This patch adds "high coreboot table support" to coreboot version 2

Browse Source 
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.
