From 1b0757eceddf037aad99ab59217a3a5c215e15d1 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Wed, 24 Oct 2012 02:36:15 +0000 Subject: PPC: remove dead boards (AMX860, c2mon, ETX094, IAD210, LANTEC, SCM) These boards have long reached EOL, and there has been no indication of any active users of such hardware for years. Get rid of the dead weight.
