commit ca767f8729c52806a64419af18515480fa9e2c87 Author: Vadim Bendebury vbendeb@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.
