From 2fde99ee3120416251922282c364833473135765 Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Fri, 12 Mar 2021 22:41:43 +0100 Subject: m68k: add an interrupt controller A (generic) copy of the GLUE device we already have for q800 to use with the m68k-virt machine. The q800 one would disappear in the future as q800 uses actually the djMEMC controller.
