From 7edb1f7b86e31a21253fc89bd2bebf7d20ed36a5 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 30 May 2014 17:45:03 +0900 Subject: [PATCH] powerpc: debris: remove orphan board This board has been orphan for a while. (Emails to its maintainer have been bouncing.) Because MPC82xx family is old enough, nobody would pick up the maintainership on it.
