Well, As you know, we now need a PLB version, XPS_LL_TEMAC is connected to PLB not MPMC2...yes I remember those days of Xilinx GSRD and MPMC2 however it seems that the current architecture has slight changes. 

about the git repository of Xilinx, Although I do not believe on it, I'll give it a try...thanks for info.

well, what about Grant Likely... and his git tree?

In case anyone is interested, I'm currently working on 
an almost-kernel-ready version that will be self-contained based on the LL-DMA 
version (the native MPMC port, not the PLB). It's based upon the old adapter 
from MontaVista, that I originally ported to 2.6 and the MPMC2. Unfortunately, 
it won't be ready for another few weeks since I'm working on hardware images

thanks for you reply david,

As far as I know the Linux driver 
for Xilinx PLB TEMAC was two parts : 1- adapter.c and 2- the rest of the driver 

Only adapter.c was really a linux related file and the rest of the 
files were Xilinx generic driver code for PLB TEMAC.


now, I know EDK 9.2 generates the needed Linux support package and needed 
related files, so if this is the case can we use these files as the needed 
driver in our linux kernel?

by the way, i did never hear about this git 
repository before...can you describe us, where is it and how we can access it 
and which projects are now hosted by it?
