From 0531d7b36b9894b60ba9c0633993d49a813555ff Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Fri, 1 May 2009 17:22:36 +1000 Subject: [PATCH] m68knommu: complete interrupt controller code for the 68360 CPU Define the interrupt controller structures along with the interrupt controller code for the 68360 CPU. This brings the interrupt setup and control into one place for this CPU family.
