At the face of it, there is an issue. Could I ask you to post this on the mailing list as I think this discussion may be of interest to wider community ?

Are you thinking something similar to measured boot ?
The TF-A implements what is called verified boot. Found a good description for difference between verified and measured boot here:

The Cryptocell variant supported by TF-A is CC-712 which only has support for RSA 2048.

Ah, You are right. Having taken a look at it again, yes, the SP-> SPM communication is register based and this spm_response_add() is invoked by SPM to push to a buffer within EL3 (its not a shared buffer between different ELs). I suspect the shared buffer primitives were written with shared buffer scenario in mind and the current prototype implementation does not optimize it for the case when the buffer is within EL3.
Who is the lockless reader for spm_response_add() and spm_response_get()?
