U-Boot now has dcache turned on. This requires cache flushing to be performed before executing smc instrution. There are calls which are made to TZ with huge buffer (such as kernel image for authentication). Flushing and invalidating by address for such huge buffer will have a performance impact, as the size of buffer is vastly bigger than the cache size itself. Hence performing a flush of the entire cache as opposed to performing cache flush with a start and end address.
