From 5f91925c89c39e77c170de9366ffa5144a8dd8ec Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 2 Apr 2008 00:45:00 +1100 Subject: [PATCH] [POWERPC] 4xx: Fix PESDRn_UTLSET1 register setup on 460EX/GT The patch fixes a bug, where the PESDRn_UTLSET1 register was setup wrongly resulting in a non working PCIe port 1. With this fix both PCIe ports work fine again.
