From da3601a5fa664c8d51383fe916d96bd4fbce84b8 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Fri, 22 May 2009 14:16:39 +1000 Subject: m68knommu: add support for second interrupt controller of ColdFire 5249 The ColdFire 5249 CPU has a second (compleletly different) interrupt controller. It is the only ColdFire CPU that has this type. It controlls GPIO interrupts amongst a number of interrupts from other internal peripherals. Add support code for it.
