Yes but at the time there was no FSP. I suspect now it would not be needed.

The current boot-loader consist of Coreboot + U-Boot, but of course they want to get rid of Coreboot. I have almost no experience with U-Boot (Just with ARM processor a little bit) and so far I don't even know if it's possible or not to achieve the final goal. What I have understood is that I need the following binary blobs to work: fsp.bin, vga.bin, descriptor.bin, me.bin, microcode.bin. Is it true? Can somebody point me in the right direction because I am a little bit lost?  Plus I don't see many x86 boards implemented in the source code of U-Boot.
