# CONFIG_ARCH - identifies the arch subdirectory and, hence, the
# processor architecture.
# CONFIG_ARCH_name - for use in C code. This identifies the

# in.
# CONFIG_ARCH_BOARD - identifies the configs subdirectory and, hence,
# the board that supports the particular chip or SoC.
# CONFIG_ARCH_BOARD_name - for use in C code
# CONFIG_ENDIAN_BIG - define if big endian (default is little endian)

# CONFIG_EXAMPLE - identifies the subdirectory in examples

# CONFIG_DEBUG - enables built-in debug options
# CONFIG_DEBUG_VERBOSE - enables verbose debug output
# CONFIG_MM_REGIONS - If the architecture includes multiple
# regions of memory to allocate from, this specifies the
# number of memory regions that the memory manager must
# handle and enables the API mm_addregion(start, end);
# CONFIG_HAVE_LOWPUTC - architecture supports low-level, boot
# time console output
# CONFIG_TICKS_PER_MSEC - The default system timer is 100Hz
# or TICKS_PER_MSEC=10. This setting may be defined to
# inform NuttX that the processor hardware is providing
# system timer interrupts at some interrupt interval other
# than 10 msec.
# CONFIG_RR_INTERVAL - The round robin timeslice will be set
# this number of milliseconds; Round robin scheduling can
# be disabled by setting this value to zero.
# CONFIG_SCHED_INSTRUMENTATION - enables instrumentation in
# scheduler to monitor system performance
# CONFIG_TASK_NAME_SIZE - Spcifies that maximum size of a
# task name to save in the TCB. Useful if scheduler
# instrumentation is selected. Set to zero to disable.
# CONFIG_JULIAN_TIME - Enables Julian time conversions
# CONFIG_START_YEAR, CONFIG_START_MONTH, CONFIG_START_DAY -
# Used to initialize the internal time logic.
# CONFIG_DEV_CONSOLE - Set if architecture-specific logic
# provides /dev/console. Enables stdout, stderr, stdin.
