From 2892023fd422794bb82658dde3e8d489af2bdd55 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Thu, 17 Jan 2013 12:04:08 -0700 Subject: AGESA F15tn: Move callouts into northbridge wrapper There are currently too many things in the mainboard directories that are really more suited to being in the northbridge / southbridge wrappers. This is a start at moving some of those functions down into the wrappers. Move the bios callback functions into the northbridge/amd/agesa/family15tn directory from the mainboard directories. These can still be overridden by any mainboard just by updating the pointer in the callback table to point to a customized version of the function.
