	-  Instruction and Data cache Invalidation Routines, when flushing the
	   same is not required.
		_icache_invalidate();
		_dcache_invalidate();

	Also, for invalidating the entire instruction and data cache, the below
	routines are provided (another method for invalidation, refer page no 267 and 287 of
	ADSP-BF533 Hardware Reference manual)

		invalidate_entire_dcache();
		invalidate_entire_icache();

	-External Flushing of Instruction and data cache routines.

		flush_data_cache();

	- Internal Flushing of Instruction and Data Cache.

		icplb_flush();
		dcplb_flush();

	- Locking the cache.

		cache_grab_lock();
		cache_lock();

	Please refer linux-2.6.x/Documentation/blackfin/cache-lock.txt for how to
	lock the cache.

	Locking the cache is optional feature.
