Hello everyone,
I am trying to port U-Boot to an EP885C development board in order to practice porting before I have to port to a board that my company is in the process of building. I know that Yuli Barcohen will soon release a patch that ports to the EP885C, but I felt that I had to plow ahead before I get that patch as a reference for porting.
I began by making the directories suggested in the faq and changing values for what board specifications I could determine. I am sure that I am missing some important values, but I wanted to test compilation. Upon doing so, I received the following errors as the compiler attempted to build u-boot.map:

If someone could help me determine how to make the build process find the eth functions (I see that their code is located in net/eth.c) I would be very appreciative. I am not very knowledgeable about relocation.
Also, if Yuli is reading this, even if your patch is incomplete, any reference material that you could provide to help me replicate your port would be greatly appreciated.
In eager anticipation, Will Haines
