/*

 * SCT entry contains of the following parameters

 * uid: Unique id for the client's use case

 * slice_id: llcc slice id for each client

 * max_cap: The maximum capacity of the cache slice provided in KB

 * priority: Priority of the client used to select victim line for replacement

 * fixed_size: Determine of the slice has a fixed capacity

 * bonus_ways: Bonus ways to be used by any slice, bonus way is used only if

 *             it't not a reserved way.

 * res_ways: Reserved ways for the cache slice, the reserved ways cannot be used

 *           by any other client than the one its assigned to.

 * cache_mode: Each slice operates as a cache, this controls the mode of the

 *             slice normal or TCM

 * probe_target_ways: Determines what ways to probe for access hit. When

 *                    configured to 1 only bonus and reseved ways are probed.

 *                    when configured to 0 all ways in llcc are probed.

 * dis_cap_alloc: Disable capacity based allocation for a client

 * write_scid_en: Bit enables write cache support for a given scid.

 * retain_on_pc: If this bit is set and client has maitained active vote

 *               then the ways assigned to this client are not flushed on power

 *               collapse.

 * activate_on_init: Activate the slice immidiately after the SCT is programmed
