Hi Zvika, In the case of a very limited number of chips, the IFD and GbE regions can be generated, and the ME region skipped entirely (see libreboot/ich9gen). For the others, some reverse engineering may be possible for the IFD and GbE regions but generating even a "me_cleaner" comparable region would require substantial reverse engineering, due to the obfuscation and protection measures in the ME.
Essentially these regions are not publicly documented and are probably covered under NDA, and in the case of the ME likely not available unless you're Intel yourself.
