-Subject: [PATCH] smt: Make status and length volatile for mod_smt_memory
-
-There is an intermittent error on TF-A side when reading the mailbox.
-The error is due to the mailbox message length not matching the expectation:
- ASSERT: drivers/arm/css/scmi/scmi_pwr_dmn_proto.c:48
-
-This is due to a race between SCP writing the data and TF-A reading them.
-
-Effectively, the compiler seems to perform some minor optimisations with the
-local mod_smt_memory resulting in the expected writing sequence to be altered.
-This is seen in smt_respond().
-
-To remove such optimisations, force the length and status to be volatile.
-With this patch the sequence of writing into smt is restored and the error
-in TF-A disappears.
