Did you set the following in your config file --> CONFIG_LEGACY_UART_MODE=y
Also have you setup all the proper fsp/ucode binaries that are commented out in the config file (just did a quick review):
#Sample settings for Denverton-NS FSP. #CONFIG_ADD_FSP_BINARIES=y #CONFIG_FSP_M_FILE="../intel/fsp/denverton_ns/DENVERTON-NS_FSP_M.fd" #CONFIG_FSP_S_FILE="../intel/fsp/denverton_ns/DENVERTON-NS_FSP_S.fd" #CONFIG_FSP_T_FILE="../intel/fsp/denverton_ns/DENVERTON-NS_FSP_T.fd" #CONFIG_FSP_CAR=y
#Sample settings for microcode definitions. #CONFIG_CPU_MICROCODE_HEADER_FILES="../intel/cpu/denverton_ns/microcode/microcode_blob.h" #CONFIG_CPU_MICROCODE_CBFS_EXTERNAL_HEADER=y
Unfortunately all my harcuvar work has also been on a fairly old tree of coreboot.
I'll give it a try on my Harcuvar if you don't make any progress, but it won't be until the weekend.
