[U-Boot] Micrel Ethernet controller with SPI

Hi, I'm not sure whether I'm supposed to ask this question as I am still new to this list.

I am working on a project using U-boot but the Ethernet controller is the Micrel KSZ8851. Does a driver exist that supports this chip? I assume it would be in drivers/net/

I don't have it in my version which is based on 2008.10

Before I go through the effort to write one, I thought I'd ask whether the U-boot community has one or perhaps someone is working on one.

Thanks in advance, Steve
