Looking at the logs you've got, the final bios only have BIOS/coreboot and descriptor.bin, the GbE/ME areas are not used, I think as long as your enable the descripor.bin, it should be good enough.

Dear Sir.
Thank's your advise. It is very useful to me.
My work log is see below.

*The Flash Region 2~3 is (unused). Is it corrent?*
And descriptor.bin's content is see below.

*Is this descrptor.bin enought to support GbE interface?*
Thank you.
