[PATCH] arm: Add basic support for new Marvell Armada SoC family

Personally, my view is leave it alone and just add a new machine
directory.

Pushing items around doesn't really help the amount of code in the
kernel, the organisation does not add more than a line or two to the
Makefiles.

It does however make it easier to see where the same code has been
cut/paste. There is some stuff in the various Orion mach- directories
which is repeated 4 times. The Armada XP port wanted to add a 5th
copy. All this repeated code needs to be put into plat-orion.
