# 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
#
# $Id$

# 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
#
# STACK_CHECKER_ON (RTEMS support code)
# If defined, stack bounds checking is enabled.
#
# STACK_CHECKER_REPORT_USAGE (RTEMS support code)
# If this and STACK_CHECKER_ON are defined, then a report on stack usage
# per task is printed when the program exits.
#
# 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_ABI (ppc)
# This defines the calling convention (Application Binary Interface)
# used in this configuration. EABI is the only one supported.
#
# PPC_ASM (ppc)
# This defines the assembly language format used in this configuration.
# ELF is the only one supported.
