[This RFC is proposed for v6.4 and hence is based off linux-next.]

This series removes support for two PowerQUICC II (MPC82xx) Freescale
processor family evaluation boards that were added to the kernel in
approximately the 2003 era.

I couldn't easily find a reference picture, but there are line art
sketches in the various manuals still available[1,2].  In any case,
we've got one system with 32MB RAM and the other with 64MB.  CPU speeds
are also what one would expect for twenty year old platforms.

Again, this only removes evaluation platforms.  There are still a couple
MPC82xx OEM platforms remaining in the kernel.  But given that they are
similar in age and similarly resource constrained, they probably should
be near the top of the removal consideration list once all the evaluation
board support removals are in.

For comparison, in v2.6.27 (2008, 917f0af9e5a9) the WR SBC8260 support
was implicitly retired by not being carried through the ppc --> powerpc
device tree transition of that era.

Paul.
