[bsp][synopsys] add basic new embarc bsp support

* the initial support of synopsys designware ARC processor
  using embARC_BSP, all synopsys ARC-based boards are
  supported:
  -ARC Software Development Platform
  -ARC EM Starter Kit
  -ARC EM Software Development Platform
  -ARC HS Development Kit
  -ARC IoT Development Kit

* The embARC BSP is a new generation embARC software development
  package.  ​It is designed to be the inter-layer between hardware and
  operating system. ​ BSP could hide the difference of hardware/boards,
  provide a unified interface to upper-layer.

* the initial support of synopsys MWDT toolchain.
  The DesignWare® ARC® MetaWare Development Toolkit builds upon
  a 25-year legacy of industry-leading compiler and debugger products.
  It is a complete solution that contains all the components needed to
  support the development, debugging and tuning of embedded applications
  for the DesignWare ARC processors.

* for detailed board information, pls go embarc.org.

+# Synopsys ARC Boards support with embARC_BSP
+
+## embARC_BSP
+
+The embARC Board support Package (BSP) is a software distributions aimed at facilitating
+the development and evaluation of embedded systems based on ARCv2 processors, which is
+designed to provide a minimal board support package for ARC users by defining
+consistent and simple software interfaces to the processors and onboard devices.
+
+The embARC BSP is a new generation embARC software development package. ​
+It is designed to be the inter-layer between hardware and operating system. ​
+BSP could hide the difference of hardware/boards, provide a unified interface to upper-layer. ​
+In the scenarios that no OS is required, embARC BSP can also standalone and work in baremetal.
+
+embARC_BSP features:
+
+* Support MetaWare & GNU toolchains​
+* Support all development boards and tcf​
+* Support various build systems and compiling environments,
+  such as ARC MetaWare & GNU IDE, makefile​
+* Designware and Subsystem drivers, including UART and GPIO, I2C, SPI, etc. ​
+* No middleware, no OS​
+* Easy to port to different platform / OS​
+* One example (UART, GPIO, timer)​
+* Code coverage reach 100% in test. ​
+* MISRA-C compliance​
+* C & C++ support, assembly support
+
+## Supported Boards
+
+* [ARC Software Development Platform](https://www.synopsys.com/dw/ipdir.php?ds=arc-software-development-platform)
+* [ARC EM Starter Kit](https://www.synopsys.com/dw/ipdir.php?ds=arc_em_starter_kit)
+* [ARC EM Software Development Platform](https://www.synopsys.com/dw/ipdir.php?ds=arc-em-software-development-platform)
+* [ARC HS Development Kit](https://www.synopsys.com/dw/ipdir.php?ds=arc-hs-development-kit)
+* [ARC IoT Development Kit](https://www.synopsys.com/dw/ipdir.php?ds=arc_iot_development_kit)
+
+
+## Software Requirement
+
+### embarc_bsp
+
+There are two ways to get embarc_bsp:
+
+#### use RT-Thread ENV tool:
+
+embARC_BSP has been configured as package module, you can just run the command `pkgs --update` in <RTT_ROOT>/bsp/synopsys/boards
+folder using ENV tool.
+
+#### without RT-Thread ENV tool:
+
+We can get it from github: [embarc_bsp](https://github.com/foss-for-synopsys-dwc-arc-processors)
+
+The default path for embarc_bsp is <RTT_ROOT>/bsp/synopsys/boards/packages/embARC_bsp-upstream,
+when you use other path, please set the environment variable `EMBARC_BSP_ROOT`.
+
+### Toolchain
+
+Now both GNU and MetaWare Toolchain are supported, set the System environment variable RTT_CC select the toolchain.
+
+GNU:
+
+    set RTT_CC=gnu
+
+MetaWare:
+
+    set RTT_CC=mw
+
+#### GNU
+
+The ARC GNU Toolchain offers all of the benefits of open source tools, including complete source code and a large install base. The ARC GNU IDE Installer consists of Eclipse IDE with [ARC GNU plugin for Eclipse](https://github.com/foss-for-synopsys-dwc-arc-processors/arc_gnu_eclipse/releases), [ARC GNU prebuilt toolchain](https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases) and [OpenOCD for ARC](https://github.com/foss-for-synopsys-dwc-arc-processors/openocd>)
+
+Here, the ARC GNU toolchain is installed to `c:\arc_gnu`. If not, please change the path configuration in rtconfig.py.
+
+When you use GNU Toolchain, you need to install [Zadig](http://zadig.akeo.ie) to replace the default FTDI driver with WinUSB driver. See [How to Use OpenOCD on Windows](https://github.com/foss-for-synopsys-dwc-arc-processors/arc_gnu_eclipse/wiki/How-to-Use-OpenOCD-on-Windows>) for more information.
+
+#### MetaWare
+The [DesignWare ARC MetaWare Development Toolkit](https://www.synopsys.com/dw/ipdir.php?ds=sw_metaware) builds on a long legacy of industry-leading compiler and debugger products for embedded applications. It is a complete solution that contains all the components needed to support the development, debugging, and tuning of embedded applications for the DesignWare® ARC® processors.
+
+Here, the ARC MetaWare toolchain is installed to `C:\ARC\MetaWare`. If not, please change the path configuration in rtconfig.py.
+
+
+
+
+
+## Build & Debug
+
+### Build embarc_lib
+
+please run the following cmds to build embarc_lib
+
+    cd <rt-thread-root>/bsp/synopsys/boards
+    scons --embarc_build
+
+### Build
+
+please run the following cmds to build
+
+    cd <rt-thread-root>/bsp/synopsys/boards
+    scons
+
+### Debug
+
+After compile, please use the following cmds to debug
+
+    scons --gdb #use gdb debugger
+    scons --mdb #use mdb debugger
+
+
+### How to choose different boards
+
+There are some parameters we can use in scons, for example:
+
+    scons --BOARD=emsk --BD_VER=23 --CUR_CORE=arcem9d --TOOLCHAIN=mw --OLEVEL=O2
+
+ * BOARD: choose the board, we can set: `emsk, iotdk, emsdp, hsdk, axs`.
+ * BD_VER: choose the board version, some boards have different versions, for example,
+   we can set: `10, 22, 23` for emsk board.
+ * CUR_CORE: choose the arc cores, some boards have different cores, for example,
+   we can set: `arcem7d, arcem9d, arcem11d` for emsk board.
+ * TOOLCHAIN: choose the toolchain to build embarc_lib, we can set: `mw, gnu`.
+ * OLEVEL: choose the build optimize level, we can set: `O0, O2, Os`.
+
+For more information, you can run the command `scons -h`.

