Support for the Nordic nRF51 Dongle.
The nRF51822 is a multi-protocol SoC ideally suited for Bluetooth® low energy and 2.4GHz ultra low-power wireless applications from Nordic Semiconductor. The nRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU with 256KiB flash + 16KiB RAM. The embedded 2.4GHz transceiver supports Bluetooth low energy as well as 2.4GHz operation.
Nordic's development kit contains two different boards:
While the pca10000 contains an on-board J-Link debugger, the pca10005 boards have to be flashed/debugged using the (included) external J-Link device.

The nRF51822 PC10000 board is shipped with an on-board JLink debugger. However the PC10004/5 board uses an external flash tool as seen in the Image above. Under Linux, the easiest way flashing the nRF51822 is using the JLink tool(version >4.85) from Segger.
To interact with the board just start the tool using the following command:
# JLinkExe -device nrf51822
For RIOT itself there is a Flash-Script available. When using any of the Examples type in the following command:
# Make -B clean flash
