This region is used to store the timestamps from bootblock and verstage when cbmem is not yet initialized. Once cbmem is setup, the timestamps from this region can be retrieved and filled up properly in cbmem. In order to achieve this a new Kconfig option is introduced HAS_TIMESTAMP_REGION. This is to maintain compatbility with older boards which do not use this region.