- * \defgroup	DEVICE_HAL_SPI_CTRLCMD		SPI Device Control Commands
- * \ingroup	DEVICE_HAL_SPI
- * \brief	Definitions for spi control command, used in \ref dev_spi::spi_control "SPI IO Control"
- * \details	These commands defined here can be used in user code directly.
- * - Parameters Usage
- *   - For passing parameters like integer, just use uint32_t/int32_t to directly pass values
- *   - For passing parameters for a structure, please use pointer to pass values
- *   - For getting some data, please use pointer to store the return data
- * - Common Return Values
- *   - \ref E_OK,	Control device successfully
- *   - \ref E_CLSED,	Device is not opened
- *   - \ref E_OBJ,	Device object is not valid or not exists
- *   - \ref E_PAR,	Parameter is not valid for current control command
- *   - \ref E_SYS,	Control device failed, due to hardware issues such as device is disabled
- *   - \ref E_CTX,	Control device failed, due to different reasons like in transfer state
- *   - \ref E_NOSPT,	Control command is not supported or not valid
- * - Usage Comment
- *   - For SPI poll or interrupt read/write/transfer operations, only 1 operation can be triggered.
- *     If there is a operation is running, any other operation will return \ref E_CTX
- *   - If SPI is in transfer, then the following operations may return \ref E_CTX. Like
- *     \ref SPI_CMD_SET_CLK_MODE, \ref SPI_CMD_SET_TXINT_BUF, \ref SPI_CMD_SET_RXINT_BUF,
- *     \ref SPI_CMD_SET_TXINT, \ref SPI_CMD_SET_RXINT, \ref SPI_CMD_ABORT_TX, \ref SPI_CMD_ABORT_RX,
- *     \ref SPI_CMD_FLUSH_TX, \ref SPI_CMD_FLUSH_RX, \ref SPI_CMD_SET_DFS, \ref SPI_CMD_TRANSFER_POLLING,
- *     \ref SPI_CMD_TRANSFER_INT, \ref SPI_CMD_ABORT_XFER, \ref SPI_CMD_MST_SEL_DEV, \ref SPI_CMD_MST_DSEL_DEV,
- *     \ref SPI_CMD_MST_SET_FREQ and \ref dev_spi::spi_write "SPI Poll Write" or \ref dev_spi::spi_read "SPI Poll Read".

