# This target does NOT support the TCP/IP stack so ignore requests
# to enable it.
HAS_NETWORKING=no
# 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.
#
#
# PPC_VECTOR_FILE_BASE (PowerPC)
# This defines the base address of the exception table.
# NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
#
# PPC_ABI (PowerPC)
# This defines the calling convention (Application Binary Interface)
# used in this configuration. EABI is the only one supported.
# This BSP was initially developed using the PowerOpen ABI.
#
# PPC_ASM (PowerPC)
# This defines the assembly language format used in this configuration.
# ELF is the only one supported.
#
# 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.
