|
|
#
|
|
# MBX8xx-specific options:
|
|
#
|
|
# NVRAM_CONFIGURE
|
|
# Define to 1 if you want the console driver, network driver and caches
|
|
# configured at boot time from parameters stored in NVRAM. If set to 1,
|
|
# most parameters below are ignored during the build. If not set to 1,
|
|
# then the console driver is configured at build time, the network host
|
|
# information is obtained from application supplied data structures, and
|
|
# the caches are configured at boot time based on the information supplied
|
|
# in this file.
|
|
#
|
|
# UARTS_USE_TERMIOS
|
|
# Define to 1 if you want termios support for every port.
|
|
# Termios support is independent of the choice of UART I/O mode.
|
|
#
|
|
# CONSOLE_MINOR (BSP--console driver)
|
|
# Must be defined to be one of SMC1_MINOR, SMC2_MINOR, SCC2_MINOR,
|
|
# SCC3_MINOR, or SCC4_MINOR. Determines which device will be registered
|
|
# as /dev/console.
|
|
#
|
|
# UARTS_IO_MODE (BSP--console driver)
|
|
# Define to 0 or 1 if you want polled I/O performed by RTEMS.
|
|
# Define to 1 if you want interrupt-driven performed by RTEMS.
|
|
# Define to 2 if you want polled I/O performed by EPPCBug.
|
|
# There is no provision to have a mix of interrupt-driven and polled I/O
|
|
# ports, except that the printk port may use a different mode from the
|
|
# other ports. If this is done, do not open the printk port from an RTEMS
|
|
# application. With EPPCBug 1.1, if mode 2 is selected, CONSOLE_MINOR must
|
|
# be set to SMC1_MINOR. This is a deficiency of the firmware: it does not
|
|
# perform serial I/O on any port other than its default debug port, which
|
|
# must be SMC1.
|
|
#
|
|
# PRINTK_MINOR (BSP--console driver)
|
|
# Must be defined to be one of SMC1_MINOR, SMC2_MINOR, SCC2_MINOR,
|
|
# SCC3_MINOR, or SCC4_MINOR. Determines which device is used for output
|
|
# by printk(). If the port that printk() uses is also used for other I/O
|
|
# (e.g. if PRINTK_MINOR == CONSOLE_MINOR), then both ports should use
|
|
# the same type of I/O, otherwise the drivers will likely conflict with
|
|
# each other.
|
|
#
|
|
# PRINTK_IO_MODE (BSP--console driver)
|
|
# Define to 0 or 1 if you want polled I/O performed by RTEMS.
|
|
# Define to 2 if you want polled I/O performed by EPPCBug.
|
|
# The printk() port is not configured to use termios. With EPPCBug 1.1,
|
|
# if mode 2 is selected, PRINTK_MINOR must be set to SMC1_MINOR.
|
|
# This is a deficiency of the firmware: it does not perform serial I/O
|
|
# on any port other than its default debug port, which must be SMC1.
|
|
# Printk always uses polled output.
|
|
#
|
|
# EPPCBUG_SMC1 (BSP--console driver)
|
|
# If defined, SMC1 is in use by EPPC-Bug. The console driver will not
|
|
# re-initialize that port.
|
|
#
|
|
# INSTRUCTION_CACHE_ENABLE (BSP--RTEMS)
|
|
# If defined, the instruction cache will be enabled after address translation
|
|
# is turned on.
|
|
#
|
|
# DATA_CACHE_ENABLE (BSP--RTEMS)
|
|
# If defined, the data cache will be enabled after address translation
|
|
# is turned on.
|
|
#
|
|
# EPPCBUG_VECTORS (BSP--RTEMS)
|
|
# If defined, vectors branch to EPPCBug, except the following:
|
|
# 0x500 (external interrupt), 0x900 (decrementer).
|
|
#
|
|
# PowerPC-specific options:
|
|
#
|
|
# PPC_USE_SPRG (RTEMS PowerPC port)
|
|
# If defined (=1), 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. This should be 0 when using EPPCBug
|
|
# because its uses most SPRGs (do not believe the documentation!).
|
|
#
|
|
# PPC_USE_DATA_CACHE (RTEMS PowerPC port)
|
|
# If defined, then the PowerPC specific code in RTEMS will use
|
|
# data cache instructions to optimize the context switch code.
|
|
# This code can conflict with debuggers or emulators.
