FSP reviews and mentions

• MrChromebox-4.20 firmware release is out
  1 project | /r/coreboot | 21 May 2023

  I tried to find in the Intel GitHub repo, but it's not there, and there's an unanswered question about it from you https://github.com/intel/FSP/issues/74

• AMD to move to open source firmware in 2026
  5 projects | /r/hardware | 6 May 2023

  There may be other protections to restrict SPI flash access for security reasons (so you might not be able to flash your custom firmware in the OS), but worst case you can use a HW flasher (or maybe USB flashback). Still, this doesn't address the elephant in the room - platform initialization code might be open-sourced, but that isn't everything. You'll still need to figure out the board-specific stuff (the Super I/O chip, chipset GPIOs, other peripherals, etc.). Using coreboot as an example, Intel provides the Firmware Support Package blob to handle platform initialization. I think AGESA is somewhat similar to this, though Intel publicly releases the binaries for use in coreboot/etc. Thanks to the FSP, coreboot has support for recent Intel chipsets. However, there is only support for two recent consumer boards: the MSI PRO Z690-A WiFi DDR4 and DDR5.

• AMA - Intel and Micro Center on the Intel 13th Gent Core Desktop Processors -October 21st 8:30am to 2:30 pm PDT

  May I ask why? I'm not talking about the source code, only about the final binaries. Intel already released many for previous platforms here https://github.com/intel/FSP. So I don't understand the security concerns you are referring to.

• Intel Confirms Alder Lake BIOS Source Code Leak, New Details Emerge
  3 projects | /r/hardware | 9 Oct 2022

  It's not entirely open source (it still depends on the FSP binaries), but Intel has released UEFI initialization code for older platforms. They also contribute platform support to coreboot (though this also depends on the FSP).

• Default blobs?
  1 project | /r/coreboot | 1 Sep 2022

  More recent Intel platforms (as of today, Haswell/Baytrail and newer) need some blobs to perform hardware initialization. There are two types of blobs: the non-redistributable MRC.bin and refcode blobs (which can be manually obtained from Chromebook recovery images), and FSP (binaries available in a GitHub repo). coreboot automatically includes FSP if the platform needs it and https://github.com/intel/FSP has the binaries.

• A Dream Come True: Running Coreboot On A Modern, Retail Desktop Motherboard
  1 project | /r/Qubes | 6 Jul 2022

  Intel publish some version of FSP in this repo. Unlike other blobs interface to FSP is documented and standarized in specification. There is even one related to security, which Qubes OS should probably consider as mendatory for certain hardware certification levels.
