The get_bl_mem_params_node() function could return NULL. Add asserts to check the return value is not NULL. This corrects coverity issues: pager_mem_params = get_bl_mem_params_node(BL32_EXTRA1_IMAGE_ID); >>> CID 378360: (NULL_RETURNS) >>> Dereferencing "pager_mem_params", which is known to be "NULL". paged_mem_params = get_bl_mem_params_node(BL32_EXTRA2_IMAGE_ID); >>> CID 378360: (NULL_RETURNS) >>> Dereferencing "paged_mem_params", which is known to be "NULL". tos_fw_mem_params = get_bl_mem_params_node(TOS_FW_CONFIG_ID); >>> CID 378360: (NULL_RETURNS) >>> Dereferencing "tos_fw_mem_params", which is known to be "NULL". Do the same for other occurrences of get_bl_mem_params_node() return not checked, in the functions plat_get_bl_image_load_info() and bl2_plat_handle_pre_image_load().
