From bd7e8d8d2b1d65e59dd45db6529c89f9173b7b20 Mon Sep 17 00:00:00 2001 From: Christian Gmeiner Date: Thu, 6 Jun 2013 14:37:49 +0200 Subject: AMD Northbridge LX: simplify get_top_of_ram() Get rid of not needed dependency to gliu0table. This change is needed to move get_top_of_ram() to raminit.c - as needed for EARLY_CBMEM_INIT. Boot tested on a Bachmann OT200.
