From 8daf178168815e5af502a0fab343d23d7e1e4230 Mon Sep 17 00:00:00 2001 From: Thomas Monjalon Date: Thu, 15 Oct 2009 19:01:19 +0200 Subject: target-ppc: better support of e300 CPU core MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Declare HID2 register. Use high BATs for e300 (8 instead of 4). Fix index of high BATs registers. Before the fix, IBAT4-7 were overwriting IBAT0-3.
