Libreboot supports the Dell 3050 Micro and the Lenovo T480. I was wondering, since it requires the FSP blob, could it be a backdoor? Does anyone know how it works? Compared to the T440p and 9020, those boards are 100% free BIOS, but lack newer microcode updates.

By its limited scope of just initializing the chip, it seems a lot more benign than Intel ME, which would be a jucier target than the FSP. But no independent audit has been completed on it to my knowledge. Purism got started with an attempt to reverse-engineer it (legitimately without the leaked code!), but Intel told them to take it down, which is a bit troubling.
I wonder if anyone got the archive of that article.
Thank you!
