24# similar that the ports are unified and use RTEMS_CPU_MODEL=mpc8xx and

61#  The specific CPU model is defined, so the few places that require
62#  different code for the MPC860 and MPC821 can be distinguished.
63#  Either mpc860 or mpc821 is defined.
64#
65#  MBX8xx-specific options:
66#
67#  UARTS_USE_TERMIOS
68#    Define to 1 if you want termios support for every port.
69#    Termios support is independent of the choice of UART I/O mode.
70#
71#  CONSOLE_MINOR (BSP--console driver)
72#    Must be defined to be one of SMC1_MINOR, SMC2_MINOR, SCC2_MINOR,
73#    SCC3_MINOR, or SCC4_MINOR. Determines which device will be registered
74#    as /dev/console.
75#
76#  UARTS_IO_MODE (BSP--console driver)
77#    Define to 0 if you want polled I/O performed by RTEMS.
78#    Define to 1 if you want interrupt-driven performed by RTEMS.
79#    Define to 2 if you want polled I/O performed by EPPCBug.
80#    There is no provision to have a mix of interrupt-driven and polled I/O
81#    ports, except that the printk port may use a different mode from the
82#    other ports. If this is done, do not open the printk port from an RTEMS
83#    application. With EPPCBug 1.1, if mode 2 is selected, CONSOLE_MINOR must
84#    be set to SMC1_MINOR. This is a deficiency of the firmware: it does not
85#    perform serial I/O on any port other than its default debug port, which
86#    must be SMC1.
87#
88#  PRINTK_MINOR (BSP--console driver)
89#    Must be defined to be one of SMC1_MINOR, SMC2_MINOR, SCC2_MINOR,
90#    SCC3_MINOR, or SCC4_MINOR. Determines which device is used for output
91#    by printk(). If the port that printk() uses is also used for other I/O
92#    (e.g. if  PRINTK_MINOR == CONSOLE_MINOR), then both ports should use
93#    the same type of I/O, otherwise the drivers will likely conflict with
94#    each other.
95#
96#  PRINTK_IO_MODE (BSP--console driver)
97#    Define to 0 if you want polled I/O performed by RTEMS.
98#    Define to 1 if you want interrupt-driven I/O performed by RTEMS.
99#    Define to 2 if you want polled I/O performed by EPPCBug.
100#    The printk() port is not configured to termios. The only way to
101#    use printk() with interrupt-driven I/O, which always uses termios,
102#    is to open the printk port from an RTEMS application. One way to
103#    do this is to have PRINTK_MINOR == CONSOLE_MINOR. With EPPCBug 1.1,
104#    if mode 2 is selected, PRINTK_MINOR must be set to SMC1_MINOR.
105#    This is a deficiency of the firmware: it does not perform serial I/O
106#    on any port other than its default debug port, which must be SMC1.
107#
108#  EPPCBUG_SMC1 (BSP--console driver)
109#    If defined, SMC1 is in use by EPPC-Bug. The console driver will not
110#    re-initialize that port.
111#
112#  EPPCBUG_VECTORS (BSP--RTEMS)
113#    If defined, vectors branch to EPPCBug, except the following:
114#    0x500 (external interrupt), 0x900 (decrementer).
115#
116#  INSTRUCTION_CACHE_ENABLE (BSP--RTEMS)
117#    If defined, the instruction cache will be enabled after address translation
118#    is turned on.
119#
120#  DATA_CACHE_ENABLE (BSP--RTEMS)
121#    If defined, the data cache will be enabled after address translation
122#    is turned on.
123#   
124#  PowerPC-specific options:
125#       
126#  PPC_USE_SPRG (RTEMS PowerPC port)
127#     If defined (=1), then the PowerPC specific code in RTEMS will use some
128#     of the special purpose registers to slightly optimize interrupt
129#     response time.  The use of these registers can conflict with
130#     other tools like debuggers.  This should be 0 when using EPPCBug
131#     because its uses most SPRGs (don't believe the documentation!).
132#
133#  PPC_USE_DATA_CACHE (RTEMS PowerPC port)
134#     If defined, then the PowerPC specific code in RTEMS will use
135#     data cache instructions to optimize the context switch code.
136#     This code can conflict with debuggers or emulators.
