The usb_board_init() prototype was changed sometimes ago and now the
return value is checked (it was not when the trizeps module was added to
u-boot). So now the usb initialization can fail (and it does..).

To be honest, this fix is not related to this patch, but because it is
a small change I inserted here. Should be enough if I add a comment
about it in the git commit or do you think it is required to pull it
apart in an another patch ?

You are right, I will drop this change here and I will send another
patch to clean up these parameters (and CONFIG_EXTRA_ENV_SETTINGS, too).

There is only one ethernet controller available and for this reason I
cleared the NET_MULTI flag. However, I see other boards use another
approach and leave this flag set. I can let the same approach here.

Thanks, I'll fix it.

IIRC we you check the ifdef only not the value

This doesn't really mean that there are multiple Ethernet controllers.  
It just means that U-boot should use the framework that supports 
multiple interfaces.  Most drivers only support one framework or the 
other (MULTI or !MULTI), but in a couple of releases !MULTI will be 
going away completely.

Also, we only check if CONFIG_NET_MULTI is defined, not its value.

Ben
