From f5fba9d27f14603dc7f85779e7b7362fb1cfcbd8 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 21 Jan 2013 15:53:55 +0000 Subject: PPC: e500: Select MPIC v4.2 on ppce500 platform The compatible string is changed to fsl,mpic on all e500 platforms, to advertise the existence of BRR1. This matches what the device tree will have on real hardware. With MPIC v4.2 max_cpu can be increased from 15 to 32.
