This 2 MB memory is used by firmware for the number of peers. This number of peer is sent from host to firmware during WMI init command. For single-phy the number of peers sent is TARGET_NUM_PEERS_SINGLE = 529 (512 + 17). While for split-phy number of peers sent to firmware is TARGET_NUM_PEERS_DBS = 2 *(512 + 17) = 1058. With this 1058 number of peers firmware is unable to allocate memory in 2 MB segment and firmware crash is observed. Hence, fix this firmware crash by reducing the number of stations TARGET_NUM_STATIONS for split-phy.
