This change turns on the code which allows u-boot to add timestamps to the timestamp table created by coreboot. Since u-boot does not use the tsc_t like structure to represent HW counter readings, this structure is being replaced by 64 bit integer. The timestamp_init() function is now initializing the base timer value used by u-boot to calculate the HW counter increments. Timestamp facility is initialized as soon as the timestamp table pointer is found in the coreboot table. The u-boot generated timer events' ID will start at 1000 to clearly separate u-boot events from coreboot events in the timer trace.
