Hi Nitin,
Harcuvar platform/Denverton soc was not fully updated for coreboot 4.11. We are working on that.
As a starting point you need to add two options to denverton_ns soc Kconfig file:
diff --git a/src/soc/intel/denverton_ns/Kconfig b/src/soc/intel/denverton_ns/Kconfig index cb3713d3b0..0d657cfc2d 100644 --- a/src/soc/intel/denverton_ns/Kconfig +++ b/src/soc/intel/denverton_ns/Kconfig @@ -32,6 +32,8 @@ config CPU_SPECIFIC_OPTIONS select SOC_INTEL_COMMON select SOC_INTEL_COMMON_RESET select PLATFORM_USES_FSP2_0 + select FSP_CAR + select SUPPORT_CPU_UCODE_IN_CBFS select C_ENVIRONMENT_BOOTBLOCK select IOAPIC select HAVE_SMI_HANDLER
