• https://github.com/osresearch/heads/issues/134#issuecomment-368922440 documentation should be under wiki
• https://github.com/u-root/u-bmc/issues/133 for replacement of old an unmaintained openbmc code (part of funding path)
• Is the newer flashrom still working to flash the bmc to flash it from heads?
• No TPM2 14-1 pins boards avail? (prospection https://github.com/osresearch/heads/pull/893/)
• 16MB SPI: W25Q128FVSG SOP8 chip soldered on top of a SOP8 SO8 SOIC8 TO DIP8 adapter
