From a572f83e7198eff99728335e697e9a0ef1e53a0c Mon Sep 17 00:00:00 2001 From: Rudolf Marek Date: Mon, 13 Apr 2009 17:57:44 +0000 Subject: Following patch adds necessary hooks and as well the compile time checks for ACPI suspend/resume. The memory cleared now is just the coreboot memory not the low memory.
