I mentioned this as well directly after posting this patch for the first time.
But anyway, if you look at 'cdc-at91' branch of u-boot-usb you can see
all the other patches that are required to make it compile properly.
Including the timer fix for the at91 family.

I see you use a rather old compiler.
I tested with a GCC 4.3.4 (CodeSourcery 2009q1) compiler which works
okay. I also noticed that the current make structure of U-boot is more
picky on linker usage, and even unresolved externals result in
crashing linkers. This has nothing to do with this patch though.

Kind regards,

Remy
