SAMDL: Added SAMD DAC header file. Fixed SAMD EVSYS header. Added SAMD TC header file. Fixed some minor typos

* SAMD External Interrupt Controller (EIC) support

* removed comment

* SAMDL: SPI must be disabled before changing the mode bits in CTRLA register

* arch/arm/src/lc823450: Assign I2S IRQ handling to CPU0

    Previous commit assumed that the caller is running on CPU0.
    However, the caller sometimes runs at CPU1.  This patch will
    assign the caller to CPU0 explicitly.

* configst/stm3240g-eval:  Remove only bogus logic to start the NX server.  That was there only to support the knxwm configuration and was implemented priorit to boardctl(BOARCIOC_NX_START).

* drivers/input/ft5x06.c:  Remove cool logic to disable polling when there there is no client waiting for read data.  That was a great idea to save CPU cycles when there is nothing reading from the touchscrren but, unfortunately, does not work with readers that open the driver in non-blocking mode.  So I think we just have to eat the CPUs even when there is nothing waiting for touchscreen input.

* The existence of the network driver ioctl() method should depend on CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL.  The former enables the method, the later enables a subset of possible driver IOCTLs.  This change should be basically a no-operation.  The affected ioctl methods only support those subset of driver IOCTLs selected by CONFIG_NETDEV_PHY_IOCTL and the network logic will tolerate a nul ioctl method.

* net/tcp:  Write buffering logic should not wait for a free buffer if the socket was opened non-blocking.  Also, rename the TCP write buffering macros from WRB_* to TCPWB_* to make room in the namespace for write buffering with other protocols.

* net/udp:  Remove some conditional logic that was true if there is only a single network device, but not true in the multi-device context.

* This commit adds an as-of-yet untested implemented of UDP write buffering.

    Squashed commit of the following:

        net/udp:  Address most of the issues with UDP write buffering.  There is a remaining issue with handling one network going down in a multi-network environment.  None of this has been test but it is certainly ready for test.  Hence, the feature is marked EXPERIMENTAL.
        net/udp:  Some baby steps toward a corrected write buffering design.
        net/udp:  Remove pesky write buffer macros.
        Eliminate trailing space at the end of lines.
        net/udp:  A little more UDP write buffering logic.  Still at least on big gaping hole in the design.
        net/udp:  Undefined CONFIG_NET_SENDTO_TIMEOUT.
        net/udp:  Crude, naive port of the TCP write buffering logic into UDP.  This commit is certainly non-functional and is simply a starting point for the implementatin of UDP write buffering.
        net/udp:  Rename udp/udp_psock_sendto.c udp/udp_psock_sendto_unbuffered.c.

* net/udp:  In sendto(), return EHOSTUNREACH if if the network is down.

* net/udp:  Resolves final design issues with UDP write buffering.  100% code complete but also 100% untested.

* net/udp and tcp:  Yet another (cosmetic) change to UDP and TCP write buffer macro naming.

* net/udp:  UDP write buffering is basically functional but needs a lot more verification.

* net/udp:  Fix memory leak with UDP + write buffer is closed.  Also update TODO and comments and refresh a configuration.

* Update some comments.

* drivers/mtd/at24xx.c: Correct page size for AT24C02 part.

* arch/arm/src/stm32:  Make STM32 usable with an external RTC.   drivers/timers/ds3231.c:  Correct some debug statments.

* arch/arm/src/stm32/stm32_spi.c: Removed unnecessary (and incorrect) speed limitation

* arch/arm/src/stm32/stm32f40xxx_i2c.c:  Correct some recent changes to STM32F4 I2C that broke poll mode of operation.

* configs/flipnclick-sam3x:  Using JTAG (vs. Bossac) I was finally able to load code and verify the basic NSH configuration.  Updated READMEs.  Also switched to USART0 (vs UART0) for the serial console because I was not getting bi-directional communication on the VCOM.

* SAMDL: Added SAMD DAC header file. Fixed SAMD EVSYS header. Added SAMD TC header file. Fixed some minor typos

* fix typo

* added missing EVCTRL register bits in TC

Table of Contents

  o Configuring NuttX

Architecture-Specific Code
^^^^^^^^^^^^^^^^^^^^^^^^^^

The NuttX configuration consists of:

o Processor architecture specific files.  These are the files contained
  in the arch/<arch-name>/ directory discussed in this README.

o Chip/SoC specific files.  Each processor processor architecture
  is embedded in chip or System-on-a-Chip (SoC) architecture.  The
  full chip architecture includes the processor architecture plus
  chip-specific interrupt logic, general purpose I/O (GIO) logic, and
  specialized, internal peripherals (such as UARTs, USB, etc.).

