[U-Boot-Users] About CS8900A's MAC address

Hi all, I am porting u-boot-1.1.3 to a Samsung S3C44B0X based board that I bought several months ago. It consists of a CS8900A as its ethernet controller. When I write a configuration header file (include/configs/jx44b0.h) for the board, I find that I don't know the CS8900A's MAC address. I wonder how to figure it out. Sorry for my poor English. Any advice should be appreciated.
