332 * TF_TCAM_TBL_TYPE_WC_TCAM_LOW.
334 * The user will allocate and free entries from either of these pools to obtain
335 * WC_TCAM entry offsets. For the WC_TCAM_HI/LO management, alloc/free is done
336 * using the tf_alloc_tcam_entry()/tf_free_tcam_entry() APIs for the shared
339 * The use case for this feature is so that applications can have a shared
340 * session and use the TF core to allocate/set/free entries within a given
341 * region of the WC_TCAM within the shared session. Application A only writes
342 * to the LOW region for example and Application B only writes to the HIGH
343 * region during normal operation. After Application A goes down, Application
344 * B may decide to overwrite the LOW region with the HIGH region's entries
345 * and switch to the low region.
347 * For other TCAM types in the shared session, no alloc/free operations are
348 * permitted. Only set should be used for other TCAM table types after getting
349 * the range as provided by the tf_get_resource_info() API.
