From dec99558b9ea75a37940d07f41a3565a50b54ad1 Mon Sep 17 00:00:00 2001 From: Rafal Jaworowski Date: Tue, 31 Jul 2007 18:19:54 +0200 Subject: [PATCH] [ppc4xx] Separate settings for PCIe bus numbering on 440SPe rev.A This brings back separate settings for PCIe bus numbers depending on chip revision, which got eliminated in 2b393b0f0af8402ef43b25c1968bfd29714ddffa commit. 440SPe rev. A does NOT work properly with the same settings as for the rev. B (no devices are seen on the bus during enumeration).
