commit 56c20fcc646838e17e44f2a90c14996315698643
Author: Vadim Bendebury <vbendeb at chromium.org>
Date: Fri Sep 23 09:56:11 2011 -0700
Add timestamp table pointer to the coreboot table.
This change exports the timestamp table pointer through coreboot
table to make it possible for u-boot to add timestamps to the
table.
Inclusion of cbmem.h allows to drop external declarations in
coreboot_table.c.
