[U-Boot] [PATCH v2 0/4] DFU implementation for Atmel SAM9G45

[Marcel Janssen]

Hi,

I hope this one gets through correctly.

I know it's know what optimal as it should apply to the current 'work'
but I had some issues doing that and no time to find out what the issue is.

If possible, please apply to cdc-at91
If not, than I will be reviewing it in a couple of months I guess.

The code I send is compiling in cdc-at91 branch and working well for my board 
and should work as well for at91_udc boards I think.

If anyone likes to help out on this, please go ahead !

btw, thanks again to all people who already helped. 
I perhaps have a few hours left this week to work on this, but no more than 
that. I hope for someone to take over from me at this point.

Best regards,
Marcel
