Participation in GSoC 2016

Hi Deval,
Your proposal looks good. I would suggest adding a step where you build a
known BSP with BSD lib support. It will help you become familiar with the
development process.
You should also address which Raspberry Pi model you will support. Now that
there are so many Raspberry Pi models, it might make the project more
complicated:
Original raspberry Pi Model A & A+: a single built in USB port in the
BCM2835 CPU. No ethernet or USB hub.
Raspberry Pi Model B & B+: USB hub and Ethernet in LAN9512 chip.
Raspberry Pi 2 Model B: USB hub and Ethernet in LAN9514 chip.
Raspberry Pi 3 Model B:  I would not worry about this one yet.
Raspberry Pi Zero: A single USB OTG port , no ethernet or USB hub.

I would pick one of them and get it working before seeing if another model
could be supported.

If the Raspberry Pi 1/B+ and 2/B Hubs are functionally the same ( LAN9512
vs. LAN9514 ), this would support the widest range of devices out there.

If you have time, I would love to see USB support for the BCM2835 on the Pi
Model A+ and especially the Pi Zero.

Thanks,
Alan
