a211091855 iot_dk: Link for eFlash
That's what we'll have in production.
But note it won't work for loading via JTAG as
eFlash is not directly writable, one needs to use
prebootloader to flash uboot.bin from SD-card into eFlash.

18e8923f6c iot_dk: Disable networking support
There's no Ethernet controller on the board so no point in having
networking support. This also saves us 5.5 kB of precious memory.

5396e8b1dd 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!
