Hello Masanori, sorry for the late reply, I guess I could have saved you from some confusion.

Yes, coreboot's microcode should be up to date. However, in your log, it never tries to apply the update, it seems (it should tell something about the `cpu_microcode_blob.bin`). I also can't find any call in the current source that would try to update microcode, so this might be a recent regression. If anybody wants to look into this, one clue so far: in `src/cpu/ intel/model_1067x/mp_init.c` a `.get_microcode_info` pointer seems to be missing in the `struct mp_ops`. Also, the microcode should be updated once in advance for the BSP. This could be done early in the bootblock (as it is for `cpu/intel/model_206ax/`) or later, e.g. right before running mp_init_with_smm(). Nico
