RTEMS_CPU_MODEL=ppc603e

# This is the actual bsp directory used during the build process.

RTEMS_BSP_FAMILY=psim

#  This section makes the target dependent options file.

#  NDEBUG (C library)

#     if defined asserts do not generate code.  This is commonly used

#     as a command line option.

#

#  RTEMS_TEST_NO_PAUSE (RTEMS tests)

#     do not pause between screens of output in the rtems tests

#

#  RTEMS_DEBUG (RTEMS)

#     If defined, debug checks in RTEMS and support library code are enabled.

#

#  CONSOLE_USE_POLLED     (psim_bsp)

#  CONSOLE_USE_INTERRUPTS (psim_bsp)

#     The psim console driver has the structure to operate in either

#     polled or interrupt mode.  However both modes only trap to the

#     monitor currently.

#

#  PSIM_FAST_IDLE (psim_bsp)

#     If defined, speed up the clock ticks while the idle task is running so

#     time spent in the idle task is minimized.  This significantly reduces

#     the wall time required to execute the RTEMS test suites.

#

#  PPC_VECTOR_FILE_BASE (PowerPC)

#     This defines the base address of the exception table.

#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100

#

#  PPC_USE_SPRG (RTEMS PowerPC port)

#     If defined, then the PowerPC specific code in RTEMS will use some

#     of the special purpose registers to slightly optimize interrupt

#     response time.  The use of these registers can conflict with

#     other tools like debuggers.
