   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.
