Glue CPLD

The Glue CPLD on the Extreme Edge Server runs off management power and is
associated with the BMC and is powered anytime -48V power is present. It implements
these major functions:
 Monitor output of low-temperature thermal switch
 Enable BMC power under appropriate operating conditions
 Implement power-up timing sequence requirements for non-CPU power rails
 Supervision of non-CPU power rails

Enable on-board clocks when payload power is stable

 I
 Update configuration of the logic device via I
 Reset control
 BMC serial routing, routes 1 UART from each CPU to BMC

Control debug LEDs via registers
 Watchdog timer
 LPC slave interface connected to CPU1
 Implement status and control registers for SFP+ modules
