[U-Boot] x86: SecureBoot: Bay Trail

Hi,

i'm implementing Secure Boot with U-Boot on a Intel Atom E3800 Series (Bay Trail) based Plattform.

I did manage to get the first boot stage (Initial Boot Block) verified by the Trusted Execution Engine, next i need to verify the "ramstage" as they call it.

Intel provides a manual on how to enable Secure Boot with coreboot in this manual they extract the "ramstage" from the coreboot.rom file via cbfs.

How can i get the equivalent for the coreboot-ramstage from U-Boot?

Best regards

Markus