  These chip-specific files are contained within chip-specific
  sub-directories in the arch/<arch-name>/ directory and are selected
  via the CONFIG_ARCH_name selection

o Board specific files.  In order to be usable, the chip must be
  contained in a board environment.  The board configuration defines
  additional properties of the board including such things as
  peripheral LEDs, external peripherals (such as network, USB, etc.).

  These board-specific configuration files can be found in the
  configs/<board-name>/ sub-directories.

This README will address the processor architecture specific files
that are contained in the arch/<arch-name>/ directory. The file
include/nuttx/arch.h identifies all of the APIs that must
be provided by this architecture specific logic.  (It also includes
arch/<arch-name>/arch.h as described below).

Directory Structure
^^^^^^^^^^^^^^^^^^^

The arch directory contains architecture specific logic.  The complete
board port in is defined by the architecture-specific code in this
directory (plus the board-specific configurations in the config/
subdirectory).  Each architecture must provide a subdirectory <arch-name>
under arch/ with the following characteristics:


        <arch-name>/
        |-- include/
        |   |--<chip-name>/
        |   |  `-- (chip-specific header files)
        |   |--<other-chips>/
        |   |-- arch.h
        |   |-- irq.h
        |   `-- types.h
        `-- src/
            |--<chip-name>/
            |  `-- (chip-specific source files)
            |--<other-chips>/
            |-- Makefile
            `-- (architecture-specific source files)

Summary of Files
^^^^^^^^^^^^^^^^

include/<chip-name>/
  This sub-directory contains chip-specific header files.

include/arch.h
  This is a hook for any architecture specific definitions that may
  be needed by the system.  It is included by include/nuttx/arch.h

include/types.h
  This provides architecture/toolchain-specific definitions for
  standard types.  This file should typedef:

    _int8_t, _uint8_t, _int16_t, _uint16_t, _int32_t, _uint32_t

  and if the architecture supports 64-bit integers.

    _int24_t, _uint24_t, int64_t, uint64_t

  NOTE that these type names have a leading underscore character.  This
  file will be included(indirectly) by include/stdint.h and typedef'ed to
  the final name without the underscore character.  This roundabout way of
  doings things allows the stdint.h to be removed from the include/
  directory in the event that the user prefers to use the definitions
  provided by their toolchain header files

    irqstate_t

  Must be defined to the be the size required to hold the interrupt
  enable/disable state.

  This file will be included by include/sys/types.h and be made
  available to all files.

include/irq.h
  This file needs to define some architecture specific functions (usually
  inline if the compiler supports inlining) and structure.  These include:

  - struct xcptcontext.  This structures represents the saved context
    of a thread.

  - irqstate_t up_irq_save(void) -- Used to disable all interrupts.

  - void upirq_restore(irqstate_t flags) -- Used to restore interrupt
    enables to the same state as before up_irq_save was called.

  NOTE: These interfaces are not available to application code but can
  only be used withint the operating system code.  And, in general,
  these functions should *never* be called directly, not unless you
  know absolutely well what you are doing.  Rather you shoudl typically
  use the wrapper functions enter_critical_section() and leave_critical_section()
  as prototyped in include/nuttx/irq.h.

  This file must also define NR_IRQS, the total number of IRQs supported
  by the board.

src/<chip-name>/
  This sub-directory contains chip-specific source files.

src/Makefile
  This makefile will be executed to build the targets src/libup.a and
  src/up_head.o.  The up_head.o file holds the entry point into the system
  (power-on reset entry point, for example).  It will be used in
  the final link with libup.a and other system archives to generate the
  final executable.

Supported Architectures
^^^^^^^^^^^^^^^^^^^^^^^
NOTE: nuttx/Documentation/NuttX.html for current information about the
state of these MCU ports.

arch/sim - Linux/Cygwin simulation
    A user-mode port of NuttX to the x86 Linux platform is available.
    The purpose of this port is primarily to support OS feature development.
    This port does not support interrupts or a real timer (and hence no
    round robin scheduler)  Otherwise, it is complete.
