Hi,

Looks like for this SoC turbo state is not available, so try the following
(enable speedstep regardless if turbo state is available or not, as you
need speedstep!) :

--- a/src/soc/intel/denverton_ns/cpu.c
+++ b/src/soc/intel/denverton_ns/cpu.c
@@ -71,11 +71,11 @@ static void denverton_core_init(struct device *cpu)
        enable_turbo();

/* Enable speed step. */
-       if (get_turbo_state() == TURBO_ENABLED) {
+//     if (get_turbo_state() == TURBO_ENABLED) {
                msr = rdmsr(IA32_MISC_ENABLE);
                msr.lo |= SPEED_STEP_ENABLE_BIT;
                wrmsr(IA32_MISC_ENABLE, msr);
-       }
+//     }
 }
