From 3a30d2c34d9c287f49419b44c768ffb70764325c Mon Sep 17 00:00:00 2001 From: Anup Patel <anup.patel@wdc.com> Date: Sat, 19 Sep 2020 14:26:52 +0530 Subject: lib: sbi: Extend sbi_hsm_hart_start() for domains The sbi_hsm_hart_start() should consider the domain under which we are trying to start the HART. This will help ensure that HART A can start HART B only if both HARTs A and B belong to the same domain. We also have a special case when we bring-up boot HART of non-root domains in sbi_domain_finalize() where we should skip domain checks in sbi_hsm_hart_start(). To achieve this, sbi_hsm_hart_start() should do domain checks only when domain parameter is non-NULL. This patch extends sbi_hsm_hart_start() as-per above.
