From 3e7b6c1f2db5ec31f9e7dbc3e0cbca602167a46a Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 2 Sep 2009 09:03:08 -0500 Subject: ppc/8xxx: Refactor code to determine if PCI is enabled & agent/host Refactor the code into a simple bitmask lookup table that determines if a given PCI controller is enabled and if its in host/root-complex or agent/end-point mode. Each processor in the PQ3/MPC86xx family specified different encodings for the cfg_host_agt[] and cfg_IO_ports[] boot strapping signals.
