unconditionallyThis function is not only needed by the platform suspend code, but is alsoreused as the CPU resume function when the ARM cores can be powered downcompletely in deep idle, which is the case on i.MX6SX and i.MX6UL(L).Providing the static inline stub whenever CONFIG_SUSPEND is disabled meansthat those platforms will hang on resume from cpuidle if suspend is disabled.So there are two problems: - The static inline stub masks the linker error - The function is not available where neededFix both by just building the function unconditionally, whenCONFIG_SOC_IMX6 is enabled. The actual code is three instructions long,so it's arguably ok to just leave it in for all i.MX6 kernel configurations.Fixes: 05136f0897b5 ("ARM: imx: support arm power off in cpuidle for i.mx6sx")Signed-off-by: Lucas Stach Signed-off-by: Ahmad Fatoum Signed-off-by: Rouven Czerwinski Signed-off-by: Shawn Guo List of files: /linux-6.15/arch/arm/mach-imx/Makefile

ARM: imx: add initial support for imx7ulpThe i.MX 7ULP family of processors features NXP's advanced implementationof the Arm Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2DGraphics Processing Units (GPUs).This patch aims to add an initial support for imx7ulp. Note that we needconfigure power mode to Partial Stop mode 3 with system/bus clock enabledfirst as the default enabled STOP mode will gate off system/bus clock whenexecute WFI in MX7ULP SoC.And there's still no MXC_CPU_IMX7ULP IDs read from register as ULP has noanatop as before.
