From 859b21a008ebcc7fd876f50738f63750d46b5296 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Fri, 24 Feb 2023 15:49:58 -0500 Subject: powerpc: drop PowerQUICC II Family ADS platform support 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 These 82xx platforms are two decades old, and originally made for a small group of industry related people in order to assist in new OEM board designs.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.
