…non-secure world Add assign_dump_table_region() to notify TZ that the memory dump table region should be made accessible to AOP, via a self-contained SCM SMC call (QCOM_SCM_SVC_UTIL / QCOM_SCM_UTIL_DUMP_TABLE_ASSIGN). The SMC convention probe (__get_convention()) and dispatch helper are kept local to this driver rather than exported from qcom_scm, since only the register-argument SMC path is needed here. Wire it into mem_dump_alloc(), falling back to the IMEM-based dump table registration path if the SCM call fails. signed-off-by: Jie Gan <jie.gan@oss.qualcomm.com>
