# 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 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_IRQPRIO - The LM3S6965 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_LEDS -  Use LEDs to show state. Unique to board architecture.
# CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that

#   serves no purpose other than it allows you to calibratre
#   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.

# Stack and heap information
#
# CONFIG_BOOT_RUNFROMFLASH - Some configurations support XIP
#   operation from FLASH but must copy initialized .data sections to RAM.
#   (should also be =n for the LM3S6965 Eval Kit which always runs from flash)
# CONFIG_BOOT_COPYTORAM -  Some configurations boot in FLASH
#   but copy themselves entirely into RAM for better performance.
# CONFIG_CUSTOM_STACK - The up_ implementation will handle
#   all stack operations outside of the nuttx model.
# CONFIG_STACK_POINTER - The initial stack pointer (arm7tdmi only)
# CONFIG_IDLETHREAD_STACKSIZE - The size of the initial stack.
#  This is the thread that (1) performs the inital boot of the system up
#  to the point where user_start() is spawned, and (2) there after is the
#  IDLE thread that executes only when there is no other thread ready to
#  run.
# CONFIG_USERMAIN_STACKSIZE - The size of the stack to allocate
#  for the main user thread that begins at the user_start() entry point.
# CONFIG_PTHREAD_STACK_MIN - Minimum pthread stack size
# CONFIG_PTHREAD_STACK_DEFAULT - Default pthread stack size
# CONFIG_HEAP_BASE - The beginning of the heap
# CONFIG_HEAP_SIZE - The size of the heap
