while adding usb support is fine, I see no reason to add smsc95xx support because contrary to harmony, paz00 does not contain an ethernet port.
Is the SMSC95xx only an internal part, or could it be present on a user-pluggable USB dongle? I wasn't sure, so I left it in.
Looking at the driver (and the Linux kernel driver and SMSC's website), it supports both the standalone USB->Ethernet 9500 chip that's likely to be in USB Ethernet dongles, and various combo USB hub + Ethernet chips that are found on motherboards (e.g. Harmony). As such, I think it's reasonable to leave this config option enabled on Paz00 and other Tegra boards even when such a chip isn't on the board itself. Do you agree?
Following this argument would mean to enable all current (and future) usb devices and we end up with an u-boot which is to heavy to swim. I only have a mcs7830 which is unfortunately not supported. Do you have a SMSC95xx based usb adapter or plan to get one? In this case I think it would be ok to enable it, otherwise I tend to disagree here. On the other hand, given that you kindly take care of the paz00 code, the decision is up to you.
Just my two cents,
Marc
