So, in this case, our base system, created with EDK 9.2 will not be the same as previous systems, as shown in <br>http://www.xilinx.com/esp/wired/optical/xlnx_net/mpmc.htm<br>PLB and OPB usage is limited to a small area of design...<br><br><blockquote><hr>Subject: RE: Xilinx XPS_LL_TEMAC vs PLB_TEMAC<br>Date: Wed, 23 Jan 2008 07:43:14 -0600<br>From: mike.koss@ngc.com<br>To: mamsadegh@hotmail.com; dhbaird@gmail.com; linuxppc-embedded@ozlabs.org<br><br>

<div></div>Hi<br><br>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.
<br><br>about the git repository of Xilinx, Although I do not believe on it,
I'll give it a try...thanks for info.<br><br>well, what about Grant Likely...
and his git tree?<br><br>

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 currently.</span></font></div>

<div></div>thanks for you reply david,<br><br>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 files<br><br>Only adapter.c was really a linux related file and the
rest of the files were Xilinx generic driver code for PLB
TEMAC.<br><br>correct?<br><br>then 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?<br><br>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?<br><br><br>thanks<br><br><br>> Date: Mon, 21 Jan 2008 00:54:30
