This one apparently contains changes compared to previous version. > --- > arch/arm/mach-exynos/Kconfig | 8 ++++++++ > arch/arm/mach-exynos/exynos.c | 1 + > arch/arm/mach-exynos/platsmp.c | 4 ++++ > arch/arm/plat-samsung/include/plat/cpu.h | 11 ++++++++++- > 4 files changed, 23 insertions(+), 1 deletion(-) > > diff --git a/arch/arm/mach-exynos/Kconfig b/arch/arm/mach-exynos/Kconfig > index 1602abc..79a3e85 100644 > --- a/arch/arm/mach-exynos/Kconfig > +++ b/arch/arm/mach-exynos/Kconfig > @@ -84,6 +84,14 @@ config SOC_EXYNOS5250 > help > Enable EXYNOS5250 SoC support > > +config SOC_EXYNOS5410 > + bool "SAMSUNG EXYNOS5410" > + default y > + depends on ARCH_EXYNOS5 > + select PM_GENERIC_DOMAINS if PM_RUNTIME > + help > + Enable EXYNOS5410 SoC support > + > config SOC_EXYNOS5420 > bool "SAMSUNG EXYNOS5420" > default y > diff --git a/arch/arm/mach-exynos/exynos.c b/arch/arm/mach-exynos/exynos.c > index e973ff5..12db6cf 100644 > --- a/arch/arm/mach-exynos/exynos.c > +++ b/arch/arm/mach-exynos/exynos.c > @@ -312,6 +312,7 @@ static char const *exynos_dt_compat[] __initconst = { > "samsung,exynos4412", > "samsung,exynos5", > "samsung,exynos5250", > + "samsung,exynos5410", AFAIK you don't need this change now, as you can boot using the generic Exynos5 compatible string just fine. > "samsung,exynos5420", > "samsung,exynos5440", > NULL > diff --git a/arch/arm/mach-exynos/platsmp.c b/arch/arm/mach-exynos/platsmp.c > index 78002c7..a95213d 100644 > --- a/arch/arm/mach-exynos/platsmp.c > +++ b/arch/arm/mach-exynos/platsmp.c > @@ -60,6 +60,8 @@ static inline void __iomem *cpu_boot_reg_base(void) > { > if (soc_is_exynos4210() && samsung_rev() == EXYNOS4210_REV_1_1) > return S5P_INFORM5; > + if (soc_is_exynos5410()) > + return sysram_ns_base_addr; This would suggest that instead you need to enable secure firmware support on your board, by adding respective firmware node to your dts. Tushar just sent a similar patch series for Exynos5420 [1].

The series I mentioned above also deals with bypassing adding of 4*cpu offset for Exynos5420. Seems like it might be also necessary for Exynos5410, however I will reply in that thread with the way I'd see this done. > else if (soc_is_exynos5420()) > boot_reg += 4; > return boot_reg; > diff --git a/arch/arm/plat-samsung/include/plat/cpu.h b/arch/arm/plat-samsung/include/plat/cpu.h > index 5992b8d..21db380 100644 > --- a/arch/arm/plat-samsung/include/plat/cpu.h > +++ b/arch/arm/plat-samsung/include/plat/cpu.h > @@ -49,6 +49,7 @@ extern unsigned long samsung_cpu_id; > #define EXYNOS4_CPU_MASK 0xFFFE0000 > > #define EXYNOS5250_SOC_ID 0x43520000 > +#define EXYNOS5410_SOC_ID 0xE5410000 > #define EXYNOS5420_SOC_ID 0xE5420000 > #define EXYNOS5440_SOC_ID 0xE5440000 > #define EXYNOS5_SOC_MASK 0xFFFFF000 > @@ -72,6 +73,7 @@ IS_SAMSUNG_CPU(exynos4210, EXYNOS4210_CPU_ID, EXYNOS4_CPU_MASK) > IS_SAMSUNG_CPU(exynos4212, EXYNOS4212_CPU_ID, EXYNOS4_CPU_MASK) > IS_SAMSUNG_CPU(exynos4412, EXYNOS4412_CPU_ID, EXYNOS4_CPU_MASK) > IS_SAMSUNG_CPU(exynos5250, EXYNOS5250_SOC_ID, EXYNOS5_SOC_MASK) > +IS_SAMSUNG_CPU(exynos5410, EXYNOS5410_SOC_ID, EXYNOS5_SOC_MASK) > IS_SAMSUNG_CPU(exynos5420, EXYNOS5420_SOC_ID, EXYNOS5_SOC_MASK) > IS_SAMSUNG_CPU(exynos5440, EXYNOS5440_SOC_ID, EXYNOS5_SOC_MASK) > > @@ -154,6 +156,12 @@ IS_SAMSUNG_CPU(exynos5440, EXYNOS5440_SOC_ID, EXYNOS5_SOC_MASK) > # define soc_is_exynos5250() 0 > #endif > > +#if defined(CONFIG_SOC_EXYNOS5410) > +# define soc_is_exynos5410() is_samsung_exynos5410() > +#else > +# define soc_is_exynos5410() 0 > +#endif > + > #if defined(CONFIG_SOC_EXYNOS5420) > # define soc_is_exynos5420() is_samsung_exynos5420() > #else > @@ -168,7 +176,8 @@ IS_SAMSUNG_CPU(exynos5440, EXYNOS5440_SOC_ID, EXYNOS5_SOC_MASK) > > #define soc_is_exynos4() (soc_is_exynos4210() || soc_is_exynos4212() || \ > soc_is_exynos4412()) > -#define soc_is_exynos5() (soc_is_exynos5250() || soc_is_exynos5420()) > +#define soc_is_exynos5() (soc_is_exynos5250() || soc_is_exynos5410() || \ > + soc_is_exynos5420()) After addressing the comments above, you won't need any changes to this file anymore (including all the soc_is_*() macros).
