Hi,
This issue is now understood. We'll submit a fix shortly.
Some background and rationale:
Interestingly the issue is masked with current compiler (clang 12.05) that CI and developer use which explains it's not been spotted during review. It exhibits when using a more recent compiler (here clang 13.0.1). With recent introduction of more hardened testing for multiple execution contexts in secure partitions,
SP secondary vCPUs use this entry point: https://git.trustedfirmware.org/hafnium/hafnium.git/tree/src/arch/aarch64/hf...
Above code misses enabling FP/SIMD access as done for VMs: https://git.trustedfirmware.org/hafnium/hafnium.git/tree/src/arch/aarch64/hf...
Regards, Olivier.

Notice the test_spmc.sh script looks broken on master (notifications vm to sp test fails). We'll investigate and hopefully provide a fix shortly.
