This describes the story of trying to get the Pi to shutdown and reboot using a single power-button

Findings:

• gpio-shutdown interferes with I2C pin, we need to either move gpio-shutdown or i2c to different pins
• GLOBAL_EN does not seem to be useful to send a halt signal, shorting it to ground is equivalent to disconnecting the power (somehow) and thus will allow it to boot up, and hard-reset but thats it

Things modded:

• Installed the rpi-eeprom package documentation from Rpi themselves here

   rpi-eeprom-config
  
   To edit it and apply the updates to latest EEPROM release:
   sudo -E rpi-eeprom-config --edit```
