-# architecture selection

-# CONFIG_ARCH - identifies the arch subdirectory and, hence, the

-# CONFIG_BOARD_LOOPSPERMSEC - for delay loops

-# CONFIG_DEBUG_VERBOSE - enables verbose debug output
-# CONFIG_DEBUG_SYMBOLS - build without optimization and with
-#   debug symbols (needed for use with a debugger).
-# CONFIG_HAVE_CXX - Enable support for C++
-# CONFIG_HAVE_CXXINITIALIZE - The platform-specific logic includes support
-#   for initialization of static C++ instances for this architecture
-#   and for the selected toolchain (via up_cxxinitialize()).
-# CONFIG_MM_REGIONS - If the architecture includes multiple
-#   regions of memory to allocate from, this specifies the

-# CONFIG_ARCH_LOWPUTC - architecture supports low-level, boot
-#   time console output
-# CONFIG_MSEC_PER_TICK - The default system timer is 100Hz

-#   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

-# 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

-# 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.
-# CONFIG_DEV_LOWCONSOLE - Use the simple, low-level serial console
-#   driver (minimul support)
-# CONFIG_MUTEX_TYPES: Set to enable support for recursive and
-#   errorcheck mutexes. Enables pthread_mutexattr_settype().
-# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
-#   inheritance on mutexes and semaphores. 
-# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
-#   inheritance is enabled.  It defines the maximum number of
-#   different threads (minus one) that can take counts on a
-#   semaphore with priority inheritance support.  This may be 
-#   set to zero if priority inheritance is disabled OR if you
-#   are only using semaphores as mutexes (only one holder) OR
-#   if no more than two threads participate using a counting
-#   semaphore.
-# CONFIG_SEM_NNESTPRIO.  If priority inheritance is enabled,
-#   then this setting is the maximum number of higher priority
-#   threads (minus 1) than can be waiting for another thread
-#   to release a count on a semaphore.  This value may be set
-#   to zero if no more than one thread is expected to wait for
-#   a semaphore.
-# CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors
-#   by task_create() when a new task is started.  If set, all
-#   files/drivers will appear to be closed in the new task.
-# CONFIG_FDCLONE_STDIO. Disable cloning of all but the first
-#   three file descriptors (stdin, stdout, stderr) by task_create()
-#   when a new task is started. If set, all files/drivers will
-#   appear to be closed in the new task except for stdin, stdout,
-#   and stderr.
-# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
-#   desciptors by task_create() when a new task is started. If
-#   set, all sockets will appear to be closed in the new task.
-# CONFIG_SCHED_WORKQUEUE.  Create a dedicated "worker" thread to
-#  handle delayed processing from interrupt handlers.  This feature
-#  is required for some drivers but, if there are not complaints,
-#  can be safely disabled.  The worker thread also performs
-#  garbage collection -- completing any delayed memory deallocations
-#  from interrupt handlers.  If the worker thread is disabled,
-#  then that clean will be performed by the IDLE thread instead
-#  (which runs at the lowest of priority and may not be appropriate
-#  if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE
-#  is enabled, then the following options can also be used:
-# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
-#  thread.  Default: 50
-# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
-#  work in units of microseconds.  Default: 50*1000 (50 MS).
-# CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker
-#  thread.  Default: CONFIG_IDLETHREAD_STACKSIZE.
-# CONFIG_SIG_SIGWORK - The signal number that will be used to wake-up
-#  the worker thread.  Default: 4
-# CONFIG_SCHED_WAITPID - Enable the waitpid() API
-# CONFIG_SCHED_ATEXIT - Enabled the atexit() API
