#
#  Config file for a Radstone Technology Plc. PowerPC 60x based VME board
#
#  $Id: ppcn_60x.cfg
#

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=ppcn_60x

#  This contains the compiler options necessary to select the CPU model
#  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.
#
#  PPCN_60X_USE_DINK           (ppcn_60x_bsp)
#  PPCN_60X_USE_NONE          (ppcn_60x_bsp)
#     The Score603e board can be configured with 3 ROM monitors.  Only two
#     are appropriate for use with RTEMS.  Set exactly one of these to "1"
#     to indicate which ROM monitor is on the board you are using.
#
#  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)
#     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.
