- * This model is mainly intended for testing purposes and doesn't fit to any
- * real hardware. On the one hand it provides a control register (R_CTRL) on
- * the other hand it supports the lm32 tests.
- *
- * A write to the control register causes a system shutdown.
- * Tests first write the pointer to a test name to the test name register
- * (R_TESTNAME) and then write a zero to the pass/fail register (R_PASSFAIL) if
- * the test is passed or any non-zero value to it if the test is failed.
