-How to lock your code in cache in uClinux/blackfin
---------------------------------------------------
-
-There are only a few steps required to lock your code into the cache.
-Currently you can lock the code by Way.
-
-Below are the interface provided for locking the cache.
-
-
-1. cache_grab_lock(int Ways);
-
-This function grab the lock for locking your code into the cache specified
-by Ways.
-
-
-2. cache_lock(int Ways);
-
-This function should be called after your critical code has been executed.
-Once the critical code exits, the code is now loaded into the cache. This
-function locks the code into the cache.
-
-
-So, the example sequence will be:
-
- cache_grab_lock(WAY0_L); /* Grab the lock */
-
- critical_code(); /* Execute the code of interest */
-
- cache_lock(WAY0_L); /* Lock the cache */
-
-Where WAY0_L signifies WAY0 locking.
