# Architecture selection
#
# CONFIG_ARCH - identifies the arch subdirectory and, hence, the
#   processor architecture.
# CONFIG_ARCH_architecture - for use in C code.  This identifies the
#   specific architecture within the chip familyl.
# 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)
# 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_IRQPRIO - Set if the architecture 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

# General OS setup
#
# CONFIG_APPS_DIR - Identifies the relative path to the directory that builds
#   the application to link with NuttX.  Default: ../apps
# CONFIG_DEBUG - enables built-in debug options
# CONFIG_DEBUG_VERBOSE - enables verbose debug output
# CONFIG_DEBUG_SYMBOLS - build without optimization and with debug symbols
#  (needed for use with a debugger).
# 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_ARCH_LOWPUTC - architecture supports low-level, boot time console
#   output.
# CONFIG_MSEC_PER_TICK - The default system timer is 100Hz or MSEC_PER_TICK=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.
# CONFIG_DEV_LOWCONSOLE - Use the simple, low-level serial console driver
#   (minimal support)

#   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.
