Yes but at the time there was no FSP. I suspect now it would not be
needed.
What about booting times? How long it'll take to boot EFI -> U-Boot -> OS loader -> init process on x86?
My best guess at least/minimum 10s. Did anybody measure the booting time?
Thank you, Zoran

This is a true art of overkill... Really.
Full EFI (around 1 to 2 million lines of code: SEC, PEI, DXE phases,
with ME HECI involved, altogether) -> U-Boot -> YOCTO. Wow. ;-)

Hi all,
For my graduation project my company asked to use U-Boot as bare
metal boot-loader on one of their product. The product in an embedded board with a Xeon Broadwell-DE D-1527 Quad Core. 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.
The original U-Boot payload support was done with Broadwell-DE (I'm not sure which one though). It allows U-Boot to boot from EFI.
For what you want, yes you will need to obtain various binary blobs. Hopefully you can get the FSP from Intel, and with that the work required in U-Boot is probably not too large. Although I'm sure that the FSP API will have changed a little.
