warp: Add initial WaRP Board support
The WaRP Board is a Wearable Reference Plaform. The board features: - Freescale i.MX6 SoloLite processor with 512MB of RAM - Freescale FXOS8700CQ 6-axis Xtrinsic sensor - Freescale Kinetis KL16 MCU - Freescale Xtrinsic MMA955xL intelligent motion sensing platform The board implements a hybrid architecture to address the evolving needs of the wearables market. The platform consists of a main board and an example daughtercard with the ability to add additional daughtercards for different usage models.
