Hi Alan, Thanks for your feedback. I've implemented all your suggestions 
and I'll resubmit.

I had a question about the status of the fpga-manager framework. Is 
there active work going on? I was wondering if there were any patches 
for specifying a firmware file from device-tree? and/or if there were 
any patches for loading firmware from userspace - something like this: 
"cat firmware.bin > /dev/fpga0"?

Only being able to load firmware from kernel C-code is rather a 
limitation - though I suppose the framework is quite early in development.

Thanks
Joel
