#  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: dmv177.cfg,v 1.14.2.3 2000/05/28 17:52:30 joel Exp $

include $(RTEMS_ROOT)/make/custom/default.cfg

RTEMS_CPU=powerpc
RTEMS_CPU_MODEL=ppc603e

# This is the actual bsp directory used during the build process.
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.
