From befe7c123ee4546316bb9aa9952c0e2f7c0d9c48 Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Thu, 26 Sep 2013 09:42:27 +0800 Subject: powerpc/85xx: rename the corenet_ds.c to corenet_generic.c This file is also used by some RDB and QDS boards. So the name seems not so accurate. Rename it to corenet_generic.c. Also update the function names in this file according to the change.
