39Notes
40=====
41The device tree for this BSP is included with rtems-tools and automated
42testing of psim is supported by the RTEMS Tester. See
43rtems-tools/tester/rtems/testing/bsps/psim-device-tree for specifics. This
44file must be kept in sync with startup/linkcmds and the MMU initialization
45in the BSP.
46
47For the multiprocessing tests to run, psim supports an area of UNIX
48shared memory and UNIX semaphore mapped into the PowerPC address space.
