From dc37a517739907accf78817778b56b6031e69e7f Mon Sep 17 00:00:00 2001
From: mark <mark@NetBSD.org>
Date: Sun, 22 Feb 1998 00:05:00 +0000
Subject: [PATCH] In the future we may want to branch somewhere other than zero
 when reseting the CPU. Rename the boot0() function to cpu_reset() and provide
 a variable to hold the cpu reset address.
