I should have looked at this URL first: http://wiki.minnowboard.org/Coreboot That covers everything you need to know.
Your error is that your path to the IFD/TXE is wrong, so "dd" can't find it. Take a look at src/soc/intel/fsp_baytrail/Makefile.inc in the version of coreboot mentioned in the wiki. That version of coreboot made assumptions about the IFD and ME filename. The config item was called CONFIG_ME_PATH and it should be the folder that contains the files "descriptor.bin" and "txe.bin".
