From 116bdc425c7e01e97cff2f3e6d0134511e8f13e3 Mon Sep 17 00:00:00 2001 From: Ishizaki Kou Date: Thu, 24 Apr 2008 19:25:16 +1000 Subject: [POWERPC] celleb: Move the files for celleb base support This moves the base code for celleb support into platforms/cell/. All files in this patch are used by celleb-beat and celleb-native commonly.