-# Synopsys DesignWare ARC EM Starter Kit
-
-## Overview
-
-The DesignWare™ ARC™ EM Starter Kit(EMSK, emsk) is a low-cost, versatile
-solution enabling rapid software development and software debugging, and
-profiling for the ARC EM Family of processors. The EM Family includes the EM4,
-EM6, EM5D, EM7D, EM9D, and EM11D cores.
-
-![EM Starter Kit](figures/emsk_board.jpg)
-
-The EMSK consists of a hardware platform and a software package, including
-pre-installed FPGA images of different configurations of the ARC EM Processor
-with peripherals.
-
-The development board is based on a Xilinx Spartan-6 LX45 FPGA. It supports
-hardware extensions using six 2x6 connectors supporting a total of 48 user I/O
-pins (plus power and ground pins) that can be used to connect components such
-as sensors, actuators, memories, displays, buttons, switches, and
-communication devices. A Digilent Pmod™ compatible extension board containing
-a four-channel 12-bit A/D converter with an IIC interface and an AC power
-adapter are included in the package.
-
-## Board Resources
-
-| Hardware | Description |
-| -- | -- |
-| SOC | EMSK |
-| Core | EM9D                                   |
-| Arch       |  32-bit ARC EM                                         |
-| Frequency  |  20/25 Mhz                                            |
-| RAM | 128 MB DDR RAM + 256 KB Instruction CCM + 256 KB Data CCM |
-|Flash | 16 MB SPI Flash for FPGA configuration with 128 KB reserved for application |
-
-## Usage
-
-### FPGA Configuration
-
-Current, only em9d configuration is supported and tested for RT-Thread. However,
-it's can be easily applied to other configurations because all emsk configurations almost share the same memory map and periphreals.
-
-Please refer [EMSK configuration](https://embarc.org/embarc_osp/doc/build/html/board/emsk.html) for details.
-
-### Toolchain
-
-The ARC GNU Toolchain offers all of the benefits of open source tools, including complete source code and a large install base. The ARC GNU IDE Installer consists of Eclipse IDE with [ARC GNU plugin for Eclipse](https://github.com/foss-for-synopsys-dwc-arc-processors/arc_gnu_eclipse/releases), [ARC GNU prebuilt toolchain](https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases) and [OpenOCD for ARC](https://github.com/foss-for-synopsys-dwc-arc-processors/openocd>)
-
-Here, the ARC GNU toolchain is installed to `c:\arc\gnu`. If not, please change the path configuration in rtconfig.py.
-
-### Compile
-
-please run the following cmds to compile
-
-    cd <rt-thread-root>/bsp/synopsys/emsk_em9d
-    scons
-
-## Debug
-
-You need to  install [Zadig](http://zadig.akeo.ie) to replace the default FTDI driver with WinUSB driver. See [How to Use OpenOCD on Windows](https://github.com/foss-for-synopsys-dwc-arc-processors/arc_gnu_eclipse/wiki/How-to-Use-OpenOCD-on-Windows>) for more information.
-
-After compile, please use the following cmds to debug
-
-    scons  --gdb
-
-
-## Supported Drivers
-
-| Driver | Supported | Comment  |
-| ------ | ----  | :------:  |
-| UART1 |  yes |  USB-UART for shell & log |
-| UART0 | yes | PMOD A UART for UART modules, e.g. esp8266 |
