From da69582ce45d4302cb0265b56a65f0787603a29a Mon Sep 17 00:00:00 2001 From: Joseph Smith Date: Thu, 15 May 2008 13:44:33 +0000 Subject: This patch allows the RCA RM4100 to reboot. Upon rebooting in auto.c it detects if the memory is already initialized, if so it issues a hard reset through the southbridge.
