[Qemu-devel] [PATCH] sun4m: fix slavio sysctrl and led register sizes


From: Mark Cave-Ayland
Subject: [Qemu-devel] [PATCH] sun4m: fix slavio sysctrl and led register sizes
Date: Thu, 2 Apr 2015 16:09:30 +0100

These were being incorrectly declared as MISC_SIZE (1 byte) rather than
4 bytes and 2 bytes respectively. As a result accesses clamped to the
real register size would unexpectedly fail.
