Dear Sir.



My Purpose is extract "Intel fsp.bin" from bios image.

First, (I was know that get possible "Intel fsp.bin" from Intel website. and already download It is.)



This time i have a some bios image.



This one is "ADI_RCCVE-01.00.00.08.rom". It is get from ADI.

Another one is "BIOS.bin". It is dump from Intel CRB.

This image's are perfectly support all function. ex) GbE, PCIe, spi flash



I was download the coreboot source from official coreboot git.

And build this source code, It is done.

And attach the "Intel fsp.bin" and "descriptor.bin" to my coreboot image(It is a "official coreboot source").



But occured the some problem.

First. Not enable all PCIe port. But was resolved, I was modify the fsp.bin used by BCT.

Second. Can't access spi flash used by "flashrom" utility. this util can't found the spi flash on my board.



But, If i use the "ADI_RCCVE-01.00.00.08.rom" and "Intel CRB's bios imge" on my board, can access the spi flash memory used by "flashrom" utility.



So, I want to extract "Intel FSP.bin" and "descriptor.bin" from "ADI_RCCVE-01.00.00.08.rom" and "Intel CRB's bios imge".



I was success extract the "descriptor.bin"

But fail the extract "Intel fsp.bin".



Could help to me?



Thank you.
