From 647422868e48c9abd8ab85ad2a7de9161170ec89 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Sun, 13 Nov 2005 16:06:49 -0800 Subject: [PATCH] [PATCH] ppc32: Add support for handling PCI interrupts on MPC834x PCI expansion card The MPC8349 PIBs system has a expansion board with 6 PCI slots. We needed to update the IDSEL interrupt mapping for it to work properly. However, only PCI1 is supported as the first revision of this expansion board doesn't function properly for PCI2. For the time being we have zero'd out the entries for the IDSELs related to PCI2. When a functioning expansion board exists we can fix the table.
