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These 82xx platforms are two decades old, and originally made for a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.

Based on documentation revision dates, this MPC82xx pq2fads system
predates the MPC8272-ADS variant by about a year and only has 1/2
the amount of RAM (32MB) -- largely making it useless with a modern
v6.x kernel from today.
Similar to the MPC8272-ADS the pq2fads also supported other 82xx CPU
variants, had 8MB flash, and like the 8272 ADS platform, was on a fairly
large PCB in order to have space for breakout connectors for all 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These 82xx platforms are two decades old, and originally made for a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.
