The MPC8272-ADS also supported other 82xx CPU variants, had 64MB RAM,
8MB flash, and like the 85xx ADS platforms, was on a fairly large PCB
in order to have space for breakout connectors for all the features.
These 82xx platforms are two decades old, and originally made for a
small group of industry related people in order to assist in new OEM
board designs. Given that, it makes sense to remove support today.
