From 0be969a2d974971628fc4ed95834d22ecf0fd497 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 12 Sep 2014 14:06:50 +0100 Subject: hw/arm/virt: fix pl011 and pl031 irq flags The pl011 and pl031 devices both use level triggered interrupts, but the device tree we construct was incorrectly telling the kernel to configure the GIC to treat them as edge triggered. This meant that output from the pl011 would hang after a while.
