The sbi_hsm_hart_started_mask() API should take one more parameter to allow caller specify domain under which started_mask is being generated. Further, the sbi_hsm_hart_started_mask() depends on sbi_hsm_hart_get_state() which also should return HART state under specified domain. This patch updates both sbi_hsm_hart_started_mask() and sbi_hsm_hart_get_state() as-per above. Signed-off-by: Anup Patel <anup.patel@wdc.com> Reviewed-by: Alistair Francis <alistair.francis@wdc.com>
