Thanks for the suggestion, Alan. I will be adding this to my proposal.
Also, which BSP would you recommend that I pick up ? Is there any list
of currently added BSPs from which I can choose?

I was also thinking for that. I have a Raspberry PI 1/B+ and a
majority of users have either 1/B+ or 2/B. Probably we can start with
1/B+ and then enable the other models.

Sure, I had left some buffer time in my proposal, probably if things
goes as per plan that time can be used for USB support for the
BCM2835.
