config PS_TEST_NV_COUNTERS
    bool "Use the PS test NV counters"
    default y
    help
      Enables the virtual implementation of the PS NV counters interface in
      test/secure_fw/suites/ps/secure/nv_counters of the tf-m-tests repo,
      which emulates NV counters in RAM, and disables the hardware
      implementation of NV counters provided by the secure service. This flag is
      enabled by default, but has no effect when the secure regression test is
      disabled. This flag can be overridden to OFF when building the regression
      tests. In this case, the PS rollback protection test suite will not be
      built, as it relies on extra functionality provided by the virtual NV
      counters to simulate different rollback scenarios.

      The remainder of the PS test suites will run using the hardware NV
      counters. Please note that running the tests in this configuration will
      quickly increase the hardware NV counter values, which cannot be decreased
      again.

      Overriding this flag from its default value of OFF when not building the
      regression tests is not currently supported.
