Query on Global Offset Table

Hello,
I had a query regarding the usage of Global Offset Table.I understand that the GOT is primarily used in dynamically linking some file to a executable, like dynamic shared libraries.In u-boot though we compile certain modules as static libraries,which would be bound to the executable at link time.What do we use the GOT for in u-boot.My guess is it's something to do with code relocation to the main memory.Would be helpful if someone elucidates on this.
