I think this might break others, see drivers/firmware/psci.c Regards, Peng. > > Signed-off-by: Oleksandr Andrushchenko > <oleksandr_andrushche...@epam.com> > Signed-off-by: Anastasiia Lukianenko <anastasiia_lukiane...@epam.com> > Suggested-by: Volodymyr Babchuk <volodymyr_babc...@epam.com> > --- > arch/arm/Kconfig | 1 - > arch/arm/cpu/armv8/Kconfig | 2 ++ > 2 files changed, 2 insertions(+), 1 deletion(-) > > diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index > 54d65f8488..e9ad716aaa 100644 > --- a/arch/arm/Kconfig > +++ b/arch/arm/Kconfig > @@ -387,7 +387,6 @@ config SYS_ARCH_TIMER config ARM_SMCCC > bool "Support for ARM SMC Calling Convention (SMCCC)" > depends on CPU_V7A || ARM64 > - select ARM_PSCI_FW > help > Say Y here if you want to enable ARM SMC Calling Convention. > This should be enabled if U-Boot needs to communicate with system > diff --git a/arch/arm/cpu/armv8/Kconfig b/arch/arm/cpu/armv8/Kconfig > index 3655990772..c8727f4175 100644 > --- a/arch/arm/cpu/armv8/Kconfig > +++ b/arch/arm/cpu/armv8/Kconfig > @@ -103,6 +103,8 @@ config PSCI_RESET > bool "Use PSCI for reset and shutdown" > default y > select ARM_SMCCC if OF_CONTROL > + select ARM_PSCI_FW if DM > + > depends on !ARCH_EXYNOS7 && !ARCH_BCM283X && \ > !TARGET_LS2080A_SIMU && !TARGET_LS2080AQDS && \ > !TARGET_LS2080ARDB && !TARGET_LS2080A_EMU && \ > -- > 2.17.1
