Fix it.

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.
