| LLCC (Last Level Cache Controller) provides last level of cache memory in SOC, |
| that can be shared by multiple clients. Clients here are different cores in the |
| SOC, the idea is to minimize the local caches at the clients and migrate to |
| common pool of memory. Cache memory is divided into partitions called slices |
| which are assigned to clients. Clients can query the slice details, activate |
| and deactivate them. |
