18# The value assigned to RTEMS_CPU, RTEMS_CPU_MODEL and RTEMS_BSP get

23# For the MBX860 and MBX821, the boards and processors are sufficiently
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#  NVRAM_CONFIGURE
68#    Define to 1 if you want the console driver, network driver and caches
69#    configured at boot time from parameters stored in NVRAM. If set to 1,
70#    most parameters below are ignored during the build. If not set to 1,
71#    then the console driver is configured at build time, the network host
72#    information is obtained from application supplied data structures, and
73#    the caches are configured at boot time based on the information supplied
74#    in this file.
75#
76#  UARTS_USE_TERMIOS
77#    Define to 1 if you want termios support for every port.
78#    Termios support is independent of the choice of UART I/O mode.
79#
80#  CONSOLE_MINOR (BSP--console driver)
81#    Must be defined to be one of SMC1_MINOR, SMC2_MINOR, SCC2_MINOR,
82#    SCC3_MINOR, or SCC4_MINOR. Determines which device will be registered
83#    as /dev/console.
84#
85#  UARTS_IO_MODE (BSP--console driver)
86#    Define to 0 or 1 if you want polled I/O performed by RTEMS.
87#    Define to 1 if you want interrupt-driven performed by RTEMS.
88#    Define to 2 if you want polled I/O performed by EPPCBug.
89#    There is no provision to have a mix of interrupt-driven and polled I/O
90#    ports, except that the printk port may use a different mode from the
91#    other ports. If this is done, do not open the printk port from an RTEMS
92#    application. With EPPCBug 1.1, if mode 2 is selected, CONSOLE_MINOR must
93#    be set to SMC1_MINOR. This is a deficiency of the firmware: it does not
94#    perform serial I/O on any port other than its default debug port, which
95#    must be SMC1.
96#
97#  PRINTK_MINOR (BSP--console driver)
98#    Must be defined to be one of SMC1_MINOR, SMC2_MINOR, SCC2_MINOR,
99#    SCC3_MINOR, or SCC4_MINOR. Determines which device is used for output
100#    by printk(). If the port that printk() uses is also used for other I/O
101#    (e.g. if  PRINTK_MINOR == CONSOLE_MINOR), then both ports should use
102#    the same type of I/O, otherwise the drivers will likely conflict with
103#    each other.
104#
105#  PRINTK_IO_MODE (BSP--console driver)
106#    Define to 0 or 1 if you want polled I/O performed by RTEMS.
107#    Define to 2 if you want polled I/O performed by EPPCBug.
108#    The printk() port is not configured to use termios. With EPPCBug 1.1,
109#    if mode 2 is selected, PRINTK_MINOR must be set to SMC1_MINOR.
110#    This is a deficiency of the firmware: it does not perform serial I/O
111#    on any port other than its default debug port, which must be SMC1.
112#    Printk always uses polled output.
113#
114#  EPPCBUG_SMC1 (BSP--console driver)
115#    If defined, SMC1 is in use by EPPC-Bug. The console driver will not
116#    re-initialize that port.
117#
118#  INSTRUCTION_CACHE_ENABLE (BSP--RTEMS)
119#    If defined, the instruction cache will be enabled after address translation
120#    is turned on.
121#
122#  DATA_CACHE_ENABLE (BSP--RTEMS)
123#    If defined, the data cache will be enabled after address translation
124#    is turned on.
125#   
126#  EPPCBUG_VECTORS (BSP--RTEMS)
127#    If defined, vectors branch to EPPCBug, except the following:
128#    0x500 (external interrupt), 0x900 (decrementer).
129#
130#  PowerPC-specific options:
131#       
132#  PPC_USE_DATA_CACHE (RTEMS PowerPC port)
133#     If defined, then the PowerPC specific code in RTEMS will use
134#     data cache instructions to optimize the context switch code.
135#     This code can conflict with debuggers or emulators.
