37
#  NDEBUG (C library)
38
#     if defined asserts do not generate code.  This is commonly used
39
#     as a command line option.
40
#
41
#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
42
#     do not pause between screens of output in the rtems tests
43
#
44
#  RTEMS_DEBUG (RTEMS)
45
#     If defined, debug checks in RTEMS and support library code are enabled.
46
#
47
#  CONSOLE_USE_POLLED     (score603e_bsp)
48
#  CONSOLE_USE_INTERRUPTS (score603e_bsp)
49
#     The score603e console driver has the structure to operate in either
50
#     polled or interrupt mode.  However both modes only trap to the
51
#     monitor currently.
52
#
53
#  SCORE603E_USE_SDS           (score603e_bsp)
54
#  SCORE603E_USE_OPEN_FIRMWARE (score603e_bsp)
55
#  SCORE603E_USE_NONE          (score603e_bsp)
56
#     The Score603e board can be configured with 3 ROM monitors.  Only two
57
#     are appropriate for use with RTEMS.  Set exactly one of these to "1"
58
#     to indicate which ROM monitor is on the board you are using.
59
#
60
#  PPC_VECTOR_FILE_BASE (ppc)
61
#     This defines the base address of the exception table.
62
#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
63
#
64
#  PPC_USE_SPRG (RTEMS PowerPC port)
65
#     If defined, then the PowerPC specific code in RTEMS will use some
66
#     of the special purpose registers to slightly optimize interrupt
67
#     response time.  The use of these registers can conflict with
68
#     other tools like debuggers.
69
#
70
#  PPC_USE_DATA_CACHE (RTEMS PowerPC port)
71
#     If defined, then the PowerPC specific code in RTEMS will use
72
#     data cache instructions to optimize the context switch code.
73
#     This code can conflict with debuggers or emulators.
