Facebook Monolith

This page describes how to run coreboot on the Facebook Monolith.

Please note: the coreboot implementation for this boards is in its Alpha state and isn't fully tested yet.

Required blobs

This board currently requires: fsp blobs 3rdparty/fsp/KabylakeFspBinPkg/Fsp_M.fd 3rdparty/fsp/KabylakeFspBinPkg/Fsp_S.fd

Microcode 3rdparty/intel-microcode/intel-ucode

Flashing coreboot

Internal programming

The SPI flash can be accessed using flashrom.

External programming

The system has an internal flash chip which is a 16 MiB soldered SOIC-8 chip. Specifically, it's a Winbond W25Q128JVSIQ (3.3V).

The system has an external flash chip which is a 16 MiB soldered SOIC-8 chip. Specifically, it's a Winbond W25Q128JVSIM (3.3V).

Flashing of these devices is very difficult, disassembling the system destroys the cooling solution. Wires need to be connected to be able to flash using an external programmer.

Known issues

  • None

Untested

  • Hardware monitor
  • SDIO
  • Full Embedded Controller support
  • eMMC
  • SATA

Working

  • USB
  • Gigabit Ethernet
  • Graphics (Using FSP GOP)
  • flashrom
  • PCIe
  • EC serial port
  • SMBus
  • Initialization with FSP
  • SeaBIOS payload (commit a5cab58e9a3fb6e168aba919c5669bea406573b4)
  • TianoCore payload (commit a5cab58e9a3fb6e168aba919c5669bea406573b4)

All of the above has been briefly tested by booting Linux from the TianoCore payload. SeaBios has been checked to the extend that it runs to the boot selection and provides display output.
