+# architecture selection
+#
+# CONFIG_ARCH - identifies the arch subdirectory and, hence, the
+#   processor architecture.
+# CONFIG_ARCH_family - for use in C code.  This identifies the
+#   particular chip family that the architecture is implemented
+#   in.
+# CONFIG_ARCH_architecture - for use in C code.  This identifies the
+#   specific architecture within the chip family.
+# CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+# CONFIG_ARCH_CHIP_name - For use in C code
+# 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)
+#   NOTE: The PIC32MX is always little endian.
+# CONFIG_BOARD_LOOPSPERMSEC - for delay loops
+# CONFIG_DRAM_SIZE - Describes the installed DRAM.
+# CONFIG_DRAM_START - The start address of DRAM (physical)
+# CONFIG_DRAM_END - Last address+1 of installed RAM
+# CONFIG_ARCH_NOINTC - define if the architecture does not
+#   support an interrupt controller or otherwise cannot support
+#   APIs like up_enable_irq() and up_disable_irq().
+# CONFIG_ARCH_VECNOTIRQ - Usually the interrupt vector number provided
+#   to interfaces like irq_attach() and irq_detach are the same as IRQ
+#   numbers that are provied to IRQ management functions like
+#   up_enable_irq() and up_disable_irq().  But that is not true for all
+#   interrupt controller implementations.  For example, the PIC32MX
+#   interrupt controller manages interrupt sources that have a many-to-one
+#   relationship to interrupt vectors. In such cases, CONFIG_ARCH_VECNOTIRQ
+#   must defined so that the OS logic will know not to assume it can use
+#   a vector number to enable or disable interrupts.
+# CONFIG_ARCH_IRQPRIO - The PIC32MX supports interrupt prioritization
+# CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+#   stack. If defined, this symbol is the size of the interrupt
+#   stack in bytes.  If not defined, the user task stacks will be
+#   used during interrupt handling.
+# CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+# CONFIG_ARCH_BOOTLOADER - Set if you are using a bootloader.
+# CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+# CONFIG_ARCH_BUTTONS -  Enable support for buttons. Unique to board architecture.
+# CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+#   cause a 100 second delay during boot-up.  This 100 second delay
+#   serves no purpose other than it allows you to calibrate
+# CONFIG_BOARD_LOOPSPERMSEC.  You simply use a stop watch to measure
+#   the 100 second delay then adjust CONFIG_BOARD_LOOPSPERMSEC until
+#   the delay actually is 100 seconds.
+# CONFIG_ARCH_DMA - Support DMA initialization

+# 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_FAT_MAXFNAME - If CONFIG_FAT_LFN is defined, then the
