> +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.
