The GbE is not activated on my Board. - coreboot

20 Jun 2016


      Dear Sir.
My ENV
EVB : ADI SG-2440
source : official coreboot
FSP : intel FSP 4.0
I was successfully build-up the coreboot and successfully boot-up my EVB.
But My EVB's GbE is not activated(not running.)
So, I was try to boot using the original OEM bios(from ADI). *This image 
is **act**vate the GbE*.
Another developer was same quetion to Coreboot communite. And He is 
resolved this issue.
https://www.coreboot.org/pipermail/coreboot/2015-January/079074.html
This guy's said that "Must add the descriptor.bin to coreboot.bin".
So, I was extract the descriptor.bin from ADI's coreboot.bin
And successfully attached the descriptor.bin to my coreboot.bin.
*oem_dumped.bin => ADI's default **coreboot.bin, This image are 
activated the GbE.*

I don't have a any idea for activate the GbE.
Please advise to me.
Thank you.
