arc: Add support for IoT development kit
The DesignWare ARC IoT Development Kit is a versatile platform
that includes the necessary hardware and software to accelerate
software development and debugging of sensor fusion,
voice recognition and face detection designs.
More information is avaialble here [1] and here [2].
The board is based on real silicon with
ARC EM9D-based Data Fusion IP Subsystem.
It sports a rich set of I/O including
* DW USB OTG
* DW MobileStorage (used for micro SD-card)
* GPIO
* multiple serial interface including DW APB UART
* ADC, PWM and eFlash, SRAM and SPI Flash memory
* Real-Time Clock (RTC)
* Bluetooth module with worldwide regulatory compliance
(FCC, IC, CE, ETSI, TELEC)
* On-board 9-axis sensor (gyro, accelerometer and compass)
Extensible with Arduino, Pmod, mikroBUS connectors and a 2x18
extension header.
One of the most interesting features for developers is built-in
Digilent USB JTAG probe so only micro-USB cable is needed!
