Valentin Longchamp - April 8, 2011, 12:47 p.m.
From: Holger Brunck <holger.brunck@keymile.com>

This patch rename mgcoge2ne board support to mgcoge3ne.
The board is similar to mgcoge. The difference is that
a NUMONYX flash is used and a larger SDRAM (256MB).
Also introduce CONFIG_KM_82XX to collect ppc82xx common
settings.
