Hi Brian,
We built secure world TF-M test for AN521 platform:
``` cmake -S spe -B build_spe -DTFM_PLATFORM=arm/mps2/an521 \ -DCONFIG_TFM_SOURCE_PATH="$TFM_SOURCE_DIR" \ -DCMAKE_BUILD_TYPE=Debug \ -DTEST_S=ON -DTEST_NS=OFF ```
We ran this test on a FVP model and stepped through `tfm_attest_test_1001`. Please find attached a screenshot of the call stack.
Function in `attest_core` (in the Attestation partition) invokes function in the `tfm_crypto_api`. This request is routed by the Secure Partition Manager (SPM) into the Crypto partition via `psa_call()`.

Is my configuration valid? How should it work?
Any time you call a function across partitions, regardless of isolation level, the SPM forwards it to the target partition using `psa_call()`
Best regards, Mudit Sharma
