From 261efc3f178c8c5b55d76208aee1f39ce247f723 Mon Sep 17 00:00:00 2001 From: Geoff Levand Date: Thu, 23 Nov 2006 00:46:57 +0100 Subject: [POWERPC] ps3: add lpar addressing Adds some needed bits for a config option PS3_USE_LPAR_ADDR that disables the PS3 lpar address translation mechanism. This is a currently needed workaround for limitations in the design of the generic cell spu support.
