Compile time error, compiling Xilinx Linux 2.6 for XPS LLTEMAC

That interrupt is defined if you build a xps_ll_temac with the
xps_ll_fifo interface. Since you already stated that you're using the
mpmc, I'm going to assume that you have it connected to a SDMA
controller on the mpmc. As such the driver should be looking for that
definition, and not the FIFO interrupt. I don't have your version of the
virtex_devices.c to have a reference as to how the platform device is
being defined, so hopefully either Stephen N can chime in w/ more
information, or point me to the version of the virtex_devices.c that
you're using and I can try to provide some more assistance.

that should be a small problem, and i think that its solution should be

I generate a base system using EDK 9.2.02 , the base system contains
XPS_LL_TEMAC , MPMC and other components,
I generate the software libraries and copy xparameters file into proper
kernel folder. I configure that kernel and add kernel support for

while doing make I encounter this error:

arch/ppc/syslib/virtex_devices.c:455: error:
'XPAR_LLTEMAC_0_LLINK_CONNECTED_FIFO_INTR' undeclared here (not in a

I think that this definition should be available in xparameters_ml403.h
file but i see that there is no such definition. 
I added a dummy definition for myself there to complete kernel
compilation, don't know the correct value for it of course.
