This is also why you need to add RMV7_BOOT_SEC_DEFAULT=y to your defconfig to get things to work. We will need to figure out SMP support later for now just leave these out. > + > config MACH_SUN9I > bool "sun9i (Allwinner A80)" > select CPU_V7 > @@ -78,7 +87,7 @@ endchoice > # The sun8i SoCs share a lot, this helps to avoid a lot of "if A23 || A33" > config MACH_SUN8I > bool > - default y if MACH_SUN8I_A23 || MACH_SUN8I_A33 > + default y if MACH_SUN8I_A23 || MACH_SUN8I_A33 || MACH_SUN8I_A83T > > > config DRAM_CLK > diff --git a/include/configs/sun8i.h b/include/configs/sun8i.h > index 4fc6365..c139e0a 100644 > --- a/include/configs/sun8i.h > +++ b/include/configs/sun8i.h > @@ -25,6 +25,8 @@ > #define CONFIG_ARMV7_PSCI_NR_CPUS 2 > #elif defined(CONFIG_MACH_SUN8I_A33) > #define CONFIG_ARMV7_PSCI_NR_CPUS 4 > +#elif defined(CONFIG_MACH_SUN8I_A83T) > +#define CONFIG_ARMV7_PSCI_NR_CPUS 8 > #else > #error Unsupported sun8i variant > #endif > And this can be dropped too then.
