We would need to support versioning of SST FS data and also have mechanisms to detect if the flash is clean or in consistent state.

soby-mathew added a comment to T692: AN521 FVP soft reset via AIRCR does not reset MPC / PPC / MPU during PSA FF test.

This is an issue on FVP. It will case the system cannot boot up after a warm reset. So as a workaround, we have to skip BL2 when testing.

soby-mathew added a comment to T561: Update the TFM Crypto Service to use the mbedCrypto v2.0.

Yes, the mbed-crypto tag 3.1.0 adds these 2 new APIs whereas the version TF-M currently supports is 3.0.1. I intend to catch up once again in a month's time and hopefully by then mbed-crypto will have added more functions which can be utilized.

Hi vivina,
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:

soby-mathew added a comment to T334: Barrier in sprt_queue.c.

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.
