# 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

#   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
