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

# This contains the compiler options necessary to select the CPU model
# This section makes the target dependent options file.
# 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.
