From 4edbe004b8b8c97900573218974191d2a2b77f1c Mon Sep 17 00:00:00 2001 From: Scott Duplichan Date: Wed, 13 Jul 2011 17:34:16 -0600 Subject: Move AMD SB800 early clock setup. Move the AMD SB800 early clock setup code that is needed for early serial port operation from mainboard/romstage.c to sb800/bootblock.c. This prevents code duplication and simplifies porting.
