Subject: [PATCH 12/28] 8xx: Fix CONFIG_PIN_TLB.
Date: Mon, 17 Sep 2007 11:57:41 -0500 [thread overview]
Message-ID: <20070917165741.GL6563@loki.buserror.net> (raw)
In-Reply-To: <20070917165643.GA6545@loki.buserror.net>
1. Move CONSISTENT_START on 8xx so that it doesn't overlap the IMMR mapping.
2. The wrong register was being loaded into SPRN_MD_RPN.
