[U-Boot] Broadwell-DE bare metal

[vnktux]

Hi Simon,

Thanks for the info. I already have all the necessary blobs from the current working implementation with Coreboot + U-Boot: FPS, ME, Microcode, Flash Descriptor, VGA Rom.

To start porting I was planning to copy all the files of the board minnowmax and rename it with the name of our product. I saw that minnowmax use FSP 1.0 exactly like Broadwell-DE. I hope that helps.

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.
