include $(RTEMS_ROOT)/make/custom/default.cfg
# 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 (score603e_bsp)
# CONSOLE_USE_INTERRUPTS (score603e_bsp)
# The score603e console driver has the structure to operate in either
# polled or interrupt mode. However both modes only trap to the
# monitor currently.
#
# SCORE603E_USE_SDS (score603e_bsp)
# SCORE603E_USE_OPEN_FIRMWARE (score603e_bsp)
# SCORE603E_USE_NONE (score603e_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_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.
#
# 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.
