I managed to fix things by adding to my defconfig:

CONFIG_USE_BLOBS=y
CONFIG_HAVE_IFD_BIN=y
CONFIG_HAVE_ME_BIN=y
CONFIG_FSP_M_FILE="3rdparty/blobs/mainboard/$(MAINBOARDDIR)/fspm.bin"
CONFIG_FSP_S_FILE="3rdparty/blobs/mainboard/$(MAINBOARDDIR)/fsps.bin"
CONFIG_CPU_UCODE_BINARIES="3rdparty/blobs/mainboard/$(MAINBOARDDIR)/cpu_
microcode_blob.bin"

Of course I had to create correct directory in blobs repository.

Thanks for help. I know see other issues in log that I have to deal
with, but I think I can deal with those now.

Best Regards,
