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

+# 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 Cortex-M4 supports interrupt prioritization
+# CONFIG_ARCH_FPU - The Cortex-M4 supports a floating point unit (FPU)
+#   (But, unfortunately, most versions of GCC do not support it).
+# 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_ARMV7M_CMNVECTOR - This must be defined to indicate that the
