[TF-M] MPU Fault Handler in the 'Test secure irq' test

Hello,

During my update to the new TFM version (after one month pause), occurs the MPU Fault Handler in the 'Test secure irq' regression test (TFM_ENABLE_IRQ_TEST is enabled).

The reason is that the test partition is defined as APP_ROT (non-privileged), but the test accesses to the NS memory region (dined as Privileged by default): spm_irq_test_1_prepare_test_scenario_internal(enum irq_test_scenario_t irq_test_scenario, struct irq_test_execution_data_t *execution_data) "execution_data" points to a global structure in NS RAM area provided by the NS test.

The workaround: Define the IRQ test partition as PSA_ROT (privileged). Is it OK?

Is this known issue?

Thanks, Andrej Butok
