18   -How to lock your code in cache in uClinux/blackfin
19   ---------------------------------------------------
20   -
21   -There are only a few steps required to lock your code into the cache.
22   -Currently you can lock the code by Way.
23   -
24   -Below are the interface provided for locking the cache.
25   -
26   -
27   -1. cache_grab_lock(int Ways);
28   -
29   -This function grab the lock for locking your code into the cache specified
30   -by Ways.
31   -
32   -
33   -2. cache_lock(int Ways);
34   -
35   -This function should be called after your critical code has been executed.
36   -Once the critical code exits, the code is now loaded into the cache. This
37   -function locks the code into the cache.
38   -
39   -
40   -So, the example sequence will be:
41   -
42   - cache_grab_lock(WAY0_L); /* Grab the lock */
43   -
44   - critical_code(); /* Execute the code of interest */
45   -
46   - cache_lock(WAY0_L); /* Lock the cache */
47   -
48   -Where WAY0_L signifies WAY0 locking.
