#
# Config file for a PowerPC 603e based DY-4 VMEbus Single Board Computer.
# This BSP should work with the following models:
#
# + SVME-171/DMV-171
# + SVME-176/DMV-176

RTEMS_BSP_FAMILY=dmv177
# 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.
#
# PPC_VECTOR_FILE_BASE (ppc)
# 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.
#
# PPC_USE_DATA_CACHE (RTEMS PowerPC port/BSP)
# 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. It is known
# to break the Corelis PowerPC emulator with at least some combinations
# of PowerPC 603e revisions and emulator versions.
# The BSP actually contains the call that enables this.
#
# PPC_USE_INSTRUCTION_CACHE (RTEMS PowerPC port/BSP)
# 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.
# The BSP actually contains the call that enables this.
