First, you'll need the attached sysace-without-virtexii patch, which
has not been pushed to the linuxppc-2.4 tree yet. This fixes some
V2PRO dependencies when XILINX_OCP is activated.
I started by editing the file platforms/xilinx_ocp/xparameters.h:
===== arch/ppc/platforms/xilinx_ocp/xparameters.h 1.1 vs edited =====

The CONFIG_JSE is for my board. I then added the xparameters_jse.h
file next to the xparameters_ml300.h that has the pertinent values
for my system. I've attached mine as a working example.
I also edited the arch/ppc/config.in so that the right defines
are enabled:

This activates CONFIG_XILINX_OCP when I config the JSE board,
and that allows the XILINX_SYSACE to be selected. From here,
make sure CONFIG_XILINX_SYSACE=y in your .config and you are
set.
