From ef50d6c06ece74fb17e8d7510e62cad9df8b810d Mon Sep 17 00:00:00 2001
From: Kumar Gala <galak@kernel.crashing.org>
Date: Tue, 12 Aug 2008 11:14:19 -0500
Subject: mpc85xx: Add support for the MPC8536

The MPC8536 Adds SDHC and SATA controllers to the PQ3 family.  We
also have SERDES init code for the 8536.

From 9cff4448a9cb882defe6c8bde73b77fc0c636799 Mon Sep 17 00:00:00 2001
From: Kumar Gala <galak@kernel.crashing.org>
Date: Tue, 19 Aug 2008 14:46:36 -0500
Subject: mpc85xx: remove redudant code with lib_ppc/interrupts.c

For some reason we duplicated the majority of code in lib_ppc/interrupts.c
not show how that happened, but there is no good reason for it.

Use the interrupt_init_cpu() and timer_interrupt_cpu() since its why
they exist.
