[U-Boot] u-boot USB status

[Marcel]

Hi,

I've been away for some time and I wonder if there has been any progress on 
the u-boot USB branch.

What I want to do is upgrade my kernel and rootfs via USB. I'm using an Atmel 
SAM9.

I wonder about the status and if any additional work is needed I'm willing to 
help with the project of course. I'm very familiar with USB as I've written 
many bootloaders with USB support before (all proprietary) but I'm just a 
little  familiar with the u-boot USB structure.
My intentions are to contribute to the project because I think USB upgrading 
is a must to make things a bit more user friendly.

Any pointers to get me going again are highly appreciated. The first thing I 
need is USB support in u-boot for my SAM9, from there I think it's a fairly 
easy job. 

Thanks,
Marcel
