Thanks guys! The dmbish() is not a huge deal. Just get a little nervous when i see barriers and don't completely understand why it is there. :)
Thanks Paul, Soby.
spm_response_*() currently cannot invoked by any secure partition since the responses array is in EL3 space. Is this not the case ? or is it the expectation that the responses array will be mapped to secure EL0 some time in the future? I don't see how a secure partition can invoke spm_response_* other than through an SMC, in which case we are already in EL3 context and dont require the dmbish(), as Paul pointed. I understand your argument for sprt_queue_*, since they are invoked by EL3 and the secure partition.

Thanks. Missed the lockless reader of the queue. Who is the lockless reader for spm_response_add() and spm_response_get()?
