From 2d853bb58740d575c1bbcc1d29e92654069b11d9 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Tue, 17 Mar 2009 14:39:25 +0000 Subject: This patch adds "high coreboot table support" to coreboot version 2 Some bootloaders seem to overwrite memory starting at 0x600, thus destroying the coreboot table integrity, rendering the table useless. By moving the table to the high tables area (if it's activated), this problem is fixed. In order to move the table, a 40 bytes mini coreboot table with a single sub table is placed at 0x500/0x530 that points to the real coreboot table. This is comparable to the ACPI RSDT or the MP floating table. This patch also adds "table forward" support to flashrom and nvramtool. Corresponding to flashrom svn r421 and coreboot v2 svn r4012.
