commit 56c20fcc646838e17e44f2a90c14996315698643
Author: Vadim Bendebury 
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.
