I actually procrastinated the better part of my work day today documenting
the Marvell core types in the existing kernel documentation directory
and ended up with the patch below. ;-)
If you still remember some of the details of the ancient cores that were
not entirely clear to me, please have a look.

commit 6f8cedd5ba8ca52b3bc258244ce4a8927a7f12a8
Author: Arnd Bergmann <arnd@arndb.de>
Date: Fri Dec 11 15:49:13 2015 +0100
ARM: documentation: update Marvell product listing
I'm still getting confused regarding which core specifically
is used in which SoC, so I've added some more detail to the
Marvell README file. I got most of this from random sources
on the internet, so it's possible that some of the information
is wrong, but most of it should be pretty obvious.
There are a few remaining points I could not find out:
* The CPU core in Orion 88F6183
* The difference (if any) between PJ4B-MP and PJ4C
* The naming of Feroceon/Jolteon/Flareon/Sheeva/Mohawk/PJ1/PJ4
is still confusing, as they tend to overlap.

+CPU Cores
+---------

+The XScale cores were designed by Intel, and shipped by Marvell in the older
+PXA processors. Feroceon is a Marvell designed core that developed in-house,
+and that evolved into Sheeva. The XScale and Feroceon cores were phased out
+over time and replaced with Sheeva cores in later products, which subsequently
