[U-Boot-Users] Can ethernet be disabled?

I'm porting u-boot to a custom PXA255 board. At present there is no network interface so I'm only interested in loading data over a serial port. Can I disable network support pre-compilation to cut down the size of u-boot?

ie. Is there an equivalent of " #define CONFIG_LCD 0 " to disable network support.?

So far builds fail unless I define at least one network controller.

Cheers
