From 9858ee8ac52117cb38d7ef79b4db3382ea465a2a Mon Sep 17 00:00:00 2001 From: Ishizaki Kou Date: Tue, 4 Dec 2007 19:38:24 +1100 Subject: [PATCH] [POWERPC] celleb: Add support for native CBE This adds support for native CBE on Celleb, that is, without the BEAT hypervisor. Many codes in platforms/cell/ are used in native CBE environment.
